Hebrews 10:14-18

For by one sacrifice he has made perfect forever those who are being made holy. The Holy Spirit also testifies to us about this. First he says: “This is the covenant I will make with them after that time, says the Lord. I will put my laws in their hearts, and I will write them on their minds.” Then he adds: “Their sins and lawless acts I will remember no more.” And where these have been forgiven, sacrifice for sin is no longer necessary.
