Christ's sacrifice is the immortality of the redeemed by his blood. The blood of Christ was shed on a heavenly altar, where redemption was provided once and for all.

From the garden of Eden, to the garden of heavenly paradise, the blood of sacrifice constitutes the permanent testimony of God's grace. Just as the fallen man was dressed in the skins of animals sacrificed by God Himself (Genesis 3:21), the blood of the Lamb was shed to clothe God's justice to those who accept to receive this grace. This is the song of those who make this covenant with God through "sacrifice."

The letter to the Hebrews contrasts God's covenants through Moses and Christ. The Mosaic Covenant allowed animal sacrifices that provided temporary relief to man's guilt, and offered lessons on God's justice. The covenant of Moses provided a bond with God through the blood of animals. However, these sacrifices were to be repeated annually in the tabernacle, which was only a symbol of God's eternal and heavenly altar. But Jesus Christ entered history as an eternal priest to offer an eternal sacrifice for sin. The shedding of his blood provided a sacrifice and a permanent link between God and human beings. His blood was shed not only on an earthly altar, but before the true altar of God in heaven, where he obtained redemption for the sin of all who receive him as his Lord and Savior. The immutable bond established through the new covenant in the blood of Christ, the definitive realization of the promise of the just and at the same time merciful God.

11 But when Christ is already present, the high priest of the coming years, by the most complete and perfect tabernacle, not made of hands, that is, not of this creation, 12 and not by the blood of goats or calves, but by his own blood, he entered once and for all in the Most Holy Place, having obtained eternal redemption (Hebrews 9: 11-12).
