2 Thessalonians 1:8

In flaming fire
Which may either refer to Christ, who will be revealed from heaven in such a manner; and whose coming will be as the lightning, not only sudden, but glorious, illustrious, and visible; he will be seen and easily discerned; there will be such a light and flaming fire about him, which, as it will serve to make him visible, will greatly add to the majesty of his appearance, and strike terror to his enemies, and burn them up round about; see ( Daniel 7:7 Daniel 7:9 Daniel 7:10 ) ( Psalms 97:3 Psalms 97:4 ) or else it may refer to the angels, who shall descend in fiery forms, which is agreeably to their nature, ( Psalms 104:4 ) and so they appeared in the forms of horses of fire, and chariots of fire, when Elijah was carried up to heaven. And it is a tradition of the Jews ^F26, that the angel Gabriel descended (avad abwhlvb) , "in a flame of fire", to burn Moses, as he was in the inn, when upon his journey from Midian to Egypt: or this clause may be read in construction with the following, as it is in the Vulgate Latin and Syriac versions, "in flaming fire taking vengeance"; and so expresses the manner in which vengeance will be taken on the wicked by Christ, the Judge of all, to whom it belongs: and the punishment of ungodly men is often signified by fire, and flames of fire, by the fire of hell, and a lake which burns with fire and brimstone, by a furnace of fire, everlasting fire, and fire that cannot be quenched, to set forth the endless torture and inconceivable misery of the damned; and it may be, some regard is had to the general conflagration, which will be at the coming of Christ, when the heavens, being on fire, shall be dissolved, the elements shall melt with fervent heat, and the earth, and all that is in it, shall be burnt up, when the bodies of the wicked, then living, will be consumed in flames of fire, and their souls feel the wrath of the Almighty. The persons who will then be punished, and on whom vengeance will be taken, are described as follows,

on them that know not God;
which is a periphrasis, or common character of the Gentiles, ( 1 Thessalonians 4:5 ) who know not the one, true, and living God; or know him not so as to glorify him as God, and be thankful to him for the mercies they receive from him, and still less know him in Christ Jesus; which ignorance of theirs is not without sin, nor will it excuse from punishment; for though vengeance will not be taken on them, because they have not a spiritual saving knowledge of God, in the Mediator Jesus Christ, who never was revealed to them; yet forasmuch as they had the light and law of nature, by which the being of God, and the invisible perfections of his nature might be seen and understood, and much of his will, with respect to moral good and evil, be known, against both which they have rebelled, and having sinned, will perish without law: though it may also include all such persons, who having been favoured with an external revelation, have professed to know God, and yet in works have denied him:

and that obey not the Gospel of the Lord Jesus Christ;
of which Christ is the author, was the preacher, and is the sum and substance; which is good news and glad tidings of the grace of, God, of peace, pardon, righteousness, life, and salvation by Christ; which may be said to be obeyed, when it is received and embraced by faith, with and from the heart, and confession is made of it with the mouth, and the ordinances of it are submitted to; and which is called the obedience of faith, because faith without obedience is not right, and obedience without faith is of no avail: but all that hear the Gospel do not obey it; there are some that disbelieve and reject the doctrines and ordinances of it, and others that, do profess it, and do not yield a cordial and cheerful obedience to it; both may be reckoned among the disobeyers of it: and though the unbelieving Jews may be chiefly designed here, yet deists of every age and place, where the Gospel revelation has come, and carnal professors, and profane despisers everywhere, may be included; whose condemnation will be aggravated by the external light which has shone around them, and they have hated; the severest punishment will be inflicted on them; it will be more tolerable for Tyre and Sidon, Sodom and Gomorrah, than for such persons; see ( 1 Peter 4:17 ) .
