From What is so Amazing about Grace Blog
God called Jonah for a specific mission. It was clear, God didn't leave any doubt. I want you to go and preach to the people in the capital city of your greatest enemy - Nineveh.
Jonah wasn't up for it and decided to go in the opposite direction. I can still remember my old friend William Dillon preaching on this by saying in his broad Northern Irish accent.
DOWN into the boat
DOWN into the bottom of the boat
DOWN into the stormy sea
DOWN into the belly of a great Fish"
Notice the common denominator.
Walking the opposite way from the direction of God leads to a downward spiral.
Only when Jonah looked UP did he go UP.
Literally he was thrown up.
