John Wesley on Revelation 21:1

And I saw - So it runs, Rev 19:11, 20:1,4,11, in a succession. All these several representations follow one another in order: so the vision reaches into eternity. A new heaven and a new earth - After the resurrection and general judgment. St. John is not now describing a flourishing state of the church, but a new and eternal state of all things. For the first heaven and the first earth - Not only the lowest part of heaven, not only the solar system, but the whole ethereal heaven, with all its host, whether of planets or fixed stars, Isai 34:4 Matt 24:29. All the former things will be done away, that all may become new, verses 4,5, 2Peter 3:10,12. Are passed away - But in the fourth verse it is said, "are gone away." There the stronger word is used; for death, mourning, and sorrow go away all together: the former heaven and earth only pass away, giving place to the new heaven and the new earth.
