For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the ones approaching perfect. For then would they not have ceased to be offered? because the worshipers once purged should have had no more consciousness of sins. But in those sacrifices there is a remembrance again made of sins every year. For it is not possible that the blood of bulls and of goats should take away sins. (Hebrews 10:1-4)
