What does the Bible say about Christ as the sin offering?

In Leviticus 4, we see God's instruction regarding sin offerings, highlighting the need for a perfect sacrifice to atone for sin. This foreshadows Christ, who is the ultimate sin offering. Hebrews supports this by stating that the blood of bulls and goats cannot take away sin, but Christ's sacrifice is once-for-all, fulfilling what the law required. His sacrifice perfectly satisfies God's justice, making it unnecessary for further sacrifices. The Old Testament sacrifices were merely types and shadows pointing ultimately to Christ's coming, where His one sacrifice will put away sin forever.
