How does the Old Testament relate to the gospel?

The Old Testament provides a foundational backdrop for the gospel, presenting prophetic Scriptures that foreshadow the coming Messiah and His work of redemption. As Paul states in 1 Corinthians 15:3, 'Christ died for our sins according to the Scriptures.' This indicates that the entirety of the gospel is rooted in God’s redemptive plan revealed throughout the Old Testament. From the sacrificial system initiated in the Law to prophecies like Isaiah’s suffering servant, these Scriptures foretell the necessity of Christ’s death and resurrection. Understanding this connection enriches the believer’s appreciation of the gospel and underscores that salvation history is woven throughout God's word.
