1 Corinthians 9:20-24

To the Jews I became as a Jew, so that I might gain Jews; to those who are under the Law, I became as one under the Law, though not being under the Law myself, so that I might gain those who are under the Law;

to those who are without the Law, I became as one without the Law, though not being without the law of God but under the law of Christ, so that I might gain those who are without the Law.

To the weak I became weak, that I might gain the weak; I have become all things to all people, so that I may by all means save some.

I do all things for the sake of the gospel, so that I may become a fellow partaker of it.

Do you not know that those who run in a race all run, but only one receives the prize? Run in such a way that you may win.
