What is the significance of the New Jerusalem in Christian theology?

In Revelation 21, the New Jerusalem is depicted as the bride of Christ, symbolizing the ultimate union between God and His people. This city is coming down from God, adorned and prepared for those He has chosen, representing the culmination of salvation and restoration. It embodies the community of believers who have been redeemed through Christ's sacrifice and reflects God's eternal glory. Understanding the New Jerusalem's significance helps Christians to recognize their identity as members of a divine kingdom, where they are called to participate in worship and fellowship, both now and eternally.
