Hebrews 9:13-14

For if sprinkling ceremonially unclean persons with the blood of goats and bulls and the ashes of a heifer restores their outward purity;

then how much more the blood of the Messiah, who, through the eternal Spirit, offered himself to God as a sacrifice without blemish, will purify our conscience from works that lead to death, so that we can serve the living God!
