1 Corinthians 9:25-27

RKJNT(i) 25 And every man who competes is temperate in all things. Now they do it to obtain a perishable crown; but we an imperishable. 26 Therefore, I do not run aimlessly; and I do not fight as one who beats the air: 27 But I beat my body, and bring it into subjection: lest by any means, when I have preached to others, I myself should be disqualified.
