Light of God, Book of Revelation
And he carried me in spirit onto a great and high mountain, and showed me the great city, holy Jerusalem, coming down out of Heaven from God, having the glory of God. And its light was like a very precious stone, as a jasper stone, being clear as crystal, (Rev 21:10-11)
And the city had no need of the sun, nor of the moon, that they might shine in it, for the glory of God illuminated it, even its lamp is the Lamb. And the nations of the ones saved will walk in its light; and the kings of the earth bring their glory and honor into it. And its gates may not at all be shut by day, for no night will be there. (Rev 21:23-25)
And night will not be there; and they have no need of a lamp or a light of the sun, because the Lord God will illumine them. And they shall reign to the ages of the ages. (Rev 22:5)
