John Piper, Tim Keller, and Don Carson talk about growing older, making transitions, and pastoral succession.
Note that Piper told the people of Bethlehem last Sunday:
My proposal to the elders—and it comes from Noël and me, not just me (we have talked a lot about this, as you can imagine)—is that I transition from pastor for preaching and vision to a fulltime writing and BCS [Bethlehem College and Seminary] teaching and mentoring and wider speaking role on June 30, 2014—three years from now. And that we be very intentional and prayerful and thoughtful about a successor in those years.
That’s not the plan yet, because the elders have to think through all the implications and come to a mind.
The Gospel Coalition looked at this issue in a profile on “Gospel Integrity and Pastoral Succession,” which includes an explanation of what Keller and Redeemer plan to do.
