2 Peter 3:5

For this they are wilfully ignorant of. The ignorance of these unbelievers is wilful and inexcusable, when they question the existence of a Supreme Being, of a future state, wherein God will reward the good and punish the wicked; when they laugh at all the miracles, and all the extraordinary effects of God’s power and justice, such as was the general flood or deluge, by which God destroyed the wicked by an inundation of waters. And as our blessed Saviour said of those, who would not believe in the days of Noe[Noah], “They were eating and drinking, marrying, and giving in marriage,…and they knew not till the flood came, and took them all away: so shall also the coming of the Son of man be.” (Mattew xxiv. 38. 39.) (Witham)

1. We begin with the apostle's account of the destruction which has once already come upon the world ( v. 5, 6): By the word of God the heavens were of old, and the earth standing out of the water and in the water, whereby the world that then was, being overflowed with water, perished. Originally the world was otherwise situated, the waters were most wisely divided at the creation and most beneficially for us; some of the waters had proper repositories above the firmament, here called the heavens (as it is also Gen 1 8), and others, under the firmament, gathered together unto one place; there were then both sea and dry land, commodious habitation for the children of men. But now, at the time of the universal deluge, the case is strangely altered; the waters which God had divided before, assigning to each part its convenient receptacle, now does he, in anger, throw together again in a heap. He breaks up the fountain of the great deep, and throws open the windows (that is, the clouds) of heaven (Gen 7 11), till the whole earth is overflowed with water, and not a spot can be found upon the highest mountains but what is fifteen cubits under water, Gen 7 20. Thus he made known at once his terrible power and his fierce anger, and made an end of a whole world at once: The world that then was, being overflowed with water, perished, v. 6. Is not here a change and a most awful change! And then it is to be observed that all this was done by the word of God; it was by his powerful word that the world was made at first, and made in so commodious and beautiful a frame and order, Heb 11 3, Katertisthai. He said, Let there be a firmament, etc., Gen 1 6, 7. And let the waters under the heaven be gathered together unto one place, etc., v. 9, 10. Thus he spoke, and it was done, Ps 33 9. Thus, says our apostle, by the word of the Lord the heavens were, as they were of old (that is, at first creation) and the earth (as it was at first a terraqueous globe) standing out of the water and in the water. Not is it only the first frame and order of the world that is here said to be by the word of God, but the after-confusion and ruin of the world, as well as the utter destruction of its inhabitants, were also by the same word; none but that God who stretched out the heavens and laid the foundation of the earth could destroy and overthrow such a vast fabric at once. This was done by the word of his power, and it was also done according to the word of his promise; God had said that he would destroy man, even all flesh, and that he would do it by bringing a flood of waters upon the earth, Gen 6 7, 13, 17. This was the change which God had before brought upon the world, and which these scoffers had overlooked; and now we are to consider,

Verses 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;…
