How do we know Jesus is the ultimate sacrificial Lamb in the Scriptures?

Throughout the Bible, particularly in the Old Testament, the imagery of sacrifice points to a need for atonement for sin. John 1:29 refers to Jesus as the Lamb of God who takes away the sin of the world. The story of Abraham and Isaac foreshadows this, where God provides a ram in place of Isaac, illustrating that He would one day provide His Son as the ultimate sacrifice. In Luke 21, the widow’s offering is also symbolic, demonstrating the kind of offering God desires—one that comes from the heart. Therefore, when we behold the sacrificial acts in the Scriptures, they ultimately lead to the realization of Jesus as the singular and sufficient Lamb who fulfills all sacrificial requirements.
