God assigned and appointed that big fish for a specific task…to gulp Jonah down and carry him around in its belly until Jonah changed his mind about the people of Nineveh. There are three interesting theories concerning this fish. Did God pick a fish already in existence to carry out His plan for Jonah? Or did He instantly create that fish the moment He needed it? Or was that fish created way beforehand for the sole purpose of swallowing Jonah at some point in the future? Any way you think about it, God’s creativity is boundless…His imagination endless.
