Revelation 21:22-23

22When I looked, I saw that there was no temple in the city. The Lord God, who has all power and authority, is there himself. The Lamb is also there. So people do not need a special place to worship him there.

23Also, the city does not need the sun or the moon to shine on it. God's bright glory gives light to the city. The Lamb is the lamp that gives it light.
