Hebrews 9:13-17

13For if the blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that their bodies are clean, 14how much more will the blood of Christ, who through the eternal Spirit offered Himself unblemished to God, purify our1 consciences from works of death, so that we may serve the living God!

15Therefore Christ is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, now that He has died to redeem them from the transgressions committed under the first covenant.

16In the case of a will,2 it is necessary to establish the death of the one who made it, 17because a will does not take effect until the one who made it has died; it cannot be executed while he is still alive.
