Here is their twist on it...
From the Rev Climax book:
“I saw also the holy city, New Jerusalem, coming down out of heaven from God and prepared as a bride adorned for her husband.” (Revelation 21:2)
New Jerusalem is the bride of Christ, made up of the anointed Christians who remain faithful to death and who are raised to become kings and priests with the glorified Jesus. (Revelation 3:12; 20:6) Just as earthly Jerusalem became the seat of government in ancient Israel, the magnificent New Jerusalem and her Bridegroom make up the government of the new system of things. This is the new heaven. The ‘bride comes down out of heaven,’ not literally, but in the sense of directing attention to the earth. The Lamb’s bride is to be his loyal helpmeet in operating a righteous government over all mankind. A blessing indeed for the new earth!
4 John tells us further: “With that I heard a loud voice from the throne say: ‘Look! The tent of God is with mankind, and he will reside with them, and they will be his peoples. And God himself will be with them.’” (Revelation 21:3) When Jehovah made the Law covenant with the then new nation of Israel, he promised: “I shall certainly put my tabernacle in the midst of you, and my soul will not abhor you. And I shall indeed walk in the midst of you and prove myself your God, and you, on your part, will prove yourselves my people.” (Leviticus 26:11, 12) Now Jehovah is making a similar promise to faithful humans. During the thousand-year Judgment Day, they will become a very special people to him.
5 During the Millennial Reign, Jehovah will “reside” among mankind in a temporary arrangement, he being represented by his royal Son, Jesus Christ. At the end of the Thousand Year Reign, however, when Jesus hands the Kingdom over to his Father, no royal representative or intercessor will be needed. Jehovah will reside spiritually with “his peoples” in a permanent and direct way. (Compare John 4:23, 24.) What a lofty privilege for restored humanity!
