I am a debtor both to the Greeks and to the barbarians, both to the wise and to the foolish.

Romans 1:14


Now I am speaking to you Gentiles. Seeing that I am an apostle to the Gentiles, I magnify my ministry, if somehow I could provoke my people to jealousy and save some of them.

Romans 11:13-14


For since I am free from all I can make myself a slave to all, in order to gain even more people. To the Jews I became like a Jew to gain the Jews. To those under the law I became like one under the law (though I myself am not under the law) to gain those under the law. To those free from the law I became like one free from the law (though I am not free from God’s law but under the law of Christ) to gain those free from the law. To the weak I became weak in order to gain the weak. I have become all things to all people, so that by
all means I may save some.

I Corinthians 9:19-22
