Although we may prefer to focus on God's love, mercy, and grace, God's justice is also a key part of His character. After Jonah is spit up onto the beach at the end of chapter two, God calls him once again to go to Nineveh and share the message He gives him. This time Jonah does so and the entire city repents and humbles themselves before God. It's important for us to recognize that God was planning to wipe out the city of Nineveh because of their evil. God is just and when he sees evil and chaos happening to His good creation, He will act in order to bring justice. However, God is also merciful and when the people of Nineveh humble themselves and turn from their evil He is also willing to forgive them and not destroy the city.
