I've been told the same things about his books, but I haven't really had the time to read them. I did read books by Josh Mc Dowell and Lee Stroubel that were supposed to have the same effect (this was at the time when I was still trying to convince myself that I was still a Christain, meaning I would give the "benefit of the doubt" to any pro Christain book), and they too failed on the weight of their illogic and/or silliness (when I was reading The Case for Christ and the "Lunatic, Liar or Lord" scenario was given to be a proof that Jesus existed, I couldn't help but shake my head in disbelief [pun intended ] ).
Anyway, rem, keep us posted on the book. Who knows, maybe it might get better and you'll be converted to Christanity in the end.
