Let's explore this by considering two related themes that arise from the same Christian root. The first is Paul's statement above. Here Paul in a single phrase repudiates an entire tradition of classical philosophy founded in Plato. For Plato, the problem of evil is a problem of knowledge. People do wrong because they do not know what is right. If they knew what was right, obviously, they would do it. But Paul denies that this is so. His claim is that even though he knows something is wrong, he still does it. Why? Because the human will is corrupt. The problem of evil is not a problem of knowledge but a problem of will.
