Hebrews 9:11-14

But Christ having come a high priest of the good things to come, through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation, nor yet through the blood of goats and calves, but through his own blood, entered in once for all into the holy place, having obtained eternal redemption. For if the blood of goats and bulls, and the ashes of a heifer sprinkling them that have been defiled, sanctify unto the cleanness of the flesh: how much more shall the blood of Christ, who through the eternal Spirit offered himself without blemish unto God, cleanse your conscience from dead works to serve the living God?
