How do the Old Testament prophets relate to Christ?

In 1 Peter 1:10-12, it is made clear that the prophets of old diligently sought to understand the salvation that was to come through Christ, focusing on His sufferings and the glory that should follow. They were inspired by the Spirit of Christ, who revealed to them these truths concerning the future Messiah. This indicates that the entire Old Testament points towards Christ, and their prophecies prepared the way for the fullness of God's revelation in Him. Thus, they serve as a vital link between God's plan throughout history and the ultimate fulfillment in Jesus.
