Hebrews 9:14

"For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh; how much more shall the Blood of Christ, who through the Holy Spirit offered Himself without spot to God, purge your conscience from dead works, to serve the living God." For (he says) if "the blood of bulls" is able to purify the flesh, much rather shall the Blood of Christ wipe away the defilement of the soul. For that thou mayest not suppose when thou hearest the word "sanctifieth," that it is some great thing, he marks out and shows the difference between each of these purifyings, and how the one of them is high and the other low. And says it is so with good reason, since that is "the blood of bulls," and this "the Blood of Christ." Nor was he content with the name, but he sets forth also the manner of the offering. "Who" (he says) "through the Holy Spirit offered Himself without spot to God," that is, the victim was without blemish, pure from sins. For this is the meaning of "through the Holy Spirit," not through fire, nor through any other things. "Shall purge your conscience" (he says) "from dead works." And well said he "from dead works"; if any man touched a dead body, he was polluted; and here, if any man touch a "dead work," he is defiled through his conscience. "To serve" (he says) "the Living and true God." Here he declares that it is not possible while one has "dead works to serve the Living and true God," for they are both dead and false; and with good reason he says this.
