In this brief interview, Tim Keller offers some advice on prayer, gospel-centered contextualization, a new writing project, and the new breadth and balance of city centre churches. To get you going, here is his comment on contextualization:

The gospel is the key. If you don’t have a deep grasp on the gospel of grace, you will either over-contextualize because you want so desperately to be liked and popular, or you will under-contextualize because you are self-righteous and proud and so sure you are right about everything. The gospel makes you humble enough to listen and adapt to non-believers, but confident and happy enough that you don’t need their approval.
