The book of Job is a poem that highlights the eternal search for answers. You are right: It's not a literal account like the JWs believe.
For instance, I noted that people were debating on how the Tanakh seemed to contradict itself by having Satan the Devil in heaven having a conversation with G-d. This is not what Jews read from the text at all, especially from the original Hebrew. (Many Jews don't believe there is a person such as "Satan the Devil." Christianity on the other hand is obsessed with this creature.)
In Job 1 and 2, G-d is discussing with the heavenly court the issue of Job's faithfulness. One member of the court plays the part of logic, asking opposing questions and setting up a test to help supply a valid answer to what has been raised. The term for this arguing person of logic in Hebrew is "ha satan," the "opposer." It isn't an evil spirit, however, just someone arguing a point to show that the Hebrew G-d is one who strives to come to conclusions fairly.
When the protagonist Job finds himself in the middle of his test, he demands answers, the main one being: Why? And he wants to hear from none other than the Creator.
But when G-d does finally speak to Job as requested, G-d offers no answers. G-d does, however, remind Job that G-d transcends our ability to fully comprehend our Creator. And then the account ends on a happy note.
It's a lesson in life we all must learn. Life is full of mysteries. The existence of G-d does not equate full comprehension of G-d by G-d's creation. G-d transcends, cannot be defined, and sometimes we have to search for and even make up our answers to questions we have.
Jews learn various lessons from this story (again not a literal tale). One is that Job doesn't do anything to make his life better. All he does is complain. That doesn't do him any good. G-d proves that Job's course has been one of folly, spending all his time wanting to know things that probably wouldn't matter in the end since Job is not a baby. He can do something to get out of his predicament, and obviously finally does because of the way the story ends.
Another lesson is that suffering of itself doesn't disprove G-d's existence. This was a lesson many of us have had to learn again and again during the Spanish Inquisition and the Holocaust. The suffering of almost 2000 years ended with out being restored to our homeland after World War II and our recapturing Jerusalem in 1967. Like Job the situation of the Jews has turned around and G-d has not forsaken his people but is fulfilling what G-d has promised.
Finally, Job is a book not of answers but of questions. Life is filled with them. Debates abound. Miracles are few. There is suffering, loss, and renewal. All of these things come to us many times and many ways. This is the stuff of life. Job teaches us that our journey through life will be marked with questions and all the other trials and rewards that came to Job. Sometimes we hear from G-d, and sometimes when we do we don't get the answers we were hoping for. The story is a legend, but its lessons are realistic. You can't have all the answers, but that is no reason to stop living.
