I'm now reading George Ladd's excellent The Gospel of the Kingdom. This fall at my church I'll be teaching this on eight Sunday evenings out of this text. I began reading it this week and found I could not put it down. One reason for this is that since last September I have been preaching and teaching the 4 Gospels on Sunday mornings . And I began reading and re-reading through Matthew, Mark, Luke and John last September, and will continue doing this for at least another year. So I am immersed in Jesus-studies. I want to know Jesus, the Real Jesus. Ladd's work is extremely helpful, since Jesus' main message was "Repent, for the Kingdom of heven is near."
I also picked up John Howard Yoder's classic The Politics of Jesus, and will begin reading that very soon.
