1 Corinthians 9:19-25 Revised Standard Version Catholic Edition (RSVCE)
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.
