Because of Christ, the work is done for our salvation through His perfect sacrifice. Hebrews 9:14 says, How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God! We are no longer expected to work and go through the work of sacrifices through priest for the atonement of our sins. Christ was the perfect sacrifice once and for all. We must learn to live in that state of cleared conscience He has provided us.
