Out of the mouth of a fish

Today, i read the book of Jonah. I'm not much of the bible reading sort but the book interested me in its dealings with mercy and the value of life. Sometimes, we can be to quick to make judgment on others. Furthermore, i found it interesting that god "repented" for his quick judgment against Nineveh. Meaning, that god himself makes mistakes. although some would argue that a perfect god new that in order to instruct a lesson he must demonstrate superior mercy through repentance of his perfect ways. Who knows?
