God comforts us by the oath He made to Christ, appointing Him our high priest forever after the order of Melchizedek.
Christ does His priestly work in the heavenly tabernacle, before the very throne of God.
Christ does not offer up to God the blood of animals as Aaron did.
Christ presents His Own blood once for all in the holy place! Hebrews first mentions the sacrificial blood of Jesus in verse 12 of chapter 9.
His is a better sacrifice! His is a far richer blood than that of the animals!
Christ is the only morally perfect sacrifice for sin. He is God of very God, and yet He is clothed in the humanity of His people. He is sinless and perfect, God's Lamb without spot or blemish.
Only one death of our Savior is required! Only one entrance before the heavenly mercy seat is needed!
But then Hebrews exclaims that, by His one sacrifice, Christ has obtained eternal redemption for us!
The sacrifice of Jesus is the great price paid to set us free from the curse of the law. It is the horrible cost borne by Christ to rescue us.
First, it cleanses our consciences from dead works.
Our dead works are rotten, corrupt works, no matter how we view them.
Our consciences are condemned by our sin and our corrupt deeds. No matter how we try to dress them up, all our "righteousnesses" are like filthy rags before God. Our consciences know that, though we would like to deny it.
But Christ's blood cleanses our consciences from filthy works!
The blood of Jesus sacrificed for us takes away the pollution of our guilt, by satisfying God's justice in our place. Therefore, our consciences are at peace with a holy God.
it also purges us from relying upon our works to make us righteous.
