It may certainly appear the book of Job is written to be a parable, play, fable or legend where we see all the behind-the-scenes discussions along with the playing out of corresponding events. However, the book of Job is an actual account of a man named Job who was tested by God, and—as a result of his trial—comes to a clearer understanding of his Creator.
Even if the account of Job was written as a fable, we know the Word of God is God-breathed, “profitable for teaching, for reproof, for correction and for training in righteousness” (2 Timothy 3:16), so we know it’s importance would not be diminished. Regardless, we know Job was a real person. Ezekiel 14, verses 14 and 20 refer to Noah, Daniel and Job. We know Daniel was a historical person and a contemporary of Ezekiel’s, therefore we can safely recognize Noah and Job were actual people and therefore their accounts not just stories.
