To confirm what he had said of this change,

I.He here tells them what had been concealed from or unknown to them till then - that all the saints would not die, but all would be changed. Those that are alive at our Lord's coming will be caught up into the clouds, without dying, Th1 4:11. But it is plain from this passage that it will not be without changing from corruption to incorruption. The frame of their living bodies shall be thus altered, as well as those that are dead; and this in a moment, in the twinkling of an eye, Co1 15:52. What cannot almighty power effect? That power that calls the dead into life can surely thus soon and suddenly change the living; for changed they must be as well as the dead, because flesh and blood cannot inherit the kingdom of God. This is the mystery which the apostle shows the Corinthians: Behold, I show you a mystery; or bring into open light a truth dark and unknown before. Note, There are many mysteries shown to us in the gospel; many truths that before were utterly unknown are there made known; many truths that were but dark and obscure before are there brought into open day, and plainly revealed; and many things are in part revealed that will never be fully known, nor perhaps clearly understood. The apostle here makes known a truth unknown before, which is that the saints living at our Lord's second coming will not die, but be changed, that this change will be made in a moment, in the twinkling of an eye, and at the sound of the last trump; for, as he tells us elsewhere, the Lord himself shall descend with a shout, with a voice of the archangel, and with the trump of God (Th1 4:16), so here, the trumpet must sound. It is the loud summons of all the living and all the dead, to come and appear at the tribunal of Christ. At this summons the graves shall open, the dead saints shall rise incorruptible, and the living saints be changed to the same incorruptible state, Co1 15:52.

II.He assigns the reason of this change (Co1 15:53): For this corruptible must put on incorruption, and this mortal must put on immortality. How otherwise could the man be a fit inhabitant of the incorruptible regions, or be fitted to possess the eternal inheritance? How can that which is corruptible and mortal enjoy what is incorruptible, permanent, and immortal? This corruptible body must be made incorruptible, this mortal body must be changed into immortal, that the man may be capable of enjoying the happiness designed for him. Note, It is this corruptible that must put on incorruption; the demolished fabric that must be reared again. What is sown must be quickened. Saints will come in their own bodies (Co1 15:38), not in other bodies.

III.He lets us know what will follow upon this change of the living and dead in Christ: Then shall be brought to pass that saying, Death is swallowed up in victory; or, He will swallow up death in victory. Isa 25:8. For mortality shall be then swallowed up of life (Co2 5:4), and death perfectly subdued and conquered, and saints for ever delivered from its power. Such a conquest shall be obtained over it that it shall for ever disappear in those regions to which our Lord will bear his risen saints. And therefore will the saints hereupon sing their epinikion, their song of triumph. Then, when this mortal shall have put on immortality, will death be swallowed up, for ever swallowed up, eis nikos. Christ hinders it from swallowing his saints when they die; but, when they rise again, death shall, as to them, be swallowed for ever. And upon this destruction of death will they break out into a song of triumph.

1.They will glory over death as a vanquished enemy, and insult this great and terrible destroyer: "O death! where is thy sting? Where is now thy sting, thy power to hurt? What mischief hast thou done us? We are dead; but behold we live again, and shall die no more. Thou art vanquished and disarmed, and we are out of the reach of thy deadly dart. Where now is thy fatal artillery? Where are thy stores of death? We fear no further mischiefs from thee, nor heed thy weapons, but defy thy power, and despise thy wrath. And, O grave! where is thy victory? Where now is thy victory? What has become of it? Where are the spoils and trophies of it? Once we were thy prisoners, but the prison-doors are burst open, the locks and bolts have been forced to give way, our shackles are knocked off, and we are for ever released. Captivity is taken captive. The imaginary victor is conquered, and forced to resign his conquest and release his captives. Thy triumphs, grave, are at an end. The bonds of death are loosed, and we are at liberty, and are never more to be hurt by death, nor imprisoned in the grave." In a moment, the power of death, and the conquests and spoils of the grave, are gone; and, as to the saints, the very signs of them will not remain. Where are they? Thus will they raise themselves, when they become immortal, to the honour of their Saviour and the praise of divine grace: they shall glory over vanquished death.

2.The foundation for this triumph is here intimated, (1.) In the account given whence death had its power to hurt: The sting of death is sin. This gives venom to his dart: this alone puts it into the power of death to hurt and kill. Sin unpardoned, and nothing else, can keep any under his power. And the strength of sin is the law; it is the divine threatening against the transgressors of the law, the curse there denounced, that gives power to sin. Note, Sin is the parent of death, and gives it all its hurtful power. By one man sin entered into the world, and death by sin, Rom 5:12. It is its cursed progeny and offspring. (2.) In the account given of the victory saints obtain over it through Jesus Christ, Co1 15:56. The sting of death is sin; but Christ, by dying, has taken out this sting. He has made atonement for sin; he has obtained remission of it. It may hiss therefore, but it cannot hurt. The strength of sin is the law; but the curse of the law is removed by our Redeemer's becoming a curse for us. So that sin is deprived of its strength and sting, through Christ, that is, by his incarnation, suffering, and death. Death may seize a believer, but cannot sting him, cannot hold him in his power. There is a day coming when the grave shall open, the bands of death be loosed, the dead saints revive, and become incorruptible and immortal, and put out of the reach of death for ever. And then will it plainly appear that, as to them, death will have lost its strength and sting; and all by the mediation of Christ, by his dying in their room. By dying, he conquered death, and spoiled the grave; and, through faith in him, believers become sharers in his conquests. They often rejoice beforehand, in the hope of this victory; and, when they arise glorious from the grave, they will boldly triumph over death. Note, It is altogether owing to the grace of God in Christ that sin is pardoned and death disarmed. The law puts arms into the hand of death, to destroy the sinner; but pardon of sin takes away this power from the law, and deprives death of its strength and sting. It is by the grace of God, through the redemption which is in Christ Jesus, that we are freely justified, Rom 3:24. It is no wonder, therefore, (3.) If this triumph of the saints over death should issue in thanksgiving to God: Thanks be to God, who giveth us the victory through Christ Jesus, our Lord, Co1 15:57. The way to sanctify all our joy is to make it tributary to the praise of God. Then only do we enjoy our blessings and honours in a holy manner when God has his revenue of glory out of it, and we are free to pay it to him. And this really improves and exalts our satisfaction. We are conscious at once of having done our duty and enjoyed our pleasure. And what can be more joyous in itself than the saints' triumph over death, when they shall rise again? And shall they not then rejoice in the Lord, and be glad in the God of their salvation? Shall not their souls magnify the Lord? When he shows such wonders to the dead, shall they not arise and praise him? Psa 88:10. Those who remain under the power of death can have no heart to praise; but such conquests and triumphs will certainly tune the tongues of the saints to thankfulness and praise - praise for the victory (it is great and glorious in itself), and for the means whereby it is obtained (it is given of God through Christ Jesus), a victory obtained not by our power, but the power of God; not given because we are worthy, but because Christ is so, and has by dying obtained this conquest for us. Must not this circumstance endear the victory to us, and heighten our praise to God? Note, How many springs of joy to the saints and thanksgiving to God are opened by the death and resurrection, the sufferings and conquests, of our Redeemer! With what acclamations will saints rising from the dead applaud him! How will the heaven of heavens resound his praises for ever! Thanks be to God will be the burden of their song; and angels will join the chorus, and declare their consent with a loud Amen, Hallelujah.

For this corruptible, etc. - Because flesh and blood cannot inherit glory; therefore, there must be a refinement by death, or a change without it.

The sting of death is sin,.... Death has a sting, and which was originally in it, and that is sin; sin is the cause of death, it is what has given rise and being to it; it entered into the world by it, and is supported in its empire through it; it gives it its resistless power, which reaches to all sorts of persons, young and old, rich and poor, high and low, bond and free; it gives it all its bitterness, agonies, and miseries; and it is by that it does all the hurt and mischief it does; and it may fitly be compared to a sting, for its poisonous and venomous nature:

and the strength of sin is the law; not that the law of God is sinful, or encourages sin: it forbids it under the severest penalty; but was there no law there would be no sin, nor imputation of it; sin is a transgression of the law: moreover, the strength of sin, its evil nature, and all the dreadful aggravations of it, and sad consequences upon it, are discovered and made known by the law; and also the strength of it is drawn out by it, through the corruption of human nature; which is irritated and provoked the more to sin, through the law's prohibition of it; and this is not the fault of the law, but is owing to the vitiosity of nature; which the more it is forbidden anything, the more desirous it is of it; to which may be added, that sin is the more exceeding sinful, being committed against a known law, and that of the great lawgiver, who is able to save and to destroy; whose legislative power and authority are slighted and trampled upon by it, which makes the transgression the more heinous; it is the law which binds sin upon a man's conscience, accuses him of it, pronounces him guilty, curses, condemns, and adjudges him to death for it.

put on--as a garment (Co2 5:2-3).

immortality--Here only, besides Ti1 6:16, the word "immortality" is found. Nowhere is the immortality of the soul, distinct from the body, taught; a notion which many erroneously have derived from heathen philosophers. Scripture does not contemplate the anomalous state brought about by death, as the consummation to be earnestly looked for (Co2 5:4), but the resurrection.
