Now that the old, sinful is over, God can start again and a new Heaven and a new Earth will follow.
Moreover, a new Jerusalem will come down from Heaven to Earth, says the Bible ( Revelation 21:2). Light from the sun or moon no longer needs it says the Bible, for the Light of the glory of God will illuminate the Earth and Christ is its lamp (Revelation 21:23). Night will be no more. In the middle of the new city a river will spring from the throne of God and of the Lamb Jesus. And on both sides of the river are Trees of Life that bear fruit every month and bring healing. Only those listed in the Book of the Living will live in the city.
Revelation 21:2 "And I saw the holy city — the new Jerusalem — descending out of heaven from God, made ready like a bride adorned for her husband."
Revelation 21:23 "The city does not need the sun or the moon to shine on it, because the glory of God lights it up, and its lamp is the Lamb".
