“When God saw what they did and how they turned from their evil ways, he relented and did not bring on them the destruction he had threatened.” (Jonah 3:10)
The word of the LORD comes to Jonah a second time: go to the great city of Nineveh and proclaim to it the message I give you. Jonah obeys. He enters the city and proclaims: forty more days and Nineveh will be overthrown. The Ninevites believe God. A fast is proclaimed and all of them, from the greatest to the least, put on sackcloth. When Jonah's warning reaches the king of Nineveh, he rises from his throne, takes off his royal robes, covers himself with sackcloth and sits down in the dust. He issues a decree: let everyone call urgently on God. Let them give up their evil ways and their violence. When God saw what they did and how they turned from their evil ways, he relented and did not bring on them the destruction he had threatened.
The Catechism identifies the repentance of Nineveh as the most dramatic example of communal conversion in the Old Testament, cited by Jesus as the sign that will judge the generation that refuses to repent (CCC 1431).
Brothers and sisters, when God saw what they did, he relented. The repentance was not a feeling; it was an action: they turned from their evil ways and their violence. God saw what they did. Not what they felt or intended. The repentance that moves God is the repentance that changes behaviour. From the king on his throne to the animals in their stalls, Nineveh turned. One of the greatest revivals in history came from five words: forty more days and overthrown.
Lord God, give us the repentance of Nineveh: from the greatest to the least, turning from evil ways and violence. Through Christ our Lord. Amen.
