God in his compassion wanted to reach Nineveh to give them an opportunity to repent. Jonah preached and they repented. Instead of being happy, Jonah was angry. He was so angry he wanted to die. God used a plant to teach Jonah a lesson. Jonah went to sit down and see what would become of the city. God caused a plant to grow up overnight to shade Jonah from the sun. The next day, God sent a worm to kill the plant. Jonah was upset over the loss of the plant. God used this to ask Jonah if he (God) shouldn’t have compassion on the inhabitants of Nineveh.
