Endeavor to hate sin as much as you have hated God. What reason have we to bewail ourselves! None of us have ever yet hated sin so much as, naturally, we have hated God.

Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be. (Romans 8:7)

This enmity to God is the greatest folly and madness. The Scripture tells us, that sin is folly and madness; and certainly had man a clear prospect of this truth, which in his first apostasy he fell from, so that he could examine all his speculations, desires, motions, and actions by that rule, they would appear to him to be acts of a crazy and frantic mind. Therefore upon our return to God we have but a glimpse of this truth, how much, ashamed is man of the deformity of his actions from that rule; as a man that has been mad is of those pranks he played in his frenzy, after he is brought to his right wits. Hence repentance, which is always accompanied with a shame, is called μετάνοια, a return to our right wits.
