Jonah was inside the belly of a large fish, praying for God’s mercy. He learned to obey God’s leading.
“All who worship worthless idols turn from the God who offers them mercy.” Jonah 2:8
Though, if Jonah had not gone to Ninevah, would the people have repented and turned to God? Pray that God’s message would be speaking to someone who would follow God’s leading.
“How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them?” Romans 10:14
