1 Corinthians 9:24-27

“Don’t you know that those who run in a race all run, but one receives the prize? Run like that, that you may win. 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. I therefore run like that, not aimlessly. I fight like that, not beating the air, 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.”
