Tim Keller shares this illustration in his new book, Encounters with Jesus: Unexpected Answers to Life’s Biggest Questions (Dutton; 2013), 28–30:
Everybody has got to live for something, but Jesus is arguing that, if he is not that thing, it will fail you.
First, it will enslave you. Whatever that thing is, you will tell yourself that you have to have it or there is no tomorrow. That means that if anything threatens it, you will become inordinately scared; if anyone blocks it, you will become inordinately angry; and if you fail to achieve it, you will never be able to forgive yourself.
But second, if you do achieve it, it will fail to deliver the fulfillment you expected.
Let me give you an eloquent contemporary expression of what Jesus is saying. Nobody put this better than the American writer and intellectual David Foster Wallace. He got to the top of his profession. He was an award-winning, best-selling postmodern novelist known around the world for his fierce and boundary-pushing storytelling. He once wrote a sentence that was more than a thousand words long. And, tragically, he committed suicide. But a few years before that, he gave a now-famous commencement speech at Kenyon College. He said to the graduating class,
Everybody worships. The only choice we get is what to worship. And the compelling reason for maybe choosing some sort of god . . . to worship . . . is that pretty much anything else you worship will eat you alive. If you worship money and things, if they are where you tap real meaning in life, then you will never have enough, never feel you have enough. It’s the truth. Worship your own body and beauty and sexual allure, and you will always feel ugly. And when time and age start showing, you will die a million deaths before [your loved ones] finally plant you. . . . Worship power, and you will end up feeling weak and afraid, and you will need ever more power over others to numb you to your own fear. Worship your intellect, being seen as smart, you will end up feeling stupid, a fraud, always on the verge of being found out. Look, the insidious thing about these forms of worship is not that they are evil or sinful; it is that they’re unconscious. They are default settings.
Wallace was by no means a religious person, but he understood that everyone worships, everyone trusts in something for their salvation, everyone bases their lives on something that requires faith. A couple of years after giving that speech, Wallace killed himself. And this non-religious man’s parting words to us are pretty terrifying: “Something will eat you alive.”
Because even though you might never call it worship, you can be absolutely sure you are worshiping and you are seeking. And Jesus says, unless you’re worshiping me, unless I’m the center of your life, unless you’re trying to get your spiritual thirst quenched through me and not through these other things, unless you see that the solution must come inside rather than just pass by outside, then whatever you worship will abandon you in the end.
