Hebrews 9:11-15, 16-17, 23-26

But when the Messiah arrived, high priest of the superior things of this new covenant, he bypassed the old tent and its trappings in this created world and went straight into heaven’s “tent”—the true Holy Place—once and for all. He also bypassed the sacrifices consisting of goat and calf blood, instead using his own blood as the price to set us free once and for all. If that animal blood and the other rituals of purification were effective in cleaning up certain matters of our religion and behavior, think how much more the blood of Christ cleans up our whole lives, inside and out. Through the Spirit, Christ offered himself as an unblemished sacrifice, freeing us from all those dead-end efforts to make ourselves respectable, so that we can live all out for God.

Like a will that takes effect when someone dies, the new covenant was put into action at Jesus’ death. His death marked the transition from the old plan to the new one, canceling the old obligations and accompanying sins, and summoning the heirs to receive the eternal inheritance that was promised them. He brought together God and his people in this new way.

That accounts for the prominence of blood and death in all these secondary practices that point to the realities of heaven. It also accounts for why, when the real thing takes place, these animal sacrifices aren’t needed anymore, having served their purpose. For Christ didn’t enter the earthly version of the Holy Place; he entered the Place Itself, and offered himself to God as the sacrifice for our sins. He doesn’t do this every year as the high priests did under the old plan with blood that was not their own; if that had been the case, he would have to sacrifice himself repeatedly throughout the course of history. But instead he sacrificed himself once and for all, summing up all the other sacrifices in this sacrifice of himself, the final solution of sin.
