How does Jonah's story relate to the doctrine of substitutionary atonement?

Jonah's story highlights the doctrine of substitutionary atonement, where Jonah, although rebellious, willingly offers himself for the sailors' safety, akin to Christ's sacrifice for humanity. When Jonah says to throw him into the sea to calm the storm, it symbolizes Christ giving Himself for our sins, bearing the penalty we deserve. The narrative not only illustrates our need for a substitute but also points to Christ as the ultimate fulfillment of this atonement. The act of throwing Jonah overboard and the resulting calm mirrors Christ's sacrificial death that brings peace with God for all who believe.
