Since Christ took the book of Jonah literally, any attack on the book (or on THE Book) is an attack on the deity of Christ and is not to be countenanced by people who love the Lord.
We need not trouble ourselves about the unbelieving theologians' contention that the book is a combination of allegory and myth.
To Jonah "the word of the Lord came"! (hALLELEUJAH!) This and similar expressions occur seven times in his book (1:1; 2:10; 3:1,3; 4:4,9,10). Again and again we read, "God said," but the liberal says He didn't.
God speaks truth, and the liberal is a liar.
