Hebrews 10:9-18

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! Yet every day priests still serve, ritually offering the same sacrifices again and again—sacrifices that can never take away sin’s guilt. But when this Priest had offered the one supreme sacrifice for sin for all time he sat down on a throne at the right hand of God, waiting until all his whispering enemies are subdued and turn into his footstool. And by his one perfect sacrifice he made us perfectly holy and complete for all time! The Holy Spirit confirms this to us by this Scripture, for the Lord says, “Afterwards, I will give them this covenant: I will embed my laws into their hearts and fasten my Word to their thoughts.” And then he says, “I will not ever again remember their sins and lawless deeds!” So if our sins have been forgiven and forgotten, why would we ever need to offer another sacrifice for sin?
