When God calls you, he does not discuss or make a proposal. It is not for discussion. God had a task for Jonah, but he decided to run away and thereby endangering the people who were with him. Jonah 1:4 But the LORD sent out a great wind on the sea, and there was a mighty tempest on the sea, so that the ship was about to be broken up.
God can use anything to accomplish His mission. Jonah 1:17 Now the LORD had prepared a great fish to swallow Jonah. And Jonah was in the belly of the fish three days and three nights.
