The Glory of New Jerusalem

"I did not see a temple in the city, because the Lord God Almighty and the Lamb are its temple. The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp. The nations will walk by its light, and the kings of the earth will bring their splendor into it. On no day will its gates ever be shut, for there will be no night there. The glory and honor of the nations will be brought into it. Nothing impure will ever enter it, nor will anyone who does what is shameful or deceitful, but only those whose names are written in the Lamb's book of life." (Revelation 21:22-27 - New International Version)

The New Jerusalem has no temple. The temple in the Old Testament represented God's presence with His people. There will be no temple in the New Jerusalem because Jesus will be there.

The city will not require the light of the sun or moon. The glory of God will illuminate it. Notice that John does not say that there will be no sun or moon or stars, only that the New Jerusalem will not require their light.

All the saved will walk in the light of God's glory in this city. The gates of the city will never be shut. No sin or sinner will be allowed to enter the city. The redeemed whose names are in the Lamb's book of life will be there.
