"For instance, one middle-aged candidate didn't pass his denomination's assessment process; they thought he was too introverted and couldn't engage unchurched people. (They also rated him as a 'mediocre preacher'.) Upon further prayer and conversation, they revised that decision. He went on to plant a thriving church in the northeast. Today this pastor has launched an entire network of dynamic new church starts. That's the story of the introverted, bookish, 'mediocre preacher' named Tim Keller [pastor of the 5,000+ Redeemer in NYC]."
