(book my husband was given by his grandma, that I picked up and decided to read) Letters From A Skeptic, A Son Wrestles with His Father's Questions about Christianity by Dr. Gregory A. Boyd. It's so far about a son and father writing letters to each other about God, religion, and why believe. The son is a pastor (also a professor of theology at Bethel College) and the father is the skeptic... they both bring up good debates on why or why not to believe in some higher power...
