When God relents from destroying Nineveh, Jonah accuses Him of doing a “great evil.” Jonah sits outside the city to see what will come of it — hoping God might change his mind and rain fire down upon Nineveh. God appoints a plant to provide shade and comfort for Jonah, but the next day God appoints a worm to eat the plant, and then sends a scorching east wind. Like Jonah, we can hang on to a root of bitterness and anger toward God when things don’t go our way. God will often send things into our life that eat away at our comfort, but it is for our good — that we might be purified by God.
