1 Corinthians 9:21-23

21To those without the law I became like one without the law (though I am not outside the law of God but am under the law of Christ), to win those without the law. 22To the weak I became weak, to win the weak. I have become all things to all people so that by all possible means I might save some.

23I do all this for the sake of the gospel, so that I may share in its blessings.
