Charles Ellicott Commentary Revelation 1:6

"and he made us [to be] a kingdom, [to be] priests unto his God and Father; to him [be] the glory and the dominion for ever and ever. Amen." — Revelation 1:6 (ASV)

And has made us kings and priests to God and his Father; to him be glory and dominion forever (or, to the ages).—The symbol of washing in the last verse naturally leads on to the thought of consecration, accompanied by blood-sprinkling, to the work of the priest (Exodus 19:6; Exodus 19:10; Exodus 24:8; Hebrews 9:21). The book will declare the kingship and priesthood of the children of God—a sovereignty over human fears and sufferings—their priesthood in their lives of consecration, and their offering of themselves even to death.

“And all your saints do overcome
By Your blood and their martyrdom.”

The doxology here is twofold: glory and dominion. The doxologies in which the Redeemed Church takes part grow in strength in the earlier chapters of this book. It is threefold in Revelation 4:9-11; fourfold in Revelation 5:13; and it reaches the climax of sevenfold in Revelation 7:12.
