What does the Bible say about God's mercy in Jonah?

The Book of Jonah vividly demonstrates God's boundless mercy, as evidenced by His decision to send Jonah to preach to the wicked city of Nineveh. Despite Jonah's initial resistance, God's purpose was to extend grace to these pagans. When the people, led by their king, repented and turned from their evil ways, God had compassion and chose to spare the city from destruction. This reflects the core theological tenet that no one is beyond the reach of God's grace when they come to Him with genuine repentance and faith, underscoring the stunning reality that God desires all to come to repentance, as seen in His actions throughout Scripture.
