In this outstanding defense of Christianity, the author compares and contrasts six methods of reasoning used by philosophers during the resurgence of evangelical beliefs in the latter half of the 20th century. He looks at the empirical, rational, presuppositional, mystical, existential and verificational methods that stimulate critical thought about God, as seen in the Jesus of history and in the teachings of Scripture. Originally published in 1976 by Moody Press.
