Kevin DeYoung has a good interview with Andreas Kostenberger on the mission of the church here.

Among other things, DeYoung asks him,

• In a couple sentences, what is the mission of Jesus in the gospel of John? Is the mission of the disciples the same as Jesus’ mission?
• You argue that “[T]he Fourth Gospel does therefore not appear to teach the kind of ‘incarnational model’ advocated by Stott and others” (217). Why are you critical of this approach? What are the exegetical problems? Is there a way we should be “incarnational” in our ministry?
• You also say “the church ought to be focused in the understanding of its mission” (219). Why is this focus important? When it comes to the church’s mission, what should be the focus?

Check it out. It follows up his own post on Kostenberger from the day before.
