Hebrews 9:13-14

According to the Law of Moses, those people who become unclean are not fit to worship God. Yet they will be considered clean, if they are sprinkled with the blood of goats and bulls and with the ashes of a sacrificed calf. But Christ was sinless, and he offered himself as an eternal and spiritual sacrifice to God. This is why his blood is much more powerful and makes our consciences clear. Now we can serve the living God and no longer do things that lead to death.
