Every priest goes to work at the altar each day, offers the same old sacrifices year in, year out, and never makes a dent in the sin problem. As a priest, Christ made a single sacrifice for sins, and that was it! Then he sat down right beside God and waited for his enemies to cave in. It was a perfect sacrifice by a perfect person to perfect some very imperfect people. By that single offering, he did everything that needed to be done for everyone who takes part in the purifying process. The Holy Spirit confirms this:
Ever feel guilty for sins you have confessed in the past that are supposed to be forgiven and forgotten by God? Do you feel bad, even though you have accepted Jesus as your personal Savior and often tell others of His life-saving sacrifice on the Cross of Calvary? Perhaps Satan is busy putting messages in your head of a false doctrine of works or hinting that you are too far gone to have been saved?
Over and over, time and time again the message of God’s grace is plain and simple: For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. – Ephesians 2:8-9 (ESV)
