How do we know that the Scriptures testify about Jesus?

In John 5:39, Jesus instructs the religious leaders to search the Scriptures, for they testify of Him. This underscores the belief that the entirety of Scripture is centered on the person and work of Jesus Christ. The prophecies, laws, and historical accounts presented in the Old Testament provide not only context but also an expectation for His coming. Christ’s fulfillment of these Scriptures serves as a profound confirmation of their authenticity and reveals that their ultimate purpose is to point to the saving work of the Messiah. This recognition is vital for understanding the Gospel and grounding faith in Christ, as it shows how the narrative of redemption unfolds throughout the biblical text.
