24 Don't you realize that in a race everyone runs, but only one person gets the prize? So run to win! 25 All athletes are disciplined in their training. They do it to win a prize that will fade away, but we do it for an eternal prize. 26 So I run with purpose in every step. I am not just shadowboxing. 27 I discipline my body like an athlete, training it to do what it should. Otherwise, I fear that after preaching to others I myself might be disqualified.

Commentary on 1 Corinthians 9:24-27

(Read 1 Corinthians 9:24-27)

The apostle compares himself to the racers and combatants in the Isthmian games, well known by the Corinthians. But in the Christian race all may run so as to obtain. There is the greatest encouragement, therefore, to persevere with all our strength, in this course. Those who ran in these games were kept to a spare diet. They used themselves to hardships. They practised the exercises. And those who pursue the interests of their souls, must combat hard with fleshly lusts. The body must not be suffered to rule. The apostle presses this advice on the Corinthians. He sets before himself and them the danger of yielding to fleshly desires, pampering the body, and its lusts and appetites. Holy fear of himself was needed to keep an apostle faithful: how much more is it needful for our preservation! Let us learn from hence humility and caution, and to watch against dangers which surround us while in the body.
