From Tim Stafford's bio on (and interview with) Tim Keller in Christianity Today...
Keller is the long-time minister at Redeemer Presbyterian in uptown Manhattan. Beyond his multi-side church and numerous church plants, he and his crew are looking to extend their model beyond NYC.
Standing 6'4", with a bald head, glasses, and a coat and tie, Keller, 58, does not look hip. Nor is his sermon funny, charming, or daring. He preaches from the first chapter of Genesis, on the doctrine of Creation. Keller speaks like a college professor, absorbed in his content, of which there is a lot....
Stafford then outlines the sermon:
Keller begins by saying that authorial intention is a key to interpreting any ancient text, and by that criterion, Genesis 1 is obviously not about evolution. Keller explains the literary principles scholars use to argue whether Genesis 1 is poetry or historical narrative. If poetry, then its six "days" may be poetically long; if historical narrative, it speaks of a young earth. Keller says he believes Genesis 1 is Hebrew poetry (though Genesis 2 is not), but pleads for mutual forbearance. "Christians used to agree to disagree on this," he urges.
He goes on to preach four points of doctrine: the goodness of creation, the finiteness of creation, the unity of creation, and the importance of creation. His audience is dead silent, apparently rapt. Citing Jonathan Edwards, Elisabeth Elliot, J. R. R. Tolkien, Richard Dawkins, and John Updike, he fills out the richness of doctrine. Along the way, for each of his four points, he manages to appeal to nonbelievers....
Keller closes by asking: "Why does nature move everybody?" Why may even the most hardened atheist find that a forest dawn prompts tears, laughter, or joy?...We are moved, Keller says, because we wish to join that chorus and cannot. He points to the Cross as the way by which we can regain that song.
Keller's final words: "Have you accepted Jesus into your life as your Creator?"
How did he (and his family) get there?
They had caught a vision for Manhattan as a place terribly underserved by the church, and a place with gigantic multipliers of influence throughout society. It was both needy and strategic.
Just as important, the Kellers discovered that they liked Manhattan....Tim found Manhattan non-Christians amazingly, sometimes naïvely, curious. Though the borough's 1.6 million people were used to religious diversity, many had never talked to an evangelical. Tim's interest in art and music was an indispensable gift in communicating. His omnivorous reading also helped....
The Kellers stick to a few rules. They never talk about politics. Tim always preaches with a non-Christian audience in mind, not merely avoiding offense, but exploring the text to find its good news for unbelievers as well as believers. The church emphasizes excellence in music and art...And it calls people to love and bless the city....
Now what?
What has Redeemer accomplished after 20 years? Keller pauses. "We have a beachhead...."
White believes Keller's unique gift is to preach to both Christians and non-Christians in the same terms, without making a choice between evangelism and discipleship...A theology of grace uses the same language to challenge both the runaway son and the solid older brother....
Of the 65 churches that Redeemer has helped to plant in the New York area, only 10 are PCA. The largest is Southern Baptist. Pastor Gyger puts it this way: "He has a practical understanding that if we are going to reach the whole city, we need a wide spectrum of the church."
Much of Redeemer's impact has been through friendships, word of mouth, and sermons passed on from one person to another. Redeemer resisted publicity, avoiding reporters. For years, Keller did little writing or speaking outside the church. But now Keller is writing and speaking extensively, and has also put formal mentoring programs in place....
