(5) Therefore, when He came into the world, He said:
“Sacrifice and offering You did not desire,
But a body You have prepared for Me.
(6) In burnt offerings and sacrifices for sin
You had no pleasure.
(7) Then I said, ‘Behold, I have come –
In the volume of the book it is written of Me –
To do Your will, O God.'”
(8) Previously saying, “Sacrifice and offering, burnt offerings, and offerings for sin You did not desire, nor had pleasure in them” (which are offered according to the law), (9) then He said, “Behold, I have come to do Your will, O God.” He takes away the first that He may establish the second. (10) By that will we have been sanctified through the offering of the body of Jesus Christ once for all.
The author of Hebrews is unknown but the audience of this letter is Jewish Christians, who are in danger of renouncing their commitment to Jesus Christ as Messiah. The author makes extensive use of scripture to argue that the Old Testament points to the utter finality of the sacrifice of Jesus Christ that effectively established the New Covenant. The writer of Hebrews clearly regards God as the author of Scripture.
In Chapter 10 of Hebrews, the author contrasted the substance of the once and for all blood sacrifice of Jesus crucified with the “shadow” repetitive sacrifices of the Old Testament. To leave Christ in Judaism would be to choose shadow over the real thing. Nothing could be said that would be more contrary to Jewish belief and law about the efficacy of repetitive sacrifice as opposed to the final and sufficient sacrifice of Christ. The Jews would not question the authority of the Old Testament and the author quotes Psalm 40 and Jeremiah to bolster his argument. The importance of these verses are to show that Hebrews is not coming up with a new idea of religion but simply saying the Scriptures have pointed to Jesus as the Messiah all along.
Jesus comes into the world as one who created the world and as one who has a specific purpose. The perfect obedience and perfect satisfaction demanded by God was fulfilled by Jesus. Jesus declared that not only had He come to do the Father’s will but to meet the demands of the Law with perfect righteousness – perfect obedience to the will of God. This was God’s plan of redemption.
