the obvious instances where Jesus speaks about Jonah, the example of the OT prophet seems to cast its shadow in other ways across Jesus' ministry.
Take the elder brother in Luke 15 - his mean-spirited response to the return of his brother is very much akin to Jonah's response to the repentance of Nineveh. And, just as the book of Jonah ends with the Creator's question, so too the parable ends with the Father's question.
And then there's the small matter of sleeping through a storm (Jonah 1:4ff; Mark 4:35ff). One slept in open defiance of his God, the other in secure trust in his Father and in glad submission to his calling.
Wonder if this same pattern emerges anywhere else?
