How do we know Jesus Christ is the ultimate sacrifice?

Jesus Christ is recognized as the ultimate sacrifice because He fulfills the types and shadows depicted in the Old Testament. The red heifer, for example, was to be without blemish and never subjected to a yoke, mirroring Christ's sinless nature and His unique role in bearing the sins of His people. In Hebrews 9:12, it states that Christ entered the holy place, securing eternal redemption through His own blood, distinguishing Him from the repeated sacrifices of the Old Covenant. This confirms the finality of Christ's sacrifice as the complete and perfect atonement for sin, which no animal could achieve.
