Romans 1:5

1:5 Through him we have received grace and our apostleship to bring about the obedience of faith among all the Gentiles on behalf of his name.

Romans 1:13-15

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. 1:14 I am a debtor both to the Greeks and to the barbarians, both to the wise and to the foolish. 1:15 Thus I am eager also to preach the gospel to you who are in Rome.
