How do we know that Jesus fulfilled the Old Testament prophecies?

Throughout the New Testament, it is emphasized that Jesus' life and mission fulfilled numerous Old Testament prophecies. In Acts 1:16-20, Peter illustrates this by referring to the Psalms, showing that David spoke of Judas' betrayal long before it occurred. These fulfillments affirm the sovereignty of God and the reliability of Scripture. Jesus himself explained that His sufferings and the purposes of God were determined before the foundation of the world (Luke 22:22). This underscores that all events in the life of Christ were not coincidences but are deliberately orchestrated plans of God.
