I am an Atheist and my friend is a Christian. We have made a deal that we will each read one book on the other's beliefs so we can try to convince the other? better understand? I am not sure. We want something that tries to "prove" to me there is a God, rather than 200 pages of "the Bible says this and this." I was raised Christian and have read the Bible from cover to cover so I know what it's about.
What book should I read? What should I suggest he read?
