I didn't go. But I watched the 2 hour show online, hosted by Martin Bashir.
I find the Kellers interview to be particularly interesting, unfortunately.
Cathy Keller apologized to Bashir for thinking he was trying to scoop a news when they first met. Her attempt to show genuine public apology seemed a bit - late.
Timothy Keller admitted that he was going to focus on building leaders. I remember David Wilkerson was doing the same thing, then he got into a fatal car accident.
I think it is a dangerous thought, to think oneself a leader to a point that one's main ministry is to produce more leaders. A serious question can be asked: How are you going to treat those new leaders, who are not of your "group", but have some fellowship with some of your "group". You may want to think you are training them, but they may think that they have been trained more elsewhere. I am aware that the usual solution to this is simply IGNORE THEM! Especially they don't behave like you trained them. But because the incentive is that they should be grateful to you for having the opportunity to be involved with your program, you have an excuse for ignoring them.
