1 Corinthians 9:25-27 World English Bible (WEB)

25. Every man who strives in the games exercises self-control in all things. Now they do it to receive a corruptible crown, but we an incorruptible.

26. I therefore run like that, not aimlessly. I fight like that, not beating the air,

27. but I beat my body and bring it into submission, lest by any means, after I have preached to others, I myself should be rejected.
