Romans 5:15

5:15 But the gracious gift is not like the transgression. For if the many died through the transgression of the one man, how much more did the grace of God and the gift by the grace of the one man Jesus Christ multiply to the many!

Romans 7:7

7:7 What shall we say then? Is the law sin? Absolutely not! Certainly, I would not have known sin except through the law. For indeed I would not have known what it means to desire something belonging to someone else if the law had not said, “Do not covet.”
