Why is understanding the role of Christ in the Old Testament important?

The Old Testament is full of types, shadows, and prophecies that point to Jesus Christ. For instance, Moses, who was a mediator under the law, foreshadows Christ, the ultimate mediator of grace. When we read through the Old Testament, recognizing these connections highlights the continuity of God's plan for salvation, revealing that every part of scripture, from the Law to the Prophets, gradually unveils Christ's coming and His sacrificial work. Without this understanding, one may miss the central theme of the Bible, which is the glory of Christ's redemption.
