2 If they had, the worshipers would have gone merrily on their way, no longer dragged down by their sins. 3 But instead of removing awareness of sin, when those animal sacrifices were repeated over and over they actually heightened awareness and guilt. 4 The plain fact is that bull and goat blood can't get rid of sin. 5 That is what is meant by this prophecy, put in the mouth of Christ: You don't want sacrifices and offerings year after year; you've prepared a body for me for a sacrifice.

Matthew Henry's Commentary on Hebrews 10:2-5

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.
