How do we know that Christ is the fulfillment of sacrificial lambs?

Christ's role as the fulfillment of sacrificial lambs is clearly established in both the Old and New Testaments. Isaiah 53 describes the suffering servant who would bear the iniquities of many, presenting a picture of substitutionary atonement that culminates in Christ's crucifixion. When John the Baptist proclaimed Jesus as the 'Lamb of God, which taketh away the sin of the world' (John 1:29), he affirmed the culmination of sacrificial types and shadows found in the Old Testament. The repeated theme of lamb sacrifice in the Mosaic Law, particularly the Passover lamb whose blood protected Israel from judgment, continually pointed toward Christ as the perfect and complete offering for sin. His atoning death and resurrection serve as the definitive fulfillment of God's plan for redemption.
