How do we know that Jesus is the fulfillment of the Old Testament prophecies?

The fulfillment of Old Testament prophecies is evident throughout Jesus' earthly ministry. For instance, in Luke 11, Jesus alludes to Jonah, presenting Himself as the greater prophet who provides the ultimate sign of His redemptive purpose. Peter, in Acts 2, reaffirms this by stating that Jesus was delivered up according to God's predetermined plan, fulfilling the prophetic scriptures concerning His suffering and resurrection. Each miracle, teaching, and aspect of His life serves to substantiate His messianic identity, revealing Him as the culmination of God’s revelation through the prophets, demonstrating that God's sovereign plan unfolds perfectly in Christ.
