"Being built upon the foundation of the apostles and prophets, Christ Jesus Himself being the cornerstone; In whom all the building, being fitted together, is growing into a holy temple in the Lord; In whom you also are being built together into a dwelling place of God in spirit." (Ephesians 2:20-22)
God likens His chosen people to a spouse for His satisfaction in love.
In Revelation 2 and 3 the Spirit speaks to the churches, but in Rev. 22:17 the Spirit and the bride speak together. The churches will consummate the New Jerusalem, the bride of Christ as His counterpart.
Rev. 21:2 - And I saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband.
... The final sign, which is also the greatest, is the New Jerusalem, signifying the composition of the totality of God’s redeemed saints throughout the generations, who have been regenerated, transformed, and glorified. It is not a material, lifeless city but a corporate living person as the bride, having Christ, such a wonderful person, as her husband. Footnotes 2, Rev. 21:2
