1 Corinthians 9:24-27

CAB(i) 24 Do you not know that those running in a stadium all run, but one receives the prize? So run, in order that you may win. 25 And everyone who competes exercises self-control in all things. Now they compete in order that they may receive a perishable crown, but we compete for an imperishable crown. 26 Therefore I run thus: not as without a goal, thus I box: not as one beating the air. 27 But I treat my body roughly, and I bring it into subjection, lest, having preached to others, I myself should become disqualified.
