1 Corinthians 9:19-27 - Paul's Work As An Apostle
19 For though I am free from all, yet I have made myself a servant to all, that I might gain the more. 20 And to the Jews I became as a Jew, that I might gain the Jews; that is, to those, who are under the law, as under the law, that I might gain those who are under the law: 21 and to those without the law as without the law, (not being without law to God, but under the law to Christ) that I might gain those who are without the law. 22 To the weak I became as the weak, that I might gain the weak: I became all things to all men, that I might by every means save some. 23 And this I do for the sake of the gospel, that I may be a fellow partaker of it.
24 Know ye not, that those, who run in a race, do all indeed run, but one only receiveth the prize? So run that ye may obtain. 25 And every one that enters the lists is temperate in all things: they indeed do it that they may receive a corruptible crown, but we an incorruptible one. 26 I therefore so run, not as unobserved: I so fight, not as one that beateth the air: 27 but I mortify my body and bring it into subjection, least after having preached to others, I myself should be rejected.
