How do we know that Jesus' death fulfilled God's promises?

The fulfillment of God's promises through Jesus’ death is illuminated in various Scripture passages. For instance, John 19:36 reiterates the prophecy stating that 'a bone of Him shall not be broken,' connecting Jesus to the Passover lamb from Exodus 12:46. Furthermore, Zechariah 12:10 prefigures the piercing of Jesus' side, which occurred when a soldier thrust a spear into Him after His death. This act of piercing is a direct fulfillment of prophecy and serves to validate His identity as the Messiah. Each detail of His crucifixion, including the unbroken bones and the piercing, illustrates God's sovereign plan and the truth of His Scriptures.
