1 Corinthians 9:21-25

To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law.

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

And this I do for the gospel’s sake, that I might be partaker thereof with you.

Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain.

And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.
