(10) When he shall come.--Not simply a repetition of the temporal date which was mentioned in 2Thessalonians 1:7--"when the Lord," &c--but an introduction of the contrast which will be presented "in that day" by the spectacle of the glory of the saints. Thus the penalty of 2Thessalonians 1:9 is made to appear greater, while at the same time the readers' minds are turned back to a more wholesome subject for meditation.

To be glorified in his saints.--This is not exactly the purpose, but the effect of His coming. A comparison of John 13:31-32; John 14:13; John 17:10; 2Thessalonians 1:12; shows that the saints are the objects on which and by which the glorious perfection of Christ is exhibited: to see what the saints will be exalted to "in that day" will make all observers acknowledge, not the holiness or greatness of the men, but the divine power of Him who was able so to exalt them. As the persecutors were divided into two classes to be punished, so the saved are described under two aspects: in contrast with "them that know not God" they are "saints," i.e., fully consecrated to God; in contrast with "them that obey not the gospel" they are "they that believed" (for the past tense is the better reading), i.e., accepted the gospel. As the profane Gentiles, looking on the saints, recognise the "glory" of the God whom they knew not, so the disobedient Jews, seeing the faithful, are aptly filled with "wonder" (Acts 13:41), before they perish, at the glory to be attained by obedience to the law of suffering.

Because our testimony.--Introduced to show why the writers had said specially "in all them that believed" (the past tense is employed because it looks back from the Judgment Day to the moment when the gospel was offered and the divergence between believers and unbelievers began); the reason was, because among "all them that believed" the Thessalonians would be found included.

In that day.--Added at the end to make the readers look once more (as it were) upon the wonderful sight on which the writer's prophetic eyes were raptly fixed.

Verse 10. - When; defining the period when this judgment of the wicked will occur. He; namely, the Lord Jesus. Shall come to be glorified; the purpose of his coming. In; not "through," or "among," but "in," as the sphere or element of his glory. His saints; not the holy angels who will accompany him to judgment, but holy men whom he has redeemed with his blood. Christ will be glorified in his saints, inasmuch as their glory was the result of his sufferings and death, and their holiness is the reflection of his holiness; "They will reflect as in a mirror the glory of the Lord." And to be admired; wondered at, praised. In all them that believe; or, believed. The work of faith is past; the result of faith, the state of sight and glory, has commenced. The glorification of believers will thus become the glorification of Christ. The glory of Christ does not arise from the punishment of the wicked, but from the glorification of believers. Christ will indeed be glorified in the punishment of the wicked. His justice will be manifested and vindicated; but his glory will be especially seen in the manifestation of his mercy toward believers. Because our testimony; namely, the testimony of Paul and his associates, Silas and Timothy. Among you; or rather, unto you. Was believed; to be considered as a parenthesis. In that day; namely, the day of the Lord's advent, to be connected with the commencement of the verse, "In that day when he shall come to be glorified in his saints." Some, overlooking the parenthesis, render the words either, "because our testimony concerning that day was believed among you;" or, "because our testimony among you shall be believed on that day" - assented to by the whole universe; but the first rendering gives a false meaning to the preposition, and the second a false construction to the verb, as if it were future.

1:5-10 Religion, if worth anything, is worth every thing; and those have no religion, or none worth having, or know not how to value it, cannot find their hearts to suffer for it. We cannot by all our sufferings, any more than by our services, merit heaven; but by our patience under sufferings, we are prepared for the promised joy. Nothing more strongly marks a man for eternal ruin, than a spirit of persecution and enmity to the name and people of God. God will trouble those that trouble his people. And there is a rest for the people of God; a rest from sin and sorrow. The certainty of future recompence is proved by the righteousness of God. The thoughts of this should be terrible to wicked men, and support the righteous. Faith, looking to the great day, is enabled partly to understand the book of providence, which appears confused to unbelievers. The Lord Jesus will in that day appear from heaven. He will come in the glory and power of the upper world. His light will be piercing, and his power consuming, to all who in that day shall be found as chaff. This appearance will be terrible to those that know not God, especially to those who rebel against revelation, and obey not the gospel of our Lord Jesus Christ. This is the great crime of multitudes, the gospel is revealed, and they will not believe it; or if they pretend to believe, they will not obey it. Believing the truths of the gospel, is in order to our obeying the precepts of the gospel. Though sinners may be long spared, they will be punished at last. They did sin's work, and must receive sin's wages. Here God punishes sinners by creatures as instruments; but then, it will be destruction from the Almighty; and who knows the power of his anger? It will be a joyful day to some, to the saints, to those who believe and obey the gospel. In that bright and blessed day, Christ Jesus will be glorified and admired by his saints. And Christ will be glorified and admired in them. His grace and power will be shown, when it shall appear what he has purchased for, and wrought in, and bestowed upon those who believe in him. Lord, if the glory put upon thy saints shall be thus admired, how much more shalt thou be admired, as the Bestower of that glory! The glory of thy justice in the damnation of the wicked will be admired, but not as the glory of thy mercy in the salvation of believers. How will this strike the adoring angels with holy admiration, and transport thy admiring saints with eternal rapture! The meanest believer shall enjoy more than the most enlarged heart can imagine while we are here; Christ will be admired in all those that believe, the meanest believer not excepted.When he shall come to be glorified in his saints,.... Or by them who are set apart for holiness and happiness by God the Father; whose sins are expiated by the blood and sacrifice of Christ; to whom he is made sanctification; and who are sanctified by the Spirit and grace of God; and in whom Christ has a peculiar interest, through his Father's gift, his own purchase, and the power of his grace: and when he comes a second time he will be glorified in these persons; he will appear glorious to them; he will come in his own glory both as God and man; and in his Father's glory, authority, and majesty, conferred on him as the Judge of the whole earth; and with the glory of his angels, who will accompany him. And he will also bestow a glory on them; their souls will be endowed with perfect knowledge and holiness; and their bodies will be made like to his glorious body; and both will shine like the sun in the kingdom of their Father; and this glory on the members of Christ will redound to the glory of him their head. And as he will then, in the most full and clear manner, display the glory of his person and perfections, of his wisdom, power, faithfulness, and goodness, set off the glory of his offices, and, the administration of them, and open the riches both of his grace and glory to them; so they will, in return, ascribe honour, praise, and glory, to him, and give him the glory of their salvation to all eternity:

and to be admired in all them that believe; who are the same with the saints; these are convertible terms; for no man can be a saint, unless he is a believer in Christ, let him make what pretensions to holiness he will: and no man can be a true believer in Christ, unless he is a saint; for true faith works by love, and in a way of holiness; and in those, or by those that are sanctified by faith in him, will he be admired when he appears a second time. He is admired by them now; he is with them the chiefest among ten thousands, and altogether lovely: they wonder at the glory and beauty of his person, and the fulness of his grace; and are amazed that such as they are should be admitted to communion with him; and how much more will they wonder, when they shall see him as he is? and he will be admired by others on the account of them, when they shall see those that they have despised, and persecuted, and accounted as the filth of the world, and the offscouring of all things, received into the arms of Jesus with all the expressions of tenderness and love; placed at his right hand, and set down with him on his throne, clothed with white robes, and crowns on their head, and palms in their hands: and he himself will be admired with them, when they shall see him whom they took to be a mere man, and who was a man of sorrows, and acquainted with griefs, and was loaded with reproach and ignominy, and at last suffered a shameful death, coming in the clouds of heaven in power and great glory as the Judge of quick and dead; thus will he be admired by them, in them, and with them.

(Because our testimony among you was believed) in that day; the phrase, "in that day", belongs to all that goes before, as that Christ shall take vengeance on wicked men, and they shall be punished by him, and he shall be glorified and admired in and by his people in that day, when he shall be revealed from heaven, and come to judge both quick and dead. Though some versions read it in construction with the clause immediately preceding, "because our testimony among you was believed in that day"; or concerning that day; that is, you gave credit to the testimony we bore, when among you, concerning this illustrious day of the Lord; or our testimony, the ministry of the word by us, in which we bore a testimony to the person and grace of Christ, to his first, and to his second coming, was received and embraced by you with a view to this day, and to the enjoyment of the glory of it. The Arabic version renders it, "for our testimony will be true in that day"; that is, it will appear to be so, everything we have said will be accomplished then. The Syriac version is very remote, "that our testimony concerning you may be believed in that day": but it is best to read this clause in a parenthesis, as in our version; which is an application of what is said to the Thessalonians, who might conclude, that since they had embraced the testimony of the Lord Jesus, borne unto him by his apostles, they would be found among the number of the saints and believers, in whom Christ would be glorified and admired; the consideration of which might animate and encourage them to endure afflictions and persecutions with patience, and to hold out to the end, and at last enjoy the heavenly glory, for which the apostle next prays.
