How do we know that Christ is central to all scripture?

We ascertain that Christ is central to all scripture through explicit declarations found within the texts themselves. For example, Romans 1:1-4 states that the gospel concerns God's Son, Jesus Christ, who is the fulfillment of the prophets' writings. Jesus Himself indicated that all scriptures testify about Him, as seen in Luke 24:27, where He teaches that the Scriptures reveal truths about His identity and mission. Additionally, throughout the Old Testament, types and shadows point toward the ultimate reality found in Christ. This understanding solidifies the conviction that every book of the Bible, including Revelation, ultimately has the purpose of revealing God’s Son to His creation.
