The Sign of Jonah - Matt Postiff
The point of the likeness between Jonah and Jesus is not death/resurrection, but the similar period of time in hidden in the belly of the fish/belly of the earth. So even if Jonah did not die and rise again, there is no reduction in significance of the similarity between the prophet’s fish sign and the resurrection sign of the Son of God. In the end, Jesus gave them a stupendous sign. But they still did not believe it, just like Luke 16:31 predicted.
We ended with this application point: Why ask God for something if you will still refuse to believe in Him?
