One-paragraph commentary on Jonah

In his online class notes, Dr. Conrad Gempf has posted what amounts to the best one-paragraph commentary I've ever seen on the book of Jonah:

The most important message of this book is that God is more willing to give second chances -- to wait for his people -- than people are. The scale of self-deprecating humour in the book is astounding. There's only one Jew in the book and he is the only person in the book who doesn't respond properly to God. Even the feared and despised Assyrian Ninevites hear and obey. I'll bet this book and its author were as roundly condemned by the religious Jews of his time as Jesus was in his.

I'll bet Conrad is right.
