Hebrews 9:13-14

13For if the sprinkling of [ceremonially] defiled persons with the blood of goats and bulls and the ashes of a [burnt] heifer is sufficient for the cleansing of the body,

14how much more will the blood of Christ, who through the eternal [Holy] Spirit willingly offered Himself unblemished [that is, without moral or spiritual imperfection as a sacrifice] to God, cleanse your conscience from dead works and lifeless observances to serve the ever living God?
