"The word of Yahweh was addressed to Jonah a second time. 'Up' he said, 'Go to Nineveh, the great city, and preach to it as I shall tell you.' Jonah set out and went to Nineveh in obedience to Yahweh." (Jonah 3: 1-3)
The word of Yahweh is addressed to the prophet a second time. To which 'city' is the Lord sending me? What message does he want me to preach?
Father, I will go wherever you send me. I will say exactly what you want me to say. Jonah obeyed the Lord and delivered the message of the Lord. The result was a rich harvest.
"And the people of Nineveh believed God; they proclaimed a fast and put on sack cloth, from the greatest to the least." (Jonah 3: 5)
I observe here a principle of apostolic productivity: Cast the net where Jesus asks you to do so.
