in Revelation 21:2 New Jerusalem is “prepared as a bride adorned for her husband.” New Jerusalem as the bride of Christ is a corporate person, composed of all the believers.
This bride is adorned, not with physical jewels and fancy clothing, but with the virtues of Christ lived out through the believers. An example is 1 Timothy 2:9, “women adorn themselves in proper clothing with modesty and sobriety, not with braided hair and gold or pearls or costly clothing.” Our real modesty and sobriety come from Christ living in us.
Similarly Titus 2:10 speaks of “all good faithfulness” adorning “the teaching of our Savior God.” And 1 Peter 3:3-4 says that adorning should not be outward things but “the hidden man of the heart in the incorruptible adornment of a meek and quiet spirit, which is very costly in the sight of God.”
Peter also tells us that even gold and silver are corruptible in the eyes of God. Jesus Christ is longing for a bride adorned with incorruptible beauty which can only come from Himself.
Revelation 21:19 records “The foundations of the wall of the city [New Jerusalem] were adorned with every precious stone.” In 1 Peter 2:4-7 Christ Himself is the living Stone who is precious to God. The wall of the city (which is not physical because it is a living bride) is not adorned with physical jewels but with the precious Christ wrought into us through transformation.
The adorning of New Jerusalem as the bride is Christ Himself lived out through all His members. This is the highest beauty in the universe.
