Simple questions they may be - but they are tough ones for any Christian to answer. This is a remarkably well written book by an atheist. The author doesn't want to pick a fight engage in argument. He just wants to have a conversation with Christians to explain why non-believers have difficulty accepting the claims and world view of Christians. The questions are explored with superb clarity and show a deep understanding of Christian thought. There is no sign of antagonism and the evidence and reasoning offered is compelling. The only (very minor) criticism is that I don't think the author's definition of irreducible complexity (an "intelligent design" concept) was accurate or fair. Apart from that, this book is a must read for anyone interested in Christian thought and the reasons for many people's genuinely held skepticism. ( )
