101 For since the law has but a shadow of the good things to come instead of the true form of these realities, it can never, by the same sacrifices which are continually offered year after year, make perfect those who draw near. 2 Otherwise, would they not have ceased to be offered? If the worshipers had once been cleansed, they would no longer have any consciousness of sin. 3 But in these sacrifices there is a reminder of sin year after year. 4 For it is impossible that the blood of bulls and goats should take away sins. 5 Consequently, when Christ came into the world, he said, "Sacrifices and offerings thou hast not desired, but a body hast thou prepared for me; 6 in burnt offerings and sin offerings thou hast taken no pleasure.

7 Then I said, 'Lo, I have come to do thy will, O God,' as it is written of me in the roll of the book." 8 When he said above, "Thou hast neither desired nor taken pleasure in sacrifices and offerings and burnt offerings and sin offerings" (these are offered according to the law), 9 then he added, "Lo, I have come to do thy will." He abolishes the first in order to establish the second. 10 And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.

Commentary on Hebrews 10:1-10

(Read Hebrews 10:1-10)

The apostle having shown that the tabernacle, and ordinances of the covenant of Sinai, were only emblems and types of the gospel, concludes that the sacrifices the high priests offered continually, could not make the worshippers perfect, with respect to pardon, and the purifying of their consciences. But when "God manifested in the flesh," became the sacrifice, and his death upon the accursed tree the ransom, then the Sufferer being of infinite worth, his free-will sufferings were of infinite value. The atoning sacrifice must be one capable of consenting, and must of his own will place himself in the sinner's stead: Christ did so. The fountain of all that Christ has done for his people, is the sovereign will and grace of God. The righteousness brought in, and the sacrifice once offered by Christ, are of eternal power, and his salvation shall never be done away. They are of power to make all the comers thereunto perfect; they derive from the atoning blood, strength and motives for obedience, and inward comfort.
