4. It is the blood of Christ, who offered himself to God, _without spot_. This was a perfect sacrifice. The victim was without blemish or defect; the altar was complete in all its appurtenances; and the high-priest possessed every conceivable qualification for his work. Christ was at once victim, altar, and high-priest; “holy, harmless, and undefiled;” “God manifest in the flesh.” Being himself perfect God, and perfect man, and perfect Mediator between God and man, he perfects for ever all them that believe. 5. It is the blood of Christ, who offered himself to God, without spot, _through the eternal Spirit_. By the eternal Spirit here, we are to understand, not the third person of the Godhead, but the second; Christ’s own Divine nature, which was co-eternal with the Father before the world was; and which, in the fulness of time, seized on humanity, sinless and immaculate humanity, and offered it body and soul, as a sacrifice for human sins. The eternal Spirit was at once the priest that offered the victim, and the altar that sanctified the offering. Without this agency, there could have been no atonement. The offering of mere humanity, however spotless, aside from the merit derived from its connection with Divinity, could not have been a sacrifice of sweet-smelling savor unto God. 6. It is the blood of Christ, who offered himself to God, without spot, through the eternal Spirit, _that he might purge your conscience_. As the typical sacrifices under the law purified men from ceremonial defilement, so the real sacrifice of the Gospel saves the believer from moral pollution. Blood was the life of all the services of the tabernacle made with hands, and gave significance and utility to all the rites of the former dispensation. By blood the covenant between God and his people was sealed. By blood the officers and vessels of the sanctuary were consecrated. By blood the children of Israel were preserved in Egypt from the destroying angel. So the blood of Christ is our justification, sanctification, and redemption. All the blessings of the gospel flow to us through the blood of the Lamb. Mercy, when she writes our pardon, and when she registers our names in “the Book of Life,” dips her pen in the blood of the Lamb. And the vast company that John saw before the throne had come out of great tribulation, having “washed their robes and made them white in the blood of the Lamb.” The children of Israel were delivered from Egypt, on the very night that the paschal lamb was slain, and its blood sprinkled upon the doorposts, as if their liberty and life were procured by its death. This typified the necessity and power of the atonement, which is the very heart of the gospel, and the spiritual life of the believer. In Egypt, however, there was a lamb slain for every family; but under the new covenant God has but one family, and one Lamb is sufficient for their salvation.
