“Jonah was very upset about this, and He became angry” (Jonah 4:1). After the high points of prayer (Jonah 2 and revival (Jonah 3), we come to this! This is pathetic. It’s more than being upset and angry. Jonah became suicidal (Jonah 4:8-9). Why? – There’s no good reason for him to feel like this. There are good reasons for him to rejoice in the Lord and give thanks to the Lord. What are we to say about this? “The heart is deceitful and desperately wicked. Who can know it?” (Jeremiah 17:9). There’s something else we must never forget – God knows the heart, and He can change it!
