5 That is why, when Christ came into the world, he said to God, "You did not want animal sacrifices or sin offerings. But you have given me a body to offer. 6 You were not pleased with burnt offerings or other offerings for sin.
7 Then I said, 'Look, I have come to do your will, OÂ God- as is written about me in the Scriptures.'" 8 First, Christ said, "You did not want animal sacrifices or sin offerings or burnt offerings or other offerings for sin, nor were you pleased with them" (though they are required by the law of Moses). 9 Then he said, "Look, I have come to do your will." He cancels the first covenant in order to put the second into effect.

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.
