As both a Christian and a neuroscientist, Dr. Stanford has seen scientific knowledge distorted to justify sinful behavior and perhaps more disturbingly, he has seen Christians misuse Scripture to demonize and alienate the very ones they should be reaching out to. He suggests that the underlying cause of this problem in the church is a lack of knowledge, both of basic brain function and scriptural teaching.The Biology of Sin discusses sinful behaviors, including adultery, rage, addiction, and homosexuality, asking of each: What does science say, and what does the Bible say about this behavior? He then attempts to reconcile the fact that biological predispositions do play a role in behavior which the Bible defines as sinful while always emphasizing the authority of God's Holy Word and the abundant grace he has for those struggling with habitual sin.
