Hebrews 9:14-15

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.
