thanks for the blog, i've been following it for a month or so now and it's been interesting and encouraging a number of times. I was recently struck by a verse in Mark 2 with regards to the idea of Jesus being just a good teacher and wrote it up here:

May or may not be useful but my meanderings almost inevitably ended up at CS Lewis' mad, bad or god trilemma. I think that is a good way to go when considering this question... If you did go down this route it might be interesting to go further and respond to the criticism of Lewis' construct, that the biblical Jesus isn't historical (i.e. the claim that the trilemma is false, and there are 4 choices - Liar, Lunatic, Lord or Legend). Not given it much thought, but i think there must a pretty solid response that can be constructed to show that "legend" really doesn't carry the same weight as an option for consideration - when looking at Gospel correlation, historical evidence outside of the bible, early gospel manuscripts to show that Jesus' claims of Deity were not later additions, etc.
