Rev 21:1

21:1 a new heaven and a new earth. Some have thought that the new universe will be an entirely new world with no connection with the old. But Is. 65:17–25 and Rom. 8:21–23 indicate that a transfiguration of the old world is in view, like the way in which our new bodies will be transfigurations of the old (1 Cor. 15:35–57). Everything is new (v. 5), which indicates the thoroughness of transfiguration, but the result is redemption and not simply abolition of the old. See theological note “Heaven.”
