NOTES for Heb 9:11-12
In the new messianic covenant-union, the person of the Messiah Himself as High Priest plays the decisive role, for He can cleanse those who trust Him in a way no cleansing sacrifices of former times could cleanse them. Yahwistic cleansing sacrifices really could deliver a sinner from the consequences of the sin he had committed, if the sin had been committed unintentionally, but only until the next sin. With his sin a person remained alone before God and had to think for himself what to do with his sinfulness. It is not so with Christ: He does not leave the sinner who has trusted Him alone with his sin before God.
He Himself takes upon Himself the consequences of the sin committed by the person, if only the person agrees to this and if he repents of his sin. He not only brought the Kingdom into the world; He also helps everyone who seeks to enter it, regardless of the past, regardless of the sins that could have hindered a person on his path.
Formerly a person could be cleansed for a time, for a time return to the state in which he could approach the altar and be sanctified. But such a state could not be permanent; a person was sanctified, and then rolled back again, sinned again, repented again, performed cleansing sacrifices again, and again went to the altar so that, having been sanctified, he would then roll back again. The rollback was inevitable: sin held the person in its power, never releasing him completely into freedom.
Sometimes the chain became longer, and then an illusion of liberation arose, but sooner or later the person again discovered its end, realizing that he still had no real freedom. With Christ it is not so: He breaks the chains binding us completely - at the cost of His own life, which He gives for the possibility of freeing from the power of sin everyone who is ready to allow Him to do this and who is ready to ask Him for it. Here liberation is no longer for a time, but forever. And there is the possibility of true, full life in the Kingdom, which without Him we would not have, not only because there would be no Kingdom in the world, but also because we would never be able to contain its life.
