How do we know that Jesus is the fulfillment of Old Testament sacrifices?

The New Testament frequently affirms that Jesus is the fulfillment of all Old Testament sacrifices. In Genesis 22, the narrative foreshadows Christ's ultimate sacrifice as God provides a ram for Abraham instead of Isaac, illustrating the concept of substitution. Jesus is identified in John 1:29 as the 'Lamb of God who takes away the sin of the world,' directly connecting Him to the sacrificial system established in the Old Testament. Additionally, Hebrews 10:10 emphasizes that through the offering of Jesus Christ, we are sanctified once and for all, confirming that He completes what the preceding sacrifices could only symbolically represent. The sacrificial system points to Christ as the ultimate fulfillment of God's redemptive plan.
