The commonest question is whether I really “believe in the Devil.” Now if by “the Devil” you mean a power opposite to God and, like God, self-existent from all eternity, the answer is certainly “No.” There is no uncreated being except God. God has no opposite. No being could attain a “perfect badness” opposite to the perfect goodness of God; for when you have taken away every kind of good thing (intelligence, will, memory, energy, and existence itself) there would be none of him [Satan] left.
~C.S. Lewis — for reflection on Job 1:6-12
