1 Corinthians 9:19-21

Common(i) 19 For though I am free from all men, I have made myself a slave to all, that I might win the more. 20 To the Jews I became as a Jew, in order to win Jews; to those under the law I became as one under the lawthough not being myself under the lawso that I might win those under the law. 21 To those who are without law, I became as one without law, though not being without the law of God but under the law of Christ, so that I might win those who are without the law.
