Hebrews 9:13-14

13The old rules said that the priest must use the blood of goats or bulls to make people clean. Or he could burn a young cow and mix the ashes with water. He would then splash the blood or the ashes over the people who were unclean. Then those people became clean again in their bodies, and they could worship God.

14But the blood of Christ's sacrifice will do much more than that! Christ offered himself to God, in the power of his Spirit, who lives for ever. That sacrifice was completely good. There was no wrong thing in Christ. He offered his own blood to make us completely clean inside ourselves. We no longer have to do things that lead to death. Instead, we can serve the God who lives for ever.
