Revelation 7:9-10, 13-15

After these things I looked, and this is what I saw: a vast multitude which no one could count, [gathered] from every nation and from all the tribes and peoples and languages [of the earth], standing before the throne and before the Lamb (Christ), dressed in white robes, with palm branches in their hands; and in a loud voice they cried out, saying, “ S alvation [belongs] to our God who is seated on the throne, and to the Lamb [our salvation is the Trinity’s to give, and to God the Trinity we owe our deliverance].”

Then one of the elders responded, saying to me, “These who are dressed in the long white robes—who are they, and from where did they come?” I said to him, “My lord, you know [the answer].” And he said to me, “These are the people who come out of the great tribulation (persecution), and they have washed their robes and made them white in the blood of the Lamb [because of His atoning sacrifice]. [Gen 49:11; Dan 12:1] For this reason, they are [standing] before the throne of God; and they serve Him [in worship] day and night in His temple; and He who sits on the throne will spread His tabernacle over them and shelter and protect them [with His presence]. [Rev 21:3]
