1 Corinthians 9:19-22

19For though I am free from all men, yet I have made myself servant to all, that I might gain the more. 20And to the Jews I became as a Jew, that I might gain the Jews; to them that are under the law, as under the law, that I might gain them that are under the law; 21To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law. 22To the weak I became as weak, that I might gain the weak: I have become all things to all men, that I might by all means save some.
