Rev 5..made them a kingdom of priests to serve our God, they shall rule on earth

• rev 5
  I saw a scroll in the right hand of the one who sits on the throne; it was covered with writing on both sides and was sealed with seven seals. 2 And I saw a mighty angel, who announced in a loud voice, “Who is worthy to break the seals and open the scroll?” 3 But there was no one in heaven or on earth or in the world below[a] who could open the scroll and look inside it. 4 I cried bitterly because no one could be found who was worthy to open the scroll or look inside it. 5 Then one of the elders said to me, “Don't cry. Look! The Lion from Judah's tribe, the great descendant of David, has won the victory, and he can break the seven seals and open the scroll.”
  
  

  
  

  •  6 Then I saw a Lamb standing in the center of the throne, surrounded by the four living creatures and the elders. The Lamb appeared to have been killed (i seen that)
• 
  
•  It had seven horns and seven eyes, which are the seven spirits of God that have been sent through the whole earth. 7 The Lamb went and took the scroll from the right hand of the one who sits on the throne. 8 As he did so, the four living creatures and the twenty-four elders fell down before the Lamb. Each had a harp and gold bowls filled with incense, which are the prayers of God's people. 9 They sang a new song:
•  “You are worthy to take the scroll
  and to break open its seals.
  For you were killed, and by your sacrificial death you bought for God
  people from every tribe, language, nation, and race.
  10 You have made them a kingdom of priests to serve our God, and they shall rule on earth.”
