Once for all time he took blood into that Most Holy Place, but not the blood of goats and calves. He took his own blood, and with it he secured our salvation forever.
Under the old system, the blood of goats and bulls and the ashes of a young cow could cleanse people's bodies from ritual defilement.
Just think how much more the blood of Christ will purify our hearts from deeds that lead to death so that we can worship the living God. For by the power of the eternal Spirit, Christ offered himself to God as a perfect sacrifice for our sins.
