Answer
The Bible consistently warns us that this world will not last forever. “Heaven and earth will pass away,” Jesus said in Matthew 24:35. His statement was in the context of end times’ prophecies and the eternal nature of Jesus’ words: “My words will never pass away.” This means that trusting Jesus is wiser than trusting anything in this world.
Jesus also refers to the passing away of heaven and earth in Matthew 5:18. In Revelation 21:1, John writes of a new heaven and a new earth in the eternal state, having seen that “the first heaven and the first earth had passed away” cf: Isaiah 65:17 and 2 Peter 3:13. To “pass away” is to disappear or be no more. This refers to the physical heaven and earth—the material world and all it contains—but not to the spirits/souls of the inhabitants of those places. Scripture is clear that people will outlast the current material universe, some in a state of eternal bliss and some in a state of eternal misery, and that the current universe will be replaced by another that will never know the contamination of sin.
The method of this world’s destruction is revealed in 2 Peter 3:10–12: “The day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire. . . . That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat.” In Noah’s day, the world was destroyed with water, but God promised to send no more global floods «And I will establish my covenant with you; neither shall all flesh be cut off any more by the waters of a flood; neither shall there any more be a flood to destroy the earth. », (Genesis 9:11). In the Day of the Lord, the universe will be destroyed by fire.
The prophet Isaiah foretold the passing away of heaven and earth, too. “All the stars inThe sky will be dissolved, and the heavens rolled up like a scroll; all the starry host will fall like withered leaves from the vine, like shriveled figs from the fig tree” «And all the host of heaven shall be dissolved, and the heavens shall be rolled together as a scroll: and all their host shall fall down, as the leaf falleth off from the vine, and as a falling fig from the fig tree. », (Isaiah 34:4). The Lord assures His people that, even as the heaven and earth are passing away, His salvation is secure: “The heavens will vanish like smoke, the earth will wear out like a garment and its inhabitants die like flies. But my salvation will last forever, my righteousness will never fail” «Lift up your eyes to the heavens, and look upon the earth beneath: for the heavens shall vanish away like smoke, and the earth shall wax old like a garment, and they that dwell therein shall die in like manner: but my salvation shall be for ever, and my righteousness shall not be abolished. », (Isaiah 51:6).
Knowing that heaven and earth will pass away gives us perspective in life. This world is not our home. “We are looking forward to a new heaven and a new earth, where righteousness dwells” «Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness. », (2 Peter 3:13). Jesus tells us to have the proper priorities: “Do not store up for yourselves treasures on earth. . . . But store up for yourselves treasures in heaven” (Matthew 6:19-20). And Peter, after reminding us of the temporary nature of this world, says, “Dear friends, since you are looking forward to this, make every effort to be found spotless, blameless, and at peace.
with him” «Wherefore, beloved, since you anticipate these things, be diligent so that you may be discovered by him in peace, without blemish, and faultless. », (2 Peter 3:14).
