(Revelation 5:1-10) 5
And I saw in the right hand of the One seated upon the throne a scroll written within and on the reverse side, sealed tight with seven seals. 2 And I saw a strong angel proclaiming with a loud voice: “Who is worthy to open the scroll and loose its seals?” 3 But neither in heaven nor upon earth nor underneath the earth was there a single one able to open the scroll or to look into it. 4 And I gave way to a great deal of weeping because no one was found worthy to open the scroll or to look into it. 5 But one of the elders says to me: “Stop weeping. Look! The Lion that is of the tribe of Judah, the root of David, has conquered so as to open the scroll and its seven seals.” 6 And I saw standing in the midst of the throne and of the four living creatures and in the midst of the elders a lamb as though it had been slaughtered, having seven horns and seven eyes, which [eyes] mean the seven spirits of God that have been sent forth into the whole earth. 7 And he went and at once took [it] out of the right hand of the One seated on the throne. 8 And when he took the scroll, the four living creatures and the twenty-four elders fell down before the Lamb, having each one a harp and golden bowls that were full of incense, and the [incense] means the prayers of the holy ones. 9 And they sing a new song, saying: “You are worthy to take the scroll and open its seals, because you were slaughtered and with your blood you bought persons for God out of every tribe and tongue and people and nation, 10 and you made them to be a kingdom and priests to our God, and they are to rule as kings over the earth.”
REFERENCE SCRIPTURES IN THE NWT
(Revelation 1:4-6)
4 John to the seven congregations that are in the [district of] Asia: May YOU have undeserved kindness and peace from “The One who is and who was and who is coming,” and from the seven spirits that are before his throne, 5 and from Jesus Christ, “the Faithful Witness,” “The firstborn from the dead,” and “The Ruler of the kings of the earth.” To him that loves us and that loosed us from our sins by means of his own blood— 6 and he made us to be a kingdom, priests to his God and Father—yes, to him be the glory and the might forever. Amen.
(1 Peter 2:8, 9)
. . .. 9 But YOU are “a chosen race, a royal priesthood, a holy nation, a people for special possession, that YOU should declare abroad the excellencies” of the one that called YOU out of darkness into his wonderful light.
(Matthew 19:27, 28)
27 Then Peter said to him in reply: “Look! We have left all things and followed you; what actually will there be for us?” 28 Jesus said to them: “Truly I say to YOU, In the re-creation, when the Son of man sits down upon his glorious throne, YOU who have followed me will also yourselves sit upon twelve thrones, judging the twelve tribes of Israel.
(Revelation 20:4)
4 And I saw thrones, and there were those who sat down on them, and power of judging was given them. Yes, I saw the souls of those executed with the ax for the witness they bore to Jesus and for speaking about God, and those who had worshiped neither the wild beast nor its image and who had not received the mark upon their forehead and upon their hand. And they came to life and ruled as kings with the Christ for a thousand years.
(Revelation 22:3-5)
3 And no more will there be any curse. But the throne of God and of the Lamb will be in [the city], and his slaves will render him sacred service; 4 and they will see his face, and his name will be on their foreheads. 5 Also, night will be no more, and they have no need of lamplight nor [do they have] sunlight, because Jehovah God will shed light upon them, and they will rule as kings forever and ever.
