We will be kings and priests of God the Father

Revelation 5:7-10 ASV
(7)  And he came, and he taketh it out of the right hand of him that sat on the throne.
(8)  And when he had taken the book, the four living creatures and the four and twenty elders fell down before the Lamb, having each one a harp, and golden bowls full of incense, which are the prayers of the saints.
(9)  And they sing a new song, saying, Worthy art thou to take the book, and to open the seals thereof: for thou wast slain, and didst purchase unto God with thy blood men of every tribe, and tongue, and people, and nation,
(10)  and madest them to be unto our God a kingdom and priests; and they reign upon the earth.

Revelation 20:6 ASV
Blessed and holy is he that hath part in the first resurrection: over these the second death hath no power; but they shall be priests of God and of Christ, and shall reign with him a thousand years.

Revelation 22:5 ASV
And there shall be night no more; and they need no light of lamp, neither light of sun; for the Lord God shall give them light: and they shall reign for ever and ever.
