Pope Shenouda III
We notice these days that nations reason with each other according to the standard: heads of state with heads of state, kings with kings, prime ministers with prime ministers, ambassadors with ambassadors, consuls with consuls,
. It can never happen that a head of state would talk with a chairman or a secretary of a governorate. He would say that such a person is not up to the level to negotiate with me. He can negotiate with a person of his standard.
But God did not do that with Jonah. He did not say: "I will not reason with him directly. I can send him an angel or a prophet like him! Or send him another whale to reason with him! But God condescended to reason with Jonah, and reason with him directly with no mediator, and convince him.
