The bride of Jesus
The bride of the Son of God or The Messiah is the new city that comes down from heaven and all that live in her make up the bride.
This heavenly city is some times called the New Jerusalem.
In Revelation 21:6-8 speaks about who will be in this new Heaven and those who will not make it.
The bride is made up of all the people that has taken the free gift of the water of life.
The Bride of Christ
1 Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea. 2 I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. 3 And I heard a loud voice from the throne saying, "Now the dwelling of God is with men, and he will live with them. They will be his people, and God himself will be with them and be their God. 4 He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away."
5 He who was seated on the throne said, "I am making everything new!" Then he said, "Write this down, for these words are trustworthy and true."
6 He said to me: "It is done. I am the Alpha and the Omega, the Beginning and the End. To him who is thirsty I will give to drink without cost from the spring of the water of life. 7 He who overcomes will inherit all this, and I will be his God and he will be my son. 8 But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars–their place will be in the fiery lake of burning sulfur. This is the second death."
9 One of the seven angels who had the seven bowls full of the seven last plagues came and said to me, "Come, I will show you the bride, the wife of the Lamb." 10 And he carried me away in the Spirit to a mountain great and high, and showed me the Holy City, Jerusalem, coming down out of heaven from God.
17 The Spirit and the bride say, "Come!" And
let him who hears say, "Come!" Whoever is thirsty, let him come; and
whoever wishes, let him take the free gift of the water of life.
