After this I looked and saw a multitude too large to count, from every nation and tribe and people and tongue, standing before the throne and before the Lamb. They were wearing white robes and holding palm branches in their hands. And they cried out in a loud voice: "Salvation to our God, who sits on the throne, and to the Lamb!"
He says: “It is not enough for You to be My Servant, to raise up the tribes of Jacob, and to restore the protected ones of Israel. I will also make You a light for the nations, to bring My salvation to the ends of the earth.”
Significance
In the Second Servant Song, the LORD widens the Servant's vocation past the gathering of Israel: "It is not enough for You to be My Servant, to raise up the tribes of Jacob… I will also make You a light for the nations, to bring My salvation to the ends of the earth" (Isa 49:6). In its original setting this is a commission — a promised scope of salvation not yet realized within the Old Covenant, whose own afterlife in the OT is thin (the ATN notes the Song "waits for canonical activation in the Christ-event"). Revelation 7:9-10 shows that promise arrived at its consummation: "a multitude too large to count, from every nation and tribe and people and tongue, standing before the throne and before the Lamb," who "cried out in a loud voice: 'Salvation to our God… and to the Lamb!'" The Servant's salvation has in fact reached "the ends of the earth," and the nations are gathered as worshippers. This is Promise-Fulfillment along a Redemptive-Historical arc, not a type of the person: there is no person-or-institution functioning as type whose pattern escalates into an antitype; rather a prophetic commission of universal salvation finds its eschatological realization (the trajectory the ATN traces from Isa 49:6 through Luke 2:32, Luke 24:47, and Acts 13:46-47 to its terminus here). The link is conceptual, not verbal — John's fourfold "nation and tribe and people and tongue" is his own idiom, not Isaiah's wording — hence an Echo of the to-the-ends-of-the-earth scope rather than a citation. (This is the distinct Isa 49:6 salvation-reaching-the-nations strand; the Abrahamic all-the-families-blessed strand of the same multitude is paired separately in Rev 7:9 → Gen 12:3.) The telos: the Servant's "light to the nations" is not finally a missiological statistic but the Lamb Himself become the satisfied gladness of every tribe — the salvation He brought to the ends of the earth is enjoyed face-to-face before the throne, so that the worshipping multitude's cry is the sight of Christ become the savoring of Christ, the very thing for which the nations were sought.
