The common worldview among atheists has a name—actually, a couple of names. It is variously called “physicalism,” “materialism,” or “naturalism,” since the basic concept asserts that reality consists of nothing but the physical, material world governed by nothing but natural law.

However it’s characterized, it’s a significant obstacle keeping many skeptics from taking Christianity seriously. But fortunately, we Christians have a powerful ally in our engagements with atheists: reality is on our side. In this presentation, Greg offers a critique of naturalism, developing three solid lines of reasoning to show naturalism’s inadequacy and Christianity’s superior “explanatory power” as a reliable guide to understanding the world.
