3:7 {6} But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
(6) Thirdly, he pronounces that it will not be harder for God to burn heaven and earth with fire, in that day which is appointed for the destruction of the wicked (which he will also do) than it was for him in times past to create them only with his word, and afterward to overwhelm them with water.
3:7 By the same word. The heavens and earth of old were formed by the word of God, but the same word, which has always been sure, declares that they are reserved for fire. See Ps 50:3 97:03:00 Isa 66:15,24 Da 7:9 Mal 4:1.
Against the day of judgment and perdition of ungodly men. This destruction by fire will be when the Lord is revealed in judgment and when perdition comes on ungodly men.
3:7 But the heavens and the earth, that are now - Since the flood. Are reserved unto fire at the day wherein God will judge the world, and punish the ungodly with everlasting destruction.
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.
