“Unto Him that loved us and washed us from our sins in His own blood and has made us kings and priests unto God and His Father; to Him be glory and dominion forever and ever. Amen. Behold, He comes with clouds; and every eye shall see Him, and they also which pierced Him: and all kindreds of the earth shall wail because of Him. Even so, Amen.”- Revelation 1:5-7.

It is a wonderful doxology which John has given us— “Unto Him that loved us and washed us from our sins in His own blood and has made us kings and priests unto God and His Father; to Him be glory and dominion forever and ever. Amen.” “Unto Him that loved us and washed us.” Loved us and washed us—carry those two words home with you—let them lie upon your tongue to sweeten your breath for prayer and praise. “Unto Him that loved us, and washed us, be glory and dominion forever and ever.”

Then John tells of the dignity which the Lord has put upon us in making us kings and priests. And from this he ascribes royalty and dominion unto the Lord, Himself. John had been extolling the Great King, whom he calls, “The Prince of the kings of the earth.” Such, indeed, He was and is and is to be! When John had touched upon that royalty which is natural to our Divine Lord and that dominion which has come to Him by conquest—and by the gift of the Father as the reward of all His travail—he then went on to note that He has “made us kings.” Our Lord’s royalty He diffuses among His redeemed! We praise Him because He is, in Himself, a King and next, because He is a king‐maker, the fountain of honor and majesty! He has not only enough of royalty for Himself, but He hands a measure of His dignity to His people. He makes kings out of such common stuff as He finds in us poor sinners! Shall we not adore Him for this? Shall we not cast our crowns at His feet? He gave our crowns to us—shall we not give them to Him? “To Him be glory and dominion forever and ever. Amen.” King by Your Divine Nature! King by filial right! King‐maker, lifting up the beggar from the dunghill to set him among princes! King of kings by the unanimous love of all Your crowned ones! You are He whom Your brethren shall praise! Reign forever and ever! Unto You be hosannas of welcome and hallelujahs of praise! Lord of the earth and Heaven, let all things that are, or ever shall be, render unto You all glory in the highest degree! ~ C.H. Spurgeon
