Genre and Preaching Jonah

Ed Scott raises the important question of how one's understanding of the genre of Jonah influences the preaching of Jonah here. But unfortunately he does not really address the issue other than affirming the book's historicity. I agree with that the book reflects a historical event but that is not all there is to the issue of genre. And the issue is an important one as Steven Smith in Recapturing the Voice of God has pointed out, text-driven preaching not only preaches the text but also the genre of the text.
