Hebrews 10:9-10, 14

And then he said, “God, I will be the One to go and do your will.” So by being the sacrifice that removes sin, he abolishes animal sacrifices and replaces that entire system with the new covenant. By God’s will we have been purified and made holy once and for all through the sacrifice of the body of Jesus, the Messiah!

And by his one perfect sacrifice he made us perfectly holy and complete for all time!
