How do we know that Jesus fulfills the role of a substitute like Jonah?

The account of Jonah being thrown into the sea parallels Jesus Christ's ultimate sacrifice on the cross. Just as Jonah was cast into the stormy sea to calm it and save those aboard the ship, Jesus willingly bore the wrath of God to save His people from their sins. This typology fulfills the prophetic nature of Jonah's experience, indicating that Jesus’ suffering and death were necessary for the redemption of humanity. By understanding Jonah's role, we gain insight into the greater sacrifice of Christ, who came to give His life as a ransom for many, emphasizing the core truth of substitutionary atonement central to Reformed theology.
