There remains one final surprise in the book of Jonah, and perhaps it is the most astounding of all: the prophet resents God’s mercy toward sinners. Why would someone act this way towards sinners and towards God? Chapter four peels back the layers of our own hearts to reveal the sin within.
What would you think if one of the many cruel leaders in our world suddenly changed his ways? What if he stopped oppressing the weak, ceased being unjust, and ended his violent aggressions against other nations? This is precisely what happened in ancient Nineveh. When God extended mercy towards the great city of Nineveh, the king and people repented. This chapter of Jonah gives us a picture of what it looks like when God extends mercy rather than judgment.
Jonah is a powerful short story with many twists and surprises. The main purpose is to teach us that God offers mercy instead of judgment towards undeserving sinners. In the first two chapters, we see how the prophet Jonah receives mercy even though he is a rebel who refuses to follow God.
