When I break God’s law, I stand above God’s law, and I feel like I am God, the one in control. Seeing myself as one who lives under the law is a constant reminder to me that I am not God but a creature, subject to his rule. The sheer delight Augustine found in stealing the mediocre and bitter pears was not a delight in the intrinsic merits of pears themselves. It was the pleasure of pretending to himself that he was God.
