What does the Bible say about the heavenly Jerusalem?

The Bible describes the heavenly Jerusalem as the city of the living God, where true believers, those whose names are written in heaven, dwell in perfect peace. This is contrasted with the earthly Jerusalem, which has been a type or shadow of the spiritual reality that is fulfilled in Christ and His church. Hebrews 12:22 highlights this distinction, proclaiming that believers have come to Mount Zion and the heavenly Jerusalem, emphasizing that it is the gathering of God's elect from every nation that truly constitutes His holy city. This heavenly city embodies the peace between God and sinners made possible through the blood of Jesus Christ, which is central to the new covenant established in His death and resurrection.
