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 7:13

7:13 Did that which is good, then, become death to me? Absolutely not! But sin, so that it would be shown to be sin, produced death in me through what is good, so that through the commandment sin would become utterly sinful.
