From a Tim Keller sermon on 'the first shall be last':
There was once a young seminary graduate eager to preach his first sermon. He ascended the pulpit steps, sure his great learning would amaze the simple lay folk. Halfway through the sermon he realized he was making a hash of it. First the congregation lost what he was saying, then he lost what he was saying. At the end he climbed down from the pulpit crestfallen. An old Christian woman met him at the end and said "If you'd have gone up the way you came down, you'd have come down the way you went up."
