1 Corinthians 9:24-27

Don’t you realize that everyone who runs in a race runs to win, but only one runner gets the prize? Run like them, so that you can win. Everyone who enters an athletic contest goes into strict training. They do it to win a temporary crown, but we do it to win one that will be permanent. So I run—but not without a clear goal ahead of me. So I box—but not as if I were just shadow boxing. Rather, I toughen my body with punches and make it my slave so that I will not be disqualified after I have spread the Good News to others.
