What happened when Jonah finally went to Nineveh after the fish experience?
After the fish pitched Jonah back onto shore, he went to the Gentiles. When he finally went to Nineveh, the city repented in sackcloth and ashes. This occurred only after his death, burial, and resurrection in type, making him a fit servant for that mission.
Les explains that after three days and three nights, the fish pitched Jonah back onto shore, bringing him back to life for all practical purposes—a type of resurrection. Only after experiencing death, burial, and resurrection in type could Jonah go to the Gentiles, and that is where he went. When he finally went to Nineveh, the city repented in sackcloth and ashes. Les points out that Jonah was not a fit servant until he had fulfilled the type, and Jesus uses this to show that until He experienced death, burial, and resurrection, He could not be the object of faith for the mass of the Gentile world. But He has.
