1 Corinthians 9:24-27

YLT(i) 24 have ye not known that those running in a race—all indeed run, but one doth receive the prize? so run ye, that ye may obtain; 25 and every one who is striving, is in all things temperate; these, indeed, then, that a corruptible crown they may receive, but we an incorruptible; 26 I, therefore, thus run, not as uncertainly, thus I fight, as not beating air; 27 but I chastise my body, and bring it into servitude, lest by any means, having preached to others—I myself may become disapproved.
