1 Corinthians 9:19-23

And I declare I carry that principle through all that I do. I absolutely neglect my own point of view. Other people’s opinions, other people’s beliefs and creeds and traditions, other people’s weaknesses — these all become my own. The freer I am myself, the more I seem to become the slave of others! And though this is past a joke, yet I do it willingly, because thereby I win people. At one time the Jewish tradition and the law are everything to me — that is because I am with Jews. And now they are nothing to me — because I am with Gentiles. Oh yes, the law is something to me, the divine law, Christ’s laws I mean, but not the law of the Jews. But with the weak I become weak myself — all things to all men in fact, if only I can win a few. And why do I do all this? Why do I take everybody else’s point of view except my own? For the sake of the Gospel, because I wish to have a share in it myself — on just the same principle as the athlete trains for a contest.
