The Apostle John writes that he saw “a new heaven and a new earth: for the first heaven and the first earth were passed away…” (v.1). The implication is that the heavens are remade by God or, at least, the surface of the earth is refurbished, because is it is described as “new.“
2 Peter 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
As I wrote in our Revelation 19 study, I believe some of this is symbolic language. Of course some is literal but we need to understand which. Read Do the heavens literally pass away or don’t they? The word ‘earth’ in 2 Peter 3:10 means the earthlings. The people are judged according to their works. The ‘elements’ are the ‘fundamental principles’ by which the world has been governed by man. The Greek word translated ‘elements’ is στοιχεῖον (stoicheion), which is related to ‘something orderly in arrangement.’ But all order and government is changed at Christ’s return, which is followed by the new heaven and new earth. The old heavens, both spiritual heavens and the physical environment of the earth are changed. They are restored to the state of creation before Adam’s sin.
The earth is to undergo a purification and a renewal to make it fit for the home of the saints in glory. The old state of things shall be succeeded by a new order, both physical and moral. (This also strengthens the argument that the resurrected saints are not again to be found physically on earth until the earth is purified and prepared for them, which is after the millennium.)
