Augustine of Hippo, on 1Cor 15:56

“Now the sting of death is sin: and the power of sin is the law.”

“Indeed, by sinning we slip down into death. For where the law forbids, we sin more seriously than if we were not forbidden by the law. However, when grace is added, we then fulfill without difficulty and most willingly that very thing which the law had oppressively commanded. We are no longer slaves of the law through fear but friends through love and slaves of the righteousness which was the very source of the law's promulgation. Accordingly the law of sin and death, that is, the law imposed upon sinning and dying men, merely commands that we do not covet. Nonetheless, we do covet. However, the law of the spirit of life—the law which belongs to grace and sets us free from the law of sin and death—causes us not to covet. It causes us to fulfill the commands of law.”
