For he must reign He proves that the time is not yet come when Christ will deliver up the kingdom to the Father, with the view of showing at the same time that the end has not yet come, when all things will be put into a right and tranquil state, because Christ has not yet subdued all his enemies. Now that must be brought about, because the Father has placed him at his right hand with this understanding, that he is not to resign the authority that he has received, until they have been subdued under his power. And this is said for the consolation of the pious, that they may not be impatient on account of the long delay of the resurrection. This statement occurs in Psalm 110:1 Paul, however, may seem to refine upon the word until beyond what the simple and natural meaning of the word requires; for the Spirit does not in that passage give intimation of what shall be afterwards, but simply of what must be previously. I answer, that Paul does not conclude that Christ will deliver up the kingdom to the Father, on the ground of its having been so predicted in the Psalm, but he has made use of this quotation from the Psalm, for the purpose of proving that the day of delivering up the kingdom had not yet arrived, because Christ has still to do with his enemies. Paul, however, explains in passing what is meant by Christ's sitting at the right hand of the Father, when in place of that figurative expression he makes use of the simple word reign. The last enemy -- death We see that there are still many enemies that resist Christ, and obstinately oppose his reign. But death will be the last enemy [1] that will be destroyed. Hence Christ must still be the administrator of his Father's kingdom. Let believers, therefore, be of good courage, and not give up hope, until everything that must precede the resurrection be accomplished. It is asked, however, in what sense he affirms that death shall be the last enemy [2] that will be destroyed, when it has been already destroyed by Christ's death, or at least, by his resurrection, which is the victory over death, and the attainment of life? I answer, that it was destroyed in such a way as to be no longer deadly to believers, but not in such a way as to occasion them no uneasiness. The Spirit of God, it is true, dwelling in us is life; but we still carry about with us a mortal body. (1-Peter 1:24.) The substance of death in us will one day be drained off, but it has not been so as yet. We are born again of incorruptible seed, (1-Peter 1:23,) but we have not yet arrived at perfection. Or to sum up the matter briefly in a similitude, the sword of death which could penetrate into our very hearts has been blunted. It wounds nevertheless still, but without any danger; [3] for we die, but by dying we enter into life. In fine, as Paul teaches elsewhere as to sin, (Romans 6:12,) such must be our view as to death -- that it dwells indeed in us, but it does not reign

1 - "It may not be improper to remark that there is an inaccuracy in our common version, which so vitiates its application that it does not seem to sustain the conclusion to which the Apostle had arrived. It was his purpose to establish the perfection of our Savior's conquest, the advancement of his triumphs, and the prostration of all enemies whatever beneath his power. Now to say that the last enemy that shall be destroyed is death,' by no means affords a proof of this position. Though death might be destroyed, and be the last enemy that shall be destroyed, it would not thence appear but that other enemies might remain not destroyed. But the proper rendering is, Death, the last enemy, should be destroyed.'" -- R. Hall's Works, (Loud. 1846,) volume 6. -- Ed.

2 - "Ultimum vero seu novissimum hostem cur vocat? Chrysostomus putat, quia ultimo accessit. Primus fuit Satan, solicitaris hominem ad pecca-tum. Alter voluntas hominis, sponte se a Deo avertens. Tentius pecca-tum. Quartus denique mors, superveniens peccato. Sed baud dubie Apostolus novissimum vocat duratione, respectu aliorum externorum hos-tium Ecclesiae, quos Christus in fine abolebit omnes. Postremo et mor-tem corporalem pellet, suscitando omnes ex monte: ut hoc mortale induat immortalitatem;" -- "But why does he call it (death), the latest or last enemy? Chrysostom thinks, because it came last. The first was Satan tempting man to sin. The second -- man's will, voluntarily turning aside from God. The third -- sin. Then at length the fourth -- death, following in the train of sin. There can be no doubt, however, that the Apostle calls it the last in respect of duration, in relation to the other external enemies of the Church, all of which Christ will in the end abolish. Last of all, he will drive away the death of the body, by raising up all from death, that this mortal may put on immortality." Fareus in loc. -- Ed.

For he must reign - It is fit, or proper (δει dei), that he should reign until this is accomplished. It is proper that the mediatorial kingdom should continue till this great work is effected. The word "must" here refers to the propriety of this continuance of his reign, and to the fact that this was contemplated and predicted as the work which he would accomplish. He came to subdue all his enemies; see -Psalm 2:6-10; or Psalm 110:1, "The Lord said unto my Lord, Sit thou at my right hand until I make thine enemies thy footstool." Paul, doubtless, had this passage in his eye as affirming the necessity that he should reign until all his foes should be subdued. That this refers to the Messiah is abundantly clear from Matthew 22:44-45.

For he must reign, etc. - This is according to the promise, Psalm 110:1 : "The Lord said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool." Therefore the kingdom cannot be given up till all rule and government be cast down. So that while the world lasts, Jesus, as the Messiah and Mediator, must reign; and all human beings are properly his subjects, are under his government, and are accountable to him.

For he must reign, till he hath put all enemies (k) under his feet.
(k) Christ is considered here as he appeared in the form of a servant, in which respect he rules the Church as head, and that because this power was given to him from his Father.

For he must reign,.... That is, Christ must reign; he is set as King over God's holy hill of Zion; he is King of saints; he is made and declared to be both Lord and Christ; he is exalted at the right hand of God as a Prince, where he sits and rules and reigns; and his sitting at God's right hand is here explained by his reigning, for reference is had to Psalm 110:1 he must reign because it is the unalterable will, and unchangeable decree and purpose of God, that he should reign; and because he has promised it, and prophesied of it; and because the state and condition of his people require it, who otherwise could not be saved, nor dwell safely: and so he must and will,
till he hath put all enemies under his feet; and made them his footstool; meaning either all the elect of God, who in a state of nature are enemies in their minds, by wicked works, to himself and to his Father; whom he conquers by his grace, subdues their rebellious wills, of enemies makes them friends, brings them to his feet, and to a subjection to his sceptre, to his Gospel and ordinances; and he must reign till he has brought every elect soul into such an obedience to himself: or rather antichrist and his followers, and all wicked and ungodly men, with Satan and his angels; who will be destroyed with the breath of his mouth, and the brightness of his coming; and will be cast down by him into hell, and there be ever objects of his wrath and vengeance: and till all this is done he must reign; not that he shall cease to reign afterwards, but that he shall reign notwithstanding these enemies of his and his people, who would not have him to reign over them; and will reign until they are subdued or destroyed; and when they are entirely vanquished and overcome, who can doubt of his reigning then? or what, or who will there be to hinder it? The Alexandrian copy, and others, read, "his enemies"; and so do the Syriac and Ethiopic versions.

must--because Scripture foretells it.

He must reign - Because so it is written. Till he - the Father hath put all his enemies under his feet. Psalm 110:1.
