How do we know the doctrine of Christ's supremacy in the Bible is true?

The doctrine of Christ’s supremacy is well-supported by the unity and continuity of Scripture. In John 5:39, Jesus directly attests that the Scriptures testify about Him, urging us to see Him as the focal point of the Bible. The Old Testament is filled with prophetic images and types that foreshadow His coming, such as the Passover lamb in Exodus and the suffering servant in Isaiah. These elements point towards His sinless life, sacrificial death, and resurrection.

Furthermore, the New Testament writers confirmed who Christ is by referring to these earlier Scriptures. From Matthew to Revelation, Christ is presented not only as a historical figure but as the incarnate Word, whose nature as both God and man bridges humanity’s relationship with the Father. This consistent portrayal across both Testaments assures us that He is indeed the central message of the entire biblical narrative.
