RSV ~ 1 Corinthians 9 v19 - 27
19 For though I am free from all men, I have made myself a slave to all, that I might win the more.
20 To the Jews I became as a Jew, in order to win Jews; to those under the law I became as one under the law—though not being myself under the law—that I might win those under the law.
21 To those outside the law I became as one outside the law—not being without law toward God but under the law of Christ—that I might win those outside the law.
22 To the weak I became weak, that I might win the weak. I have become all things to all men, that I might by all means save some.
23 I do it all for the sake of the gospel, that I may share in its blessings.
24 Do you not know that in a race all the runners compete, but only one receives the prize? So run that you may obtain it.
25 Every athlete exercises self-control in all things. They do it to receive a perishable wreath, but we an imperishable.
26 Well, I do not run aimlessly, I do not box as one beating the air;
27 but I pommel my body and subdue it, lest after preaching to others I myself should be disqualified.
