Here is the Nov. 1, 2009 White Horse Inn interview with Tim Keller. The subject was Keller’s New York Times best seller The Reason for God. There are some fascinating thoughts on evangelism and skepticism in New York. Keller gives some very helpful thoughts about the need for a more robust theological and confessional approach to ministry that is equally culturally engaging.

I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
