Kate led an excellent fast-pasec study on Jonah 4 in homegroup last week. Doing a high-level analysis of what God does and what Jonah does in each chapter reveals some interesting patterns.
1. God said go, Jonah said no...
God saved
2. Jonah prayed (desperately, gratefully), God saved...
3. God said go, Jonah said OK...
God saved
4. Jonah prayed (angrily), God provided...
Most importantly it shows how Jonah, the most numerically 'successful' prophet in the whole Bible is consistently the opposite of YHWH, which he even acknowledges in 4:3. What amazing mercy God shows - even while we were sinners Christ died for us, Jew and Gentile alike!
