Jonah is a rather reluctant prophet. He avoids God when he can and when he can't he proclaims God's call to repent with plenty of grumbling. Yet Nineveh does repent out of fear of God's retribution. Jesus also calls the people of Galilee to repent, but there is a big difference between Jonah and Jesus and the character of their call to repent.
