Revelation 21:22 But I saw no temple in it, for the Lord God Almighty and the Lamb are its temple.
23The city had no need of the sun or of the moon to shine in it, for the glory of God illuminated it. The Lamb is its light.
No physical temple in the new Jerusalem. The Lamb of God is the temple. The Father is the object of worship. In fact, the sun is no longer needed for light, God is light and will illuminate the city. There will be no darkness so the moon wont be needed either. I cant comprehend this glorious light eminating from the LORD. It will be amazing to say the least. Jesus is still referred to here as a lamb. Talk about humility! He is good with this and it speaks volumes unto how He relates & identifies with His people.
