Who His own self bare our sins in His own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed. – 1 Peter 2:24

The very best way to describe the death of our Lord is to call it “the sacrifice of Himself.” It may be well rightly to divide the sacrifice, as the priest cut up the bullock or the ram. You may speak of our Lord’s bodily sufferings, His mental griefs, and His spiritual anguish; but for the most part we are not able to go far in this detailed appreciation of the wondrous sacrifice. We are such poor folk in spiritual things, that instead of bringing a bullock which could be anatomized and its vital organs all laid bare, we are content to bring a pair of turtle doves, or two young pigeons; and these were not carefully divided asunder, but burned upon the altar. The most of us have to take our Lord Jesus Christ as a whole; since, from want of understanding, we cannot go into detail. What did He offer to God? He made a sacrifice of Himself. Truly He sacrificed His crown, His rest, His honor, His reputation, and His life; but the essence of the sacrifice was Himself: Himself took our iniquity, and bare our sorrows. “He His own self bare our sins in His own body on the tree.” Thy sacrifice, O Christ, is not to be measured unless we could compute the infinity of Thy Godhead. It was not only Thy labor, Thy pain, Thy shame, Thy death; Thy sacrifice was Thyself; what more couldest even Thou offer? There, on the altar, the Son of God did place Himself, and there He bled and died that He might be the victim of punitive justice, the substitute for guilty men. There was He unto God a sweet-smelling savor, because He vindicated the law, and made it possible for the Lawgiver to be justly merciful. ~ C.H. Spurgeon
