3:5-10 Had these scoffers considered the dreadful vengeance with which God swept away a whole world of ungodly men at once, surely they would not have scoffed at his threatening an equally terrible judgment. The heavens and the earth which now are, by the same word, it is declared, will be destroyed by fire. This is as sure to come, as the truth and the power of God can make it. Christians are here taught and established in the truth of the coming of the Lord. Though, in the account of men, there is a vast difference between one day and a thousand years, yet, in the account of God, there is no difference. All things past, present, and future, are ever before him: the delay of a thousand years cannot be so much to him, as putting off any thing for a day or for an hour is to us. If men have no knowledge or belief of the eternal God, they will be very apt to think him such as themselves. How hard is it to form any thoughts of eternity! What men count slackness, is long-suffering, and that to us-ward; it is giving more time to hisown people, to advance in knowledge and holiness, and in the exercise of faith and patience, to abound in good works, doing and suffering what they are called to, that they may bring glory to God. Settle therefore in your hearts that you shall certainly be called to give an account of all things done in the body, whether good or evil. And let a humble and diligent walking before God, and a frequent judging of yourselves, show a firm belief of the future judgment, though many live as if they were never to give any account at all. This day will come, when men are secure, and have no expectation of the day of the Lord. The stately palaces, and all the desirable things wherein wordly-minded men seek and place their happiness, shall be burned up; all sorts of creatures God has made, and all the works of men, must pass through the fire, which shall be a consuming fire to all that sin has brought into the world, though a refining fire to the works of God's hand. What will become of us, if we set our affections on this earth, and make it our portion, seeing all these things shall be burned up? Therefore make sure of happiness beyond this visible world.
10. The certainty, suddenness, and concomitant effects, of the coming of the day of the Lord. Faber argues from this that the millennium, &c., must precede Christ's literal coming, not follow it. But "the day of the Lord" comprehends the whole series of events, beginning with the pre-millennial advent, and ending with the destruction of the wicked, and final conflagration, and general judgment (which last intervenes between the conflagration and the renovation of the earth).
will—emphatical. But (in spite of the mockers, and notwithstanding the delay) come and be present the day of the Lord SHALL.
as a thief—Peter remembers and repeats his Lord's image (Lu 12:39, 41) used in the conversation in which he took a part; so also Paul (1Th 5:2) and John (Re 3:3; 16:15).
the heavens—which the scoffers say' shall "continue" as they are (2Pe 3:4; Mt 24:35; Re 21:1).
with a great noise—with a rushing noise, like that of a whizzing arrow, or the crash of a devouring flame.
elements—the component materials of the world [Wahl]. However, as "the works" in the earth are mentioned separately from "the earth," so it is likely by "elements," mentioned after "the heavens," are meant "the works therein," namely, the sun, moon, and stars (as Theophilus of Antioch [p. 22, 148, 228]; and Justin Martyr [Apology, 2.44], use the word "elements"): these, as at creation, so in the destruction of the world, are mentioned [Bengel]. But as "elements" is not so used in Scripture Greek, perhaps it refers to the component materials of "the heavens," including the heavenly bodies; it clearly belongs to the former clause, "the heavens," not to the following, "the earth," &c.
melt—be dissolved, as in 2Pe 3:11.
the works … therein—of nature and of art.
