One dinner at a Pharisee's house, served in five courses, and the arithmetic hidden in each: what it costs to be watched, which seat to take, whom to invite, how a full hall empties in four rounds and fills again from the hedges, and why a king with ten thousand men sends an envoy. For people who count for a living, and for anyone who has wondered whether the old book still has something to say to them.
Today's text is Luke 14.
I have never preached before, and you have probably never been preached at by a Jewish investor, so we begin even. I chose this chapter because it is a chapter about seats, and our whole working lives are about seats: a seat on the board, a seat at the table, a seat in the deal everyone wants, the seat a CEO speaks from when he tells you what the year will bring. Who is watched in them. Who jostles for them. Who is offered one and sends an excuse. Who sits down in one to count before he builds. Luke puts all of it at one dinner, on one Sabbath, in the house of a leading Pharisee who had invited a famous teacher to eat with him and then sat back to see what he would do.
So I will serve the chapter as Luke serves it, in five courses, each with a little arithmetic, the way a good dinner comes with wine: a model that shows why the scene works as it does, a case from this year's markets, and a chart. I have tried to make the charts funnier than the models.
When he went into the house of one of the rulers of the Pharisees on a Sabbath to eat bread, they were watching him. Behold, a certain man who had dropsy was in front of him. (Luke 14:1-2)
Picture the room. The Pharisees were the most respected religious movement of the day, devout laymen who kept the Law of Moses with great care, and this host was one of their leaders. Imagine being asked to dinner by the analyst who covers your company, with his research department at the table, Compliance at the far end, and the downgrade already drafted. These were serious men, and they had come to see whether this teacher was. The table is laid. And standing in front of the famous guest, before anyone has lifted a cup, is a man with dropsy, the old name for a body swelling with fluid, which often meant a failing heart. Luke does not say how he came to be there. He says only that they were watching, because it was the Sabbath, the day set apart for rest, and healing was work.
Jesus did not make them wait. He asked the question out loud before anyone could ask it of him: "Is it lawful to heal on the Sabbath?" Silence. He healed the man, let him go, and asked which of them would leave a son or an ox at the bottom of a well until the Sabbath was over. "They couldn't answer him regarding these things."
Now let's discuss the mathematics of being watched by someone who is waiting for you to slip. Suppose a good man "slips" once in a hundred days from his usual gentlemanly demeanor: a sharp word, a rule bent to help someone, a form filed late. Watch him for a year and the chance that you catch him at some sin, major or quite minor, is 97 percent; by the sixty-ninth day it is already a coin toss. Make him a very careful man who slips once in five hundred days, watch him for three years, about the length tradition gives the public ministry of Jesus, and the chance is still 89 percent. Anyone watched long enough will be found at fault. A fault found under a microscope tells you as much about the microscope as about the specimen.
The same arithmetic runs in my own account, where the watcher is the market. An investor like me loves to sell puts on technology and chip stocks, where the premiums are juicy. A put is a promise: for a fee paid to me today, I agree to buy 100 shares at a set price if the buyer asks before a set date. Most days nobody asks; within a few days I buy the promise back for less than I was paid, and sell another. The week I fear is the week every chip and software name falls at once and the buyers, who have paid me a little every time for the privilege of watching, finally ask. That is assignment: the shares arrive in my account and the set price leaves it, whatever they are worth by then. Twenty such promises on shares near $500 is a bill of $1 million, due the same morning, for shares now worth well below what I agreed to pay. Since 2016, chip, computer hardware and software stocks have all fallen 5 percent or more in the same week ten times in 557 weeks, about once in fifty-six. A seller who comes back every week meets that week, by the Pharisees' arithmetic, with 61 percent probability inside a year and 94 percent inside three. The watcher needs only patience, and the market has more of it than I do.
The formula behind both curves, for the curious: if each day carries an independent chance p of a slip, the chance that n days of watching catch at least one is 1 - (1 - p)n. At p = 1 percent, 1 - 0.99365 = 97.4 percent over a year; at p = 0.2 percent, 1 - 0.9981,095 = 88.8 percent over three years; even odds arrive on day ln(0.5) / ln(1 - p), day 69 at 1 percent and day 346 at 0.2 percent. By the week, with p = 10 / 557, about 1.8 percent: 1 - (1 - p)52 = 61.0 percent inside a year and 1 - (1 - p)156 = 94.1 percent inside three.
Watching is also a job, and a job can be bought. George Stigler showed in 1971 that the industry a regulator watches usually ends up owning the rule book. It asks for the rules. It helps shape them. It lives comfortably inside them, and the newcomer at the door finds that every rule was cut to fit the people already in the room. A rule can also be a weapon. In 1983 Steven Salop and David Scheffman showed that a firm can win by raising a rival's costs instead of cutting its own prices, and the cheapest way to raise a rival's costs is a rule you already obey and he does not. So when the watchers gather around a newcomer, ask two questions. Who pays them? And whose costs does their rule raise?
This year the watchers have gathered around a new table. Kalshi, an exchange designated by the federal Commodity Futures Trading Commission in 2020, sells event contracts: a contract pays $1 if something happens, a team wins or the Federal Reserve cuts rates, and nothing if it does not. State gaming regulators say a contract on a football game is a sports bet and needs a state license; the exchanges say a federally regulated market answers to federal law. The courts have split. In April the federal appeals court in Philadelphia sided with Kalshi against New Jersey, two judges to one, at an early stage of the case; since August the courts in San Francisco and Cincinnati have sided, unanimously, with Nevada, Ohio and Tennessee. New Jersey has asked the Supreme Court to take the case; by its count the quarrel has run to at least 39 lawsuits in 20 states. I take no side. Learned judges disagree. I ask only what Jesus asked at that table: is the same rule applied to everyone who does the same thing?
Sometimes the watchers are right. For years Dan McCrum of the Financial Times reported that the accounts of Wirecard, a German payments company, did not add up. Germany's financial regulator answered by banning short selling of its shares and filing a criminal complaint against the reporters. In June 2020 Wirecard said there was a "prevailing likelihood" that €1.9 billion in its trust accounts did not exist, and three days later it filed for insolvency. The reporters were right. The official watcher had been watching the wrong people.
The watchers of Theranos were right too. On October 15, 2015, John Carreyrou of the Wall Street Journal reported that Theranos, a blood-testing company its investors valued at $9 billion, ran only a fraction of its tests on the finger-prick device it was famous for. The company called the story "factually and scientifically erroneous." On January 3, 2022, a federal jury convicted its founder, Elizabeth Holmes, of conspiring to defraud investors and of three counts of wire fraud; she was sentenced to eleven years and three months, and on May 30, 2023, she reported to a federal prison camp in Bryan, Texas. Both times the first watcher to be right carried no badge. He had a notebook, and patience, not unlike my team here at Vista Research, except that ours can be hired.
And when the watchers find nothing at all? Daniel's rivals in Babylon "could find no occasion or fault, because he was faithful," so they had a law written to catch him "concerning the law of his God" (Daniel 6:4-5). Victor Hugo gave the watcher a face, Inspector Javert, who hunts Jean Valjean for half a lifetime and is undone at last by the one thing his ledger has no column for: mercy, shown to him by the man he hunted.
So, are you being watched, or are you the watcher? If you are the watcher, remember the curve: watch anyone hard enough and you are all but certain to find something. So ask yourself, before you look, what you are really looking for, and be mindful of what the finding will do. Ask who pays you, and whether you would have found the same fault in his competitor. And when you find nothing, as Daniel's rivals found nothing, say so and go home. I have always wondered whether Theranos, with more coaching, more time, more oversight and more rigor, might have reached its breakthrough and helped a great many people. Instead the company was shut down and its founder went to prison. The record is plain: a jury found that she defrauded her investors, and patients had received results the company itself later voided or corrected. Carreyrou was right. But a watcher can be right and still owe the watched two things: a motive he can name out loud, and the mercy he would want if the microscope were turned around. Watching changes the course of a life, and given the near certainty of finding something, I wonder whether the watchers always have enough compassion in their hearts. If you are being watched, ask the question before they do, as Jesus did at that table. Make no promise you could not keep in the week when everything falls at once. And when the watcher slips into your hands, as Javert slipped into Valjean's, let him go. Valjean's mercy did what a lifetime of running never did: it ended the hunt.
He spoke a parable to those who were invited, when he noticed how they chose the best seats, and said to them, "When you are invited by anyone to a wedding feast, don't sit in the best seat, since perhaps someone more honorable than you might be invited by him, and he who invited both of you would come and tell you, 'Make room for this person.' Then you would begin, with shame, to take the lowest place. But when you are invited, go and sit in the lowest place, so that when he who invited you comes, he may tell you, 'Friend, move up higher.' Then you will be honored in the presence of all who sit at the table with you. For everyone who exalts himself will be humbled, and whoever humbles himself will be exalted." (Luke 14:7-11)
The guest who was being watched was watching too. While they studied him, he studied them, and what he saw was a room of important people edging toward the places nearest the host. You have seen that room. It is the investor dinner where the CEO has not yet arrived, the two chairs beside his are the prize, and a dozen people who manage other people's money drift toward them while studying the wine list. The advice was old; Proverbs had given it centuries before: "Don't exalt yourself in the presence of the king, or claim a place among great men; for it is better that it be said to you, 'Come up here,' than that you should be put lower in the presence of the prince" (Proverbs 25:6-7).
It is also good arithmetic. In 1992 Amos Tversky and Daniel Kahneman measured how people weigh losses against gains, and for their typical subject a loss stung about 2.25 times as much as a gain of the same size. Count the seats in that currency. You arrive before the host has placed anyone, and you choose: seat yourself at the top, uninvited, or take the bottom and wait. Keep the top seat and you have one point of honor. But if someone grander walks in, you are sent to the bottom in front of everyone: two points lost, and because it is a loss it feels like four and a half. Take the bottom, and either nothing happens or the host says "Friend, move up higher," worth two points, because the whole table sees it. Now count a hundred dinners. Seat yourself at the top at all hundred, and suppose a grander guest turns up at fifteen of them. At the other eighty-five you keep your point: 85. At those fifteen you take the walk, four and a half each: 67.5 lost. Net, 17.5. Sit at the bottom at all hundred with a host who calls the humble up at ten of them, and you collect two points ten times: 20. The bottom wins. It wins by more the oftener the host calls people up, and by more the oftener a grander guest arrives; the top seat pays only when the grander guest is rarer than about one dinner in seven, and with a host who calls people up one dinner in four, rarer than one in eleven. With a host who does it every other dinner, never. On almost any night, the lowest place wins.
The formula, for the curious: let L be loss aversion (2.25), p the chance a grander guest arrives and q the chance the host calls you up. Seating yourself at the top is worth (1 - p) x 1 - p x 2L; sitting at the bottom is worth 2q. The top pays only when p < (1 - 2q) / (1 + 2L): 14.5 percent at q = 10 percent, about one dinner in seven; 9.1 percent at q = 25 percent, one in eleven; zero at q = 50 percent. Over 100 dinners, with a grander guest at n of them and the host calling you up at m, the top seat scores 100 - 5.5n and the bottom 2m: 17.5 against 20 at n = 15 and m = 10. Later studies put L nearer 1.3 to 2 (Walasek, Mullett and Stewart, 2024; Brown, Imai, Vieider and Camerer, 2024), which moves the first bound to 22 or 16 percent; the conclusion holds.
Business has its own seating chart. It is called guidance. Each year a publicly traded company tells investors how fast it expects to grow, and in doing so it chooses a seat. Forecasts tend to start high and be walked down to a level the company can beat, as Scott Richardson, Siew Hong Teoh and Peter Wysocki found in 2004, and a growth company that disappoints is punished out of all proportion: Douglas Skinner and Richard Sloan called it the earnings torpedo.
I own shares of Boston Scientific, so I write about it as a guest at that table, and I have watched it at two dinners. In 2025 it took the low seat. In February it guided to organic revenue growth of 10 to 12 percent (growth from its own businesses, leaving out currency moves and acquisitions); as the year came in better it raised the range in April, July and October, delivered 15.8 percent, and was called up, the shares rising on the days of the spring and summer raises.
In February 2026 it chose a seat at 10 to 11 percent, a step down from the 15.8 it had just delivered. The quarter it reported that day beat its own forecast, yet the shares closed down nearly 18 percent, because sales in its heart-rhythm business had come in lighter than expected. Then the year came down the table like a host. In April the company was moved down, to 6.5 to 8 percent, and in July again, to 5 to 6; after a cyberattack disrupted its operations on August 25, it said on September 8 that it was unlikely to keep even that seat. The next seating is October 28. I do not say anyone there was proud; a forecast is a judgment made in good faith about an uncertain year. I say only that markets price a forecast the way a dinner party prices a seat, and a seat once taken is expensive to give back.
He also said to the one who had invited him, "When you make a dinner or a supper, don't call your friends, nor your brothers, nor your kinsmen, nor rich neighbors, or perhaps they might also return the favor, and pay you back. But when you make a feast, ask the poor, the maimed, the lame, or the blind; and you will be blessed, because they don't have the resources to repay you. For you will be repaid in the resurrection of the righteous." (Luke 14:12-14)
Here the sermon could end, if it were a seminar on reputation. It is not. Read alone, the second course makes humility a strategy: sit low, because the expected value is higher. Jesus shuts that door in the next breath. He turns to his host, the man paying for the dinner, and tells him to invite the people who can never invite him back.
Most of commerce runs on the opposite rule. A dinner invitation is a small loan, and the repayment is an invitation. A client entertained is a client expected. Even Aristotle's great-souled man, "the sort of man to confer benefits, but he is ashamed of receiving them," gives back more than he got, so that the other man ends in his debt. He keeps a ledger too; his simply runs in his own favor. The host of Luke 14 is told to give where no ledger can be kept.
Literature knows the counterfeit. Dickens gave us Uriah Heep, the clerk in David Copperfield who calls himself "umble" at every turn while forging his way into his employer's firm. Benjamin Franklin, more honest, put humility thirteenth on his list of virtues, with the instruction "Imitate Jesus and Socrates," and then confessed that "even if I could conceive that I had compleatly overcome it, I should probably be proud of my humility." I know the man. As I wrote in my book, The Scholars' Treasure, I came to fear that the whole story of my life was a boast, and that "I've skillfully hidden the boasting from you, dear reader, with plenty of self-deprecating humor, Bible quotes, literary musings (a boast within a boast), and charitable ideas" (chapter 20, page 243). You will notice I am doing it again. Bible quotes, literary musings, and now a sermon.
The guest list is how Luke 14 tells the real thing from the counterfeit. A gift to someone who cannot repay has no return in this world, so it cannot be a strategy. Jesus dates the repayment "in the resurrection of the righteous." That makes it the longest-dated note in the history of finance, and the only one I know on which the one who pays it back is not the one who borrowed.
There is a company that has kept this guest list for more than a century. In 1909 Milton and Catherine Hershey signed the deed of trust for a school for poor children, and in 1918, three years after her death, he gave it his entire fortune. The Milton Hershey School today houses and educates more than 2,200 children from low-income families with all costs covered, and the trust he set up for them still holds voting control of The Hershey Company; the company says so in its own annual report, and the profits from the chocolate support the school. Those children will never buy a share, sit on the board or return the dinner. That is the test, and an investor can run it on any company's giving: whom does it invite who cannot repay? If every gift lands on a customer, a regulator or a future hire, it is a client entertained. I do not say the giving sells the chocolate; the chocolate does that. I say that a company which has given for a hundred years where no one can repay has shown you how it behaves when no one is watching, and that is something no competitor can buy. The counterfeit is sold everywhere. The real thing has a guest list.
When one of those who sat at the table with him heard these things, he said to him, "Blessed is he who will feast in God's Kingdom!" But he said to him, "A certain man made a great supper, and he invited many people. He sent out his servant at supper time to tell those who were invited, 'Come, for everything is ready now.' They all as one began to make excuses. The first said to him, 'I have bought a field, and I must go and see it. Please have me excused.' Another said, 'I have bought five yoke of oxen, and I must go try them out. Please have me excused.' Another said, 'I have married a wife, and therefore I can't come.'" (Luke 14:15-20)
Someone at the table, eager to change the subject, says something pious about the feast at the end of time. Jesus answers with a story about people invited to exactly that feast who did not come. It is not a comfortable answer.
Kenneth Bailey, who taught for forty years in seminaries in Egypt, Lebanon, Jerusalem and Cyprus, read this parable with a villager's eyes. In the world he knew, a banquet invitation came twice: once in advance, when the guests accepted and the host chose how large an animal to slaughter for the number coming, and again on the day, when a servant was sent to say the meal was ready. To refuse the second call was to break the first promise after the meat was cooked. The excuses, Bailey argued, are insults: no one buys a field without knowing every foot of it, or five yoke of oxen without trying them first. Of the man with the field he wrote, "The statement is a bold-faced lie and everyone knows it." The third man does not even ask to be excused.
Notice the four words before the excuses: "They all as one." The sociologist Mark Granovetter showed in 1978 how a crowd can do what few of its members would do alone. Give each person a threshold: the number of others who must act before he will. A few have a threshold of zero and go first no matter what. Others need to see one person go, or two, or ten. Nobody decides for the crowd. Each decides for himself, looking around.
Let me show it with the parable. Luke gives no number, so give the supper sixty invited guests and number them 0 to 59. Guest k's threshold is k divided by 3, dropping the fraction: guests 0, 1 and 2 have a threshold of zero (the field, the oxen, the wife, who refuse no matter what); guests 3, 4 and 5 need to see one refusal; guests 6, 7 and 8 need two; and so on up to guests 57, 58 and 59, who need nineteen. Now count, round by round, who has seen enough. Round one: three refuse. Round two: three refusals satisfy everyone with a threshold of three or less, guests 0 through 11, so twelve have refused. Round three: twelve refusals clear every threshold up to twelve, guests 0 through 38: thirty-nine. Round four: thirty-nine clears every threshold up to thirty-nine, which is all of them. Sixty. The rule in one line: the number refusing after a round is the number of guests whose threshold is at or below the number refusing before it.
Now change one thing. Let only the man with the field refuse, and let the other two come. One refusal moves only guests 3, 4 and 5: four. Four moves everyone up to guest 14: thirteen. Then forty. Then fifty-eight, and the hall is as good as empty, one round later than before. Had the first three come, nobody with a threshold of one or more would ever have seen a refusal, and nobody else would have stayed away. Three men, three excuses, sixty empty seats.
"That servant came, and told his lord these things. Then the master of the house, being angry, said to his servant, 'Go out quickly into the streets and lanes of the city, and bring in the poor, maimed, blind, and lame.' The servant said, 'Lord, it is done as you commanded, and there is still room.' The lord said to the servant, 'Go out into the highways and hedges, and compel them to come in, that my house may be filled. For I tell you that none of those men who were invited will taste of my supper.'" (Luke 14:21-24)
Picture the servant on the road home, the smell of the roast still on his clothes and nothing to bring his master but excuses. The master's first word to him is "quickly," and every airline knows why. A seat that leaves empty can never be sold, and a supper ready tonight is spoiled tomorrow. Airlines call the science revenue management: fill the perishable seat at whatever price the hour allows. Its first rule, Ken Littlewood's of 1972, fits in one line: keep holding a seat back for a later, higher fare only while the chance of selling it at that fare, times that fare, is at least the lower fare on offer now. The host goes further than any airline. There is no later, higher fare he is waiting for, so he holds nothing back: he fills his last seats for nothing, with people who cannot pay, and when the hall is nearly full he sends the servant out again, because there is still room. (The refilling in my chart, forty seats from the streets and the last twenty from the hedges, is my illustration; Luke gives no numbers there either.)
Business has its own hall that fills from the hedges. Clayton Christensen, whom I was honored to host as guest of honor and speaker at the Silicon Valley Innovation Institute before his death in 2020, called it competing against nonconsumption: serving the people the established firms never invited. Robinhood, whose shares I also own, is a case in point. When it went public in 2021, the median age of its customers was 31, and over half of those funding accounts said it was their first brokerage account. Its oldest table is equities: the money it earns when its customers buy and sell shares of stock. Its newest is event contracts: a contract that pays $1 if a stated thing happens, a team wins or the Federal Reserve cuts rates, and nothing if it does not, and Robinhood earns a little each time a customer trades one. In the second quarter of this year the new table earned $156 million, more than ten times as much as a year earlier and more than the $129 million the old table earned from stocks. That is the parable's arithmetic in a quarterly report: a company built for the uninvited found a second hall and filled it faster than the first. Whether that new table is a futures market or a sportsbook is precisely what the watchers of the first course are arguing about in court.
I have lived this parable from the host's side. In 1994 my partners and I founded our first company, a network of professors available for consulting. The evening we left our day jobs to run it, we celebrated at the Pump Room in Chicago. As I wrote in my book, "Nearing the end of the Puligny-Montrachet, one of us mused about who our first clients would be. Suddenly the dinner turned from celebratory to tense" (chapter 6, page 65). We had spent three years setting the table and had not invited a single guest, not unlike these Vista Research inquiries and essays, which I have so far written for exactly zero promised readers. So we sent the invitations: "Five hundred emails, 499 rejections, and one golden nugget" (page 67). At McKinsey two partners took their seats at the far end of a long table from me (page 67), and one of them told me, "We are McKinsey. We are the experts" (page 68). More than a year on, the three of us were down to our final $10,000 and spent it on one advertisement in the Wall Street Journal, as close as a young company gets to the highways and hedges. Then, in the spring of 1997, the phone rang. Kimball Anderson, a Chicago trial lawyer, needed experts for a patent case, and in that moment we saw that "litigating attorneys were the elusive customer segment that we had heretofore not thoroughly considered" (page 70). They had never been on our list. They filled the hall for thirty years.
"For which of you, desiring to build a tower, doesn't first sit down and count the cost, to see if he has enough to complete it? Or perhaps, when he has laid a foundation and isn't able to finish, everyone who sees begins to mock him, saying, 'This man began to build and wasn't able to finish.' Or what king, as he goes to encounter another king in war, will not sit down first and consider whether he is able with ten thousand to meet him who comes against him with twenty thousand? Or else, while the other is yet a great way off, he sends an envoy and asks for conditions of peace." (Luke 14:28-32)
The dinner is over. Great multitudes are going with Jesus now, out on the road, and he turns and gives them the least promotional speech in the history of recruiting. Twice in four verses he says the same thing. Sit down first.
The tower builder is every one of us who has ever drawn up a plan. Daniel Kahneman and Amos Tversky named the planning fallacy, our habit of forecasting from the best case and forgetting how things usually go. The cure is arithmetic, and it has two numbers. Your estimate is one. The other is the base rate: what happened to everyone who made such an estimate before you. Bent Flyvbjerg has spent his career collecting it, and his database of more than 16,000 projects says that 47.9 percent finished on budget, fewer than one in two; 8.5 percent on budget and on time, about one in twelve; and 0.5 percent on budget, on time and with the benefits promised, one in two hundred. So count the cost from the base rate, not from the plan. Out of two hundred towers like yours, about 104 will miss the budget, 183 will miss the budget or the date, and 199 will miss something. Yours may be the one. The counting starts from the two hundred. I can add a small tower to his database. At the Pump Room we sat down to dinner first and to count afterward, and the counting took a year and nearly everything we had.
The king's arithmetic is harder, and Luke supplies the numbers. In 1916 the English engineer Frederick Lanchester worked out what happens when two armies fire on each other until one is gone. Here is his rule, one step at a time. When every soldier can aim at any enemy, each side's losses run at a rate set by the other side's size: an army of 20,000 kills twice as fast as an army of 10,000. But the larger army is also twice as big, so each of its men is thinned at half the rate. Twice the fire and half the thinning, together: four times the strength. Lanchester's square law says it in one line: an army's fighting strength is its numbers squared. Ten thousand squared is 100 million; twenty thousand squared is 400 million; the fight is four to one, not two to one. In symbols, with A and B the two armies, A falls at a rate k x B and B at a rate k x A, and from that it follows that A2 - B2 never changes during the battle. That also tells you how it ends. When the smaller army reaches zero, the larger still has 400 million minus 100 million, 300 million, and the square root of 300 million is its survivors: about 17,321 of the 20,000. Picture the king's council: the map unrolled, the generals talking of courage, one old counselor doing the sum. If the soldiers are equally good, the king's ten thousand are destroyed, and the other side loses only about 2,679 men doing it. Ten thousand lives, for 2,679. To fight evenly, each of the king's soldiers would have to be four times as good as each of the enemy's. So, while the other army is still a great way off, the king sends an envoy. In this story peace is the fruit of honest arithmetic done early.
The lesson is older than Lanchester and plainer than his equation. If you are the challenger, never meet a bigger army along the whole front, because numbers count twice; pick the one narrow place where your soldiers are four times as good, or send the envoy while you still can and take terms you could never get after the battle. If you are the incumbent, your advantage is larger than it looks, and it comes from concentration, so do not scatter it: a giant that spreads itself over ten fronts is ten small armies. And if you are an investor judging a small company's attack on a giant, ask the counselor's question before you listen to the generals: where is the narrow front, and are the soldiers really four times as good there? If the plan is to take the giant on everywhere at once with better spirit, the square law has already written the ending.
Then the hardest verse in the chapter: "whoever of you who doesn't renounce all that he has, he can't be my disciple." Jesus does not hide the price. He is the only recruiter I know who stopped a crowd already following him to tell it what following would cost. And the chapter ends with the line every prospectus ought to carry: "He who has ears to hear, let him hear."
A sermon should change what you do on Monday morning, and so should an essay. Here is what Luke 14 has changed in how I invest and how I work. None of it is advice to buy or sell anything. All of it is arithmetic you can do yourself.
For the portfolio, four questions, one for each course but the third, which refuses to be a question.
The watchers. Who is watching this company? When it is under siege, from a short seller, a regulator or a lawsuit, I check whether its peers are held to the same rule. If the watchers have never taken yes for an answer, the fault may measure the watching more than the company. If they have, I listen; Wirecard's watchers were right. And when a rule is the company's advantage, a license its rivals cannot get, a standard written around its product, a tariff that keeps the cheaper import out, I ask what is left without the rule. That is Stigler's lesson read the other way. A rule the industry acquired from its watchers is a moat made of paper: the watchers can be replaced by a new administration, overruled by a court or won over by a rival, and a moat made of rules is only as durable as the rule. So I value an advantage of that kind as a lease with a term, never as land the company owns.
The seats. Which seat has management chosen? I take the growth the company forecast at the start of each of the past three years and set it beside the growth it actually delivered, because the gap between the two is the seat it chose. A company that guides low and beats has taken the lowest place and waited for "Friend, move up higher." One asked to move down three times in a year has not, and because a loss stings more than twice as much as a gain, the market charges more for each move down than it ever paid for a move up.
The great supper. Whom is it serving that nobody invited? The best growth I have seen came from the hedges, from customers the established firms never courted. And when a whole room says the same thing at once, I remember that sixty excuses began with three, and I ask who went first.
Counting the cost. Before I believe a company's plan, I ask the two questions the chapter asks. The tower builder's first: how do plans like this usually turn out? Fewer than half of big projects come in on budget, so I start from that base rate and not from the plan, and I remember that my own first company was in the larger half. Then the king's: how big is the other army? When a small company announces that it will take on a giant across the whole market, I do the counselor's sum, twice the size is four times the strength, and I look for the narrow front where its soldiers are better. If I cannot find one, I expect an envoy, which in business means a sale, a partnership or a retreat, and I would rather see it sent while the other army is still a great way off.
And for the rest of Monday, three habits.
Ask your own hardest question out loud before your critics do, as Jesus did with the sick man before him. It costs a moment of discomfort and springs the trap before it closes.
Take the lower seat: in your forecasts, your negotiations, your introductions. Let yourself be invited up.
And the third course, which would not be a question: once a month, give something to someone who cannot repay you, an hour, a lunch, an introduction. It will not show on any statement. That is the point.
Here is all I am really saying. The arithmetic in this sermon explains the guests: why the watchers watch, why the proud take the top seat, why sixty men refuse at once, why a king counts before he fights. It does not explain the host, who fills his hall with people who can never pay him back. No model I own has a column for that, which is why the third course is a habit and not a question.
So here is my one request, and it costs an evening. Read the Gospel of Luke: chapter 14, and then chapter 15, where a father sees his son "while he was still far off," and runs to meet him and throws a feast. I came to that table late, by way of Hebrew School and many years of unbelief, and I will say plainly what no arithmetic can: I believe the host is real. Count the cost, as Jesus asks. And if it comes out, as it did for me, in favor of the dinner, you will hear the servant's words the way I hear them now: "Come, for everything is ready now." There is still room.
