1 Corinthians (1 Co) 9:19-23

For although I am a free man, not bound to do anyone’s bidding, I have made myself a slave to all in order to win as many people as possible. That is, with Jews, what I did was put myself in the position of a Jew, in order to win Jews. With people in subjection to a legalistic perversion of the Torah, I put myself in the position of someone under such legalism, in order to win those under this legalism, even though I myself am not in subjection to a legalistic perversion of the Torah. With those who live outside the framework of Torah, I put myself in the position of someone outside the Torah in order to win those outside the Torah — although I myself am not outside the framework of God’s Torah but within the framework of Torah as upheld by the Messiah. With the “weak” I became “weak,” in order to win the “weak.” With all kinds of people I have become all kinds of things, so that in all kinds of circumstances I might save at least some of them. But I do it all because of the rewards promised by the Good News, so that I may share in them along with the others who come to trust.
