When Jesus Christ came as high priest, he went through the greater and more perfect tabernacle that is not man-made, that is to say, not a part of this creation. He did not enter by means of the blood of goats and calves; but he entered the Most Holy place once for all by his own blood, having obtained eternal redemption.
The blood of goats and bulls and the ashes of a heifer was sprinkled on those who were ceremonially unclean to sanctify them, so that they became outwardly clean. How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God.
For this reason Jesus Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance – now that he has died as a ransom to set them free from the sins committed under the first covenant.
In the case of a will, it is necessary to prove the death of the one who made it, because a will is in force only when somebody has died. It never takes effect while the one who made it is living. This is why even the first covenant was not put into effect without blood. When Moses had proclaimed every commandment of the law to all people, he took the blood of calves, together with water, scarlet wool and branches of hyssop, and sprinkled the scroll and all the people. He said,
"This is the blood that seals the covenant which the Lord made with you when he gave all these commands.” (Exodus 24 v 8)
In the same way, he sprinkled with the blood both the tabernacle and everything used in its ceremonies. In fact, the law requires that nearly everything be cleansed with blood, and without the shedding of blood there is no forgiveness. It was necessary, then, for the copies of the heavenly things themselves with better sacrifices than these. For Christ did not enter a man made sanctuary that was only a copy of the true one; he entered heaven itself, now to appear for us in God’s presence.
Nor did Christ enter heaven to offer himself again and again, the way the High Priest enters the Most Holy Place every year with the blood that is not his own. Then Christ would have had to suffer many times since the creation of the world. But now he has appeared once for all at the end of the ages to do away with sin by the sacrifice of himself. Just as man is destined to die once, and after that to face judgement, so Christ was sacrificed once to take away the sins of many people; and he will appear a second time, not to bear sin, but to bring Salvation to those who are waiting for him!
