1 Corinthians 9:23

21to those who are without law, as without law (not being without law toward God, but under law toward Christ), that I might win those who are without law.

22To the weak I became as weak, that I might gain the weak. I have become all things to all men, that I may by all means save some.

23Now I do this for the sake of the Good News, that I may be a joint partaker of it.

24Don’t you know that those who run in a race all run, but one receives the prize? Run like that, so that you may win.

25Every man who strives in the games exercises self-control in all things. Now they do it to receive a corruptible crown, but we an incorruptible.
