Romans 1:13

1:13 I do not want you to be unaware, brothers and sisters, that I often intended to come to you (and was prevented until now), so that I may have some fruit even among you, just as I already have among the rest of the Gentiles.

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.”
