But I keep under my {t} body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be {u} a castaway.

(t) The old man which strives against the Spirit.

(u) Or, reproved. And this word reproved is not contrasted with the word elect, but with the word approved, when we see someone who is experienced not to be such a one as he ought to be.

People's New Testament

9:27 But I keep under my body. I buffet my body (Revised Version). He puts the body down by his blows, by self denial for Christ.

And bring it into subjection. Into bondage (Revised Version). It shall not be his master, but his servant.

Lest... I myself should be a castaway. He keeps it under lest, after having preached to others, he should be rejected (Revised Version); that is, refused the prize of the crown. What an exhortation to us is this example of the apostle! Continually vigilant lest he should be finally rejected! Even he worked out his salvation with fear and trembling (Php 2:12). Surely, he should give all diligence to make our calling and election sure (2Pe 1:10). In this worldly, self-seeking, luxurious age we should give the more earnest heed to the things which we have heard (Heb 2:1).

Wesley's Notes

9:27 But I keep under my body - By all kinds of self denial. And bring it into subjection - To my spirit and to God. The words are strongly figurative, and signify the mortification of the body of sin, by an allusion to the natural bodies of those who were bruised or subdued in combat. Lest by any means after having preached - The Greek word means, after having discharged the office of an herald, (still carrying on the allusion,) whose office it was to proclaim the conditions, and to display the prizes. I myself should become a reprobate - Disapproved by the Judge, and so falling short of the prize. This single text may give us a just notion of the scriptural doctrine of election and reprobation; and clearly shows us, that particular persons are not in holy writ represented as elected absolutely and unconditionally to eternal life, or predestinated absolutely and unconditionally to eternal death; but that believers in general are elected to enjoy the Christian privileges on earth; which if they abuse, those very elect persons will become reprobate. St. Paul was certainly an elect person, if ever there was one; and yet he declares it was possible he himself might become a reprobate. Nay, he actually would have become such, if he had not thus kept his body under, even though he had been so long an elect person, a Christian, and an apostle.

Scofield Reference Notes

[1] castaway

Gr. adokimos, "disapproved." Dokimos, without the private a, is translated "approved" in Rom 14:18 16:10 1Cor 11:19 2Cor 10:18 2Tim 2:15 Jas 1:12, by the word "tried." The prefix simply changes the word to a negative, i.e. not approved, or, disapproved. The apostle is writing of service, not of salvation. He is not expressing fear that he may fail of salvation but of his crown. See "Rewards" Dan 12:3 1Cor 3:14.

Jamieson-Fausset-Brown Bible Commentary

27. keep under-literally, "bruise the face under the eyes," so as to render it black and blue; so, to chastise in the most sensitive part. Compare "mortify the deeds of the body," Ro 8:13; also 1Pe 2:11. It is not ascetic fasts or macerations of the body which are here recommended, but the keeping under of our natural self-seeking, so as, like Paul, to lay ourselves out entirely for the great work.

my body-the old man and the remainders of lust in my flesh. "My body," so far as by the flesh it opposes the spirit [Estius] (Ga 5:17). Men may be severe to their bodies and yet indulge their lust. Ascetic "neglect of the body" may be all the while a more subtile "satisfying of the flesh" (Col 2:23). Unless the soul keep the body under, the body will get above the soul. The body may be made a good servant, but is a bad master.

bring it into subjection-or bondage, as a slave or servant led away captive; so the Greek.

preached-literally, "heralded." He keeps up the image from the races. The heralds summoned the candidates for the foot race into the race course [Plato, Laws, 8.833], and placed the crowns on the brows of the conquerors, announcing their names [Bengel]. They probably proclaimed also the laws of the combat; answering to the preaching of the apostles [Alford]. The The Christian herald is also a combatant, in which respect he is distinguished from the herald at the games.

a castaway-failing shamefully of the prize myself, after I have called others to the contest. Rejected by God, the Judge of the Christian race, notwithstanding my having, by my preaching, led others to be accepted. Compare the equivalent term, "reprobate," Jer 6:30; 2Co 13:6. Paul implies, if such earnest, self-denying watchfulness over himself be needed still, with all his labors for others, to make his own calling sure, much more is the same needed by the Corinthians, instead of their going, as they do, to the extreme limit of Christian liberty.

Matthew Henry's Concise Commentary

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.
