How do we know the doctrine of redemption through Christ is true?

The doctrine of redemption through Christ is affirmed by the consistent testimony of Scripture, which portrays the Lamb as typified, prophesied, applied, and ultimately personified in Jesus. For instance, in Genesis 22, Abraham prophesies that God will provide a lamb, pointing to Christ. In Exodus 12, the Passover lamb prefigures the sacrifice of Christ, showing how God’s people were saved through the blood applied to their doorposts. The culmination of this doctrine is found in Isaiah 53, where the suffering servant is described as bearing the sins of many. These prophetic fulfillments validate the truth of redemption through Christ, demonstrating it as a central tenet of the Christian faith.
