Hebrews 9:12-15

9:12 and he entered once for all into the most holy place not by the blood of goats and calves but by his own blood, and so he himself secured eternal redemption. 9:13 For if the blood of goats and bulls and the ashes of a young cow sprinkled on those who are defiled consecrated them and provided ritual purity, 9:14 how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our consciences from dead works to worship the living God.

9:15 And so he is the mediator of a new covenant, so that those who are called may receive the eternal inheritance he has promised, since he died to set them free from the violations committed under the first covenant.
