The Holy City Jerusalem - Revelation 21-9-12

Revelation - 21:9-12 ESV 

Then came one of the seven angels who had the seven bowls full of the seven last plagues and spoke to me, saying, “Come, I will show you the Bride, the wife of the Lamb.” And he carried me away in the Spirit to a great, high mountain, and showed me the holy city Jerusalem coming down out of heaven from God, having the glory of God, its radiance like a most rare jewel, like a jasper, clear as crystal. 

The Bride of Christ is the New Jerusalem, which is the resurrection of the Garden of Eden. She has the radiance and purity of Christ, for she is the body of Christ.
