1 Corinthians 9:21-23

21To those who are without (outside) the Law, [I became] as one without the Law, though [I am] not without the law of God, but under the law of Christ, so that I might win those who are without law.

22To the weak I became [as the] weak, to win the weak. I have become all things to all men, so that I may by all means [in any and every way] save some [by leading them to faith in Jesus Christ].

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