And hast made us unto our God kings and priests; and we shall reign on the earth.- Revelation 5:10

They who stand before the throne sing of the Lamb-the Lion of the tribe of Judah, who took the book and broke the seals thereof-” Thou hast made us kings and priests unto our God.” In heaven they do not sing

“Glory, honor, praise, and power
Be unto ourselves for ever;
We have been our own Redeemers; Hallelujah!”

They never sing praise to themselves; they glorify not their own strength; they do not talk of their own free-will and their own might; but they ascribe their salvation, from beginning to end, to God. Ask them how they were saved, and they reply, “The Lamb hath made us what we are.” Ask them whence their glories came, and they tell you, “They were bequeathed to us by the dying Lamb.” Ask whence they obtained the gold of their harps, and they say, “It was dug in mines of agony and bitterness by Jesus,” Inquire who stringed their harps, and they will tell you that Jesus took each sinew of His body to make them. Ask them where they washed their robes and made them white, and they will say-

“In yonder ‘fountain filled with blood,
Drawn from Immanuel’s veins.'”

Some persons on earth do not know where to put the crown; but those in heaven do. They place the diadem on the right head; and they ever sing, ” And He hath made us what we are.” ~ C.H. Spurgeon
