To be a messenger of gospel

Jonah 3:1-10
The word of the Load came to Jonah a second time. Jonah obeyed the word of the Load and went to Nineveh. Nineveh was a very important city- a visit required three days.
On the first day, Jonah started into the city. He proclaimed:"Forty more days and Nineveh will be overturned"
The Nineveh believed God. They declared a fast, and all of them, from the greatest to the lest, put on sackcloth. So did as the king and his nobles.
When God saw what they did and how they turned from their evil ways, he had compassion and did not bring upon them the destruction he had threatened.
Why?
The Load gave Jonah second chance to execute his command, and Jonah obeyed it. And his messages produces a remarkable effect.
Believed God the action is repent what they did and turn from their evil ways.
The Load has compassion and did not bring upon them the destruction he had threatened. The Load hope the evil men turn from evil way and be saved.
Jonah walked one day and the people of Nineveh believed God, and the king of Nineveh issued a proclamation in Nineveh, so the all city knew this warning message.
How?
For us we need to do is proclaim the message to the people living the dark, let them repent and turn from evil ways.
The Load has compassion, he hope more people be save, he don't like them be perished.
I should expression my compassion to he evil men, I am a messenger of gospel is the Load has power to do it.
