What does the Bible say about the Old Testament and its relevance to Christ?

The Old Testament serves as God's Word, pointing to Christ throughout its narratives and prophecies. Our Lord Jesus Himself affirmed its significance on the road to Emmaus, indicating that the Scriptures testify about Him. Understanding the Old Testament is essential for comprehending the New Testament, as the Gospel itself declares that Christ died for our sins according to the Scriptures. Thus, to grasp the fullness of Christ, one must engage with the Old Testament narratives and recognize how they foreshadow His coming and His redemptive work.
