What does the Bible say about the atoning sacrifice of Jesus?

The atoning sacrifice of Jesus is central to the gospel message, as highlighted in Hebrews 9:11-12. It emphasizes that Christ did not enter the holy place with the blood of goats and calves but by His own blood, obtaining eternal redemption for us. His sacrifice deals definitively with sin, ensuring that 'thy sins and thy iniquities will I remember no more' (Hebrews 8:12). This indicates that believers are fully pardoned and that their sins can never be brought against them again. This is made possible because Christ, as our high priest, fulfilled all the requirements of the law and provided a complete and perfect sacrifice for our sins.
