Origen, on Rom 5:20

“Now the law entered in, that sin might abound. And where sin abounded, grace did more abound.”

“What Paul means here is that after the natural law had already been established—the law which he calls the law of the mind, which assents to the law of God—another law arose, the law of our members, which promotes the lusts of the flesh and leads men captive, inclining them to desire and excesses, so that sin may abound in them.…Grace abounded all the more, because not only does it absolve us from the sins which we have already committed, it protects us against sinning in the future.”
