How does the Old Testament illustrate Christ's redemption?

The Old Testament contains numerous illustrations of Christ's redemptive work, often depicted through types and shadows. For instance, the role of the High Priest, who represented the people of Israel before God and offered sacrifices for their sins, foreshadows Christ's ultimate sacrifice. Hebrews 4:14-16 emphasizes that Christ is our great High Priest who has passed into the heavens. His role fulfills the sacrificial system established in the Old Testament, demonstrating God’s continuous plan for redemption leading to Christ's coming.
