It depends on one's beliefs. In the religious context, especially in the Judeo - Christian tradition, it is a true story. It has been passed down through generations as a significant part of the religious heritage. But if you look at it from a strictly scientific or rationalist point of view, it seems implausible. Yet, the power of the story lies not just in its historical accuracy (if you believe it is historical) but also in the moral and spiritual messages it conveys.
The 'Jonah big fish story' is from the Bible. Jonah was a prophet who tried to run away from God's command. God sent a big fish to swallow him. Jonah was in the belly of the fish for three days and three nights. Eventually, he repented and the fish spat him out.
One moral in the Jonah and Big Fish story could be the idea of second chances. Jonah was given a second chance after being in the belly of the fish. It tells us that no matter how far we've strayed or how much we've messed up, there's always a possibility for redemption and getting back on the right path.
Well, another aspect of the moral in this story could be about God's mercy. Even though Jonah was disobedient, God didn't abandon him. He was given a second chance when he was spat out by the fish. This teaches us that God is merciful and forgiving, and we should also be forgiving towards others.
Jonah received the order from God to go to Nineveh. However, Jonah decided to flee instead. He boarded a ship. During the voyage, a fierce storm hit the ship. The sailors, realizing that Jonah was the cause of the trouble, threw him into the sea. Then, a big fish came and swallowed Jonah. Inside the fish, Jonah prayed to God and changed his attitude. Eventually, the fish released Jonah, and he went to Nineveh to fulfill God's will.
Jonah received a command from God to journey to Nineveh. However, Jonah chose to flee in the opposite direction. As a consequence, God caused a large fish to engulf him. While in the fish's belly, Jonah repented and prayed. Miraculously, after three days, the fish vomited Jonah out, and he finally made his way to Nineveh as God had initially instructed.
The big fish in the big fish wedding ring story could be significant in terms of discovery. It could be that the discovery of the wedding ring in relation to the big fish is a metaphor for finding true love. Just as one might be surprised to find a precious item like a wedding ring in an unexpected place like with a big fish, the couple might have found their love in an unexpected way or at an unexpected time. The big fish then serves as a reminder of that special discovery.
Jonah was also someone who experienced God's power and mercy. After being swallowed by a big fish, he finally realized his mistake and went to Nineveh to preach as God had originally asked him. Through this journey, he was a witness to God's ability to discipline and also forgive.
I'm not sure which specific 'big fish small fish story' you mean. It could be a fable about the relationship between big and small fish in an ecological sense, like how they interact in a pond or ocean. Maybe it's about the big fish preying on the small fish or their coexistence.
