1 Corinthians 9:20-23
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 law (though I myself am not under the law) so that I might win those under the law. 21 To those outside the law I became as one outside the law (though I am not free from God’s law but am under Christ’s law) so that I might win those outside the law. 22 To the weak I became weak, so that I might win the weak. I have become all things to all people, that I might by all means save some. 23 I do it all for the sake of the gospel, so that I may share in its blessings.
