Jonah's anger at God's mercy towards the Ninevites reveals a deeper issue within him—a lack of compassion and an inflated sense of self-righteousness. He is more concerned with his reputation and personal comfort than with the salvation of an entire city. This is a reminder that God's ways are higher than ours, and His mercy extends beyond our understanding. God's questions to Jonah are not for His own knowledge but to prompt Jonah to reflect on his heart's condition. These questions challenge us to examine our own attitudes towards God's mercy and our willingness to extend it to others.
