1 Corinthians 9:21-25 American Standard Version (ASV)

21. to them that are without law, as without law, not being without law to God, but under law to Christ, that I might gain them that are without law.

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

23. And I do all things for the gospel’s sake, that I may be a joint partaker thereof.

24. Know ye not that they that run in a race run all, but one receiveth the prize? Even so run; that ye may attain.

25. And every man that striveth in the games exerciseth self-control in all things. Now they do it to receive a corruptible crown; but we an incorruptible.
