Hey,
I find these books a great help as an evangelising tool, to give out to my friends after i've had a chat to them about God and JC.
They're pretty cheap, and the answer the questions.
(the case for christ is the best one to give out i think because its christ who saves not if they understanding why evil is in the world etc).
So heads up about those if you wanna us them as a tool, I recommend you do. I personally really sell the fact that Strobel was an atheist and wanted to disprove Christianity because his wife became Christian, and the fact that he was a law journalist and so goes about it objectively, if not subjectively from an atheist pov. And people are more likely to read it knowing that the author isn't 'another christian trying to sell christianity'.
Plus its a good book for sources in essay etc. (if you do philosophy;religion, or anthorp) Hope it helps. Anyone else read them??
