The book "I Don't Have Enough Faith to Be an Atheist" by Norman Geisler and Frank Turek argues that atheism requires more faith than Christianity. The authors defend the existence of a creator God based on scientific, philosophical, and historical evidence, including the cosmological argument, the teleological argument, the moral argument, and the historical reliability of the New Testament. They explore the nature of truth, the reliability of scripture, and the divinity of Jesus, arguing that faith in God is reasonable and that the Bible is the inerrant word of God.
