QUOTE : critics often dismiss Christianity as irrational—yet it does not require any irrational, self-contradictory leap of faith. Because it begins with a personal God, Christianity provides a consistent, unified worldview that holds true both in the natural realm and in the moral, spiritual realm. The biblical doctrine of the image of God gives a solid basis for human dignity and moral freedom that is compatible with the compelling witness of human experience. Unlike the evolutionary psychologist, Christians can live consistently on the basis of their worldview because it fits the real world.
