Amazingly, reason cannot stand on its own. An unbounded reason often turns into a bone-crushing monster. For example, in some cultures it is reasonable to euthanize the mentally handicapped, or treat women as less than fully human. So, reason needs faith. The problem is that our Post-Cartesian society has made us swallow the blue pill of blindness, of blind faith. Jesus Christ offers us the red pill of reality, reality filled with truth, meaning, and grace. Let me show you some ways that faith informs Christian reasoning.
