New Jerusalem will be heavenly. All we have to do is examine its description as given in Revelation 21:9 through 22:3, and we shall see that, because of its dimensions and features, it would never fit in with the terrain of old Jerusalem. In the inspired description, the New Jerusalem is called “the bride, the Lamb’s wife.”

7. In what way is the holy city, New Jerusalem, “the Lamb’s wife”?

⁷ In what way is the holy city “the bride, the Lamb’s wife”? In that it is made up of the congregation of Christ’s anointed disciples, his joint heirs in the Messianic kingdom. (Ephesians 5:25-27; 2 Corinthians 11:2; Revelation 19:7, 8; 22:17) With reference to each of these the glorified Jesus said: “I will write upon him the name of my God and the name of the city of my God, the new Jerusalem which descends out of heaven from my God, and that new name of mine.” (Revelation 3:12) Members of the “bride” are spiritual Israelites, in the new covenant, and they number 144,000. Jesus Christ builds them upon himself as the “rock-mass,” and his twelve apostles rest like complementary foundation stones upon him.​—Matthew 16:18; Revelation 7:4-8; 14:1-5; 21:14.
