The apostle compared himself to a man running in a race, straining every nerve to win the prize. “I therefore so run,” he says, “not as uncertainly; so fight I, not as one that beateth the air: but I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.” 1 Corinthians 9:26, 27. That he might not run uncertainly or at random in the Christian race, Paul subjected himself to severe training. The words, “I keep under my body,”(1 Corinthians 9:27) literally mean to beat back by severe discipline the desires, impulses, and passions. (AA 314.1) MC VC

Paul feared lest, having preached to others, he himself should be a castaway. He realized that if he did not carry out in his life the principles he believed and preached, his labors in behalf of others would avail him nothing. His conversation, his influence, his refusal to yield to self-gratification, must show that his religion was not a profession merely, but a daily, living connection with God. One goal he kept ever before him, and strove earnestly to reach—“the righteousness which is of God by faith.” Philippians 3:9. (AA 314.2) MC VC

Paul knew that his warfare against evil would not end so long as life should last. Ever he realized the need of putting a strict guard upon himself, that earthly desires might not overcome spiritual zeal. With all his power he continued to strive against natural inclinations. Ever he kept before him the ideal to be attained, and this ideal he strove to reach by willing obedience to the law of God. His words, his practices, his passions—all were brought under the control of the Spirit of God. (AA 314.3) MC VC
