How do we know that Jesus' works fulfill Scripture?

The fulfillment of Scripture by Jesus is a pervasive theme throughout the Gospels. In John 18:8, Jesus mentions that the saying might be fulfilled, a reference to the divine assurance that all things spoken of Him in the Scriptures would come to pass. This connects to prophetic texts such as Psalm 109 and Isaiah 53. The very purpose of His earthly ministry was to fulfill God's Word, as He indicated to His disciples after His resurrection (Luke 24:27). Every act of Jesus, including His arrest and subsequent crucifixion, was a deliberate action orchestrated to fulfill the divine plan set before the foundation of the world.
