Context: Revelation 21:2 stands at the hinge of the book's closing vision. Revelation 20 has concluded with the final judgment and the second death (20:11-15). Revelation 21:1 inaugurates the new-creation vision: "Then I saw a new heaven and a new earth, for the first heaven and earth had passed away, and the sea was no more." Verse 2 then delivers the central Christological image of the consummation: "I saw the holy city, the new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband." The verse fuses three distinct OT/NT streams into a single eschatological reality: (1) the holy city motif from Isaiah 52:1 ("put on your beautiful garments, O Jerusalem, the holy city"), (2) the new Jerusalem motif from Isaiah 65-66 and Ezekiel's visionary city (Ezek 40-48), and (3) the bride adorned motif from Isaiah 61:10 ("as a bride adorns herself with her jewels") transposed onto the city itself. The city is the bride; the bride is the city. This identification — developed at Rev 21:9-10, where the angel says "I will show you the bride, the wife of the Lamb" and then "showed me the holy city Jerusalem coming down out of heaven from God" — is not incidental metaphor-swapping but a deliberate fusion of the two-women (Hagar/Sarah, present-Jerusalem/Jerusalem-above) and two-cities (Babylon/New Jerusalem) and marriage (Christ and His church) trajectories that run through the canon.

Christological Connection: Revelation 21:2's theological meaning is that the long redemptive-historical arc of city, bride, and new-covenant mother reaches its consummated form in a single descent. The city-bride — holy, new, prepared, adorned — comes down from God. Three structural features bear christological weight: (1) the city has a divine origin ("out of heaven from God"); (2) the city has been prepared and adorned by divine action (both perfect passive participles — ἡτοιμασμένην, κεκοσμημένην — marking completed divine work); (3) the city is for the Lamb as bride is for husband. The trajectory that began with Sarah as the first matriarch through whom covenant children came by divine promise (not by flesh) finds its cosmic resolution here: the heavenly mother's children, so many that they were typologically the "many more" of Isaiah 54:1, are now gathered into the city their mother was always going to be.
The consummation of the Sarah trajectory at Rev 21:2 operates on three lines Paul opens at Galatians 4:21-31. First, Sarah ↔ heavenly Jerusalem ↔ our mother (Gal 4:26) finds its telos in the visible descent of the new Jerusalem as the bride. The heavenly mother that was already our mother in the already (Gal 4:26; Heb 12:22) now descends into the new creation. Second, the Hagar/Sarah contrast (two women, two covenants, two Jerusalems — Gal 4:24-25) is now decisively resolved: the present Jerusalem "in slavery with her children" has passed away with the first heaven and first earth (Rev 21:1), and only the Jerusalem-above stands. The earlier allegorical contrast Paul drew from the two historical matriarchs is cashed out in visible cosmic geography. Third, the bride adorned imagery — κεκοσμημένην, "having been adorned" — connects the city-bride of Revelation to the ecclesial bride of Ephesians 5:25-27 (whom Christ "might present to Himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish"). The adornment is not the bride's own achievement; it is Christ's sanctifying work applied to her. In the Sarah-trajectory framing, this means the matriarchal-mother line that always produced children by divine power rather than by flesh is gathered into a bride whose very holiness is the Lamb's accomplishment.
The contrast with Babylon (Rev 17-18), the "great prostitute," is deliberate and runs on the same two-women ground that Gal 4 exploits. Babylon is the consummation of the Hagar-line: fleshly, adulterous, enslaving, bearing children for bondage. The new Jerusalem is the consummation of the Sarah-line: free, faithful, Spirit-born, bearing children for glory. Revelation's closing vision is Paul's Gal 4 argument at cosmic scale and eschatological finality.
The already/not-yet staging completes. Already (Heb 12:22): believers have come to Mount Zion and the heavenly Jerusalem through Christ's mediation and sprinkled blood. Not yet (Rev 21:2): the heavenly city descends into the new creation, and the bride is revealed to the universe in her adorned completeness. The same Christ who mediated the already-arrival is the husband for whom the bride is prepared in the not-yet. The same divine power that opened Sarah's dead womb (Rom 4:19-21), emptied Christ's sealed tomb (Rom 4:24-25), made believers alive when dead in trespasses (Eph 2:5), and admitted them to the heavenly Jerusalem in the already (Heb 12:22) — that same power finally descends the city-bride into the new creation and completes the trajectory that began with one barren woman laughing in a tent at Mamre. "Is anything too hard for the LORD?" (Gen 18:14). Revelation 21 is the final answer.
Connection Method(s): Promise-Fulfillment (primary) — the text explicitly consummates a cluster of OT verbal promises: Isaiah's holy-city (52:1), bride-adornment (61:10), new-heavens-and-earth (65:17), and barren-mother-made-fruitful (54:1); Ezekiel's visionary city (40-48); Jeremiah's new covenant (31:31-34). Revelation 21:2 is prophetic promise cashed out at cosmic scale. Also Redemptive-Historical Progression — the verse is the terminal node of the canonical arc, receiving threads from Eden, Abraham-Sarah, Sinai, Zion, exile-restoration, Christ's cross-and-resurrection, and the church age. Also Longitudinal Theme — Revelation 21:2 is a convergence point for multiple longitudinal themes: Marriage and Bride (the Lamb's wife), Temple and Presence (the city as consummate holy-place), New Creation, Land and Inheritance, and the heavenly-mother motif that flows from Sarah through Isaiah to Paul. Also Contrast — the Babylon/New Jerusalem opposition across Rev 17-22 is structurally essential to the book's argument and to the Sarah-Hagar / present-Jerusalem / Jerusalem-above dialectic Paul articulates at Gal 4:21-31. Typology is not claimed as the primary lens (anti-default check): Sarah and the new Jerusalem are not in a type-antitype relation of escalated structural correspondence. Rather, the "one mother / many children born by divine promise" pattern is equated in kind with the city-bride whose children are adorned and gathered — analogical continuity, not type escalation. This matches TT 139's consistent classification of the Sarah trajectory as Promise-Fulfillment + Analogy + Longitudinal Theme + Contrast, without claiming Typology.
