1 Corinthians 9:20-22

To the Jews I became like a Jew, to win Jews; to those under the law, like one under the law — though I myself am not under the law  — to win those under the law. To those who are without the law, like one without the law — though I am not without God’s law but under the law of Christ — to win those without the law. To the weak I became weak, in order to win the weak. I have become all things to all people, so that I may by every possible means save some.
