The Lord prepared the following 5 things for Jonah:
1) A storm
2) A great fish
3) A vine
4) A worm
5) A wind.
In the first 2 chapters Jonah is the unwilling servant of God and in the last 2 chapters he is the reluctant servant of God.
In the first part God deals with Jonah’s will. In the second part God deals with his heart, attitude and motives.
