“I have heard of thee by the hearing of the ear: but now mine eye seeth thee.”
It is possible that the book of Job was the first book of the Bible to be written. Now, there are godly Bible expositors who will agree with what I have just said and others who would strongly disagree. But it seems likely to me that it is very old, as it mentions snow and ice in areas where snow and ice do not occur today. This suggests that the events of the book of Job took place during the Ice Age that many creationists believe must have occurred after the Flood. It is possible – and this is speculative and definitely not to be taken as firm fact – that Job is the same person as a man named Jobab in Genesis 10:28, who was the son of Joktan and the great great great great grandson of Noah.
If the events of Job are really early post-Flood, then this would underscore the importance of the statements made in the book about creation. For example, the book frequently refers to stars and to animals. From chapter 38 onward, God describes a large variety of the things that He made and shows that it is in this context that everything that has happened to Job should be interpreted. Job is reminded that, while his suffering has been great, God has a higher purpose in mind, and His care for us is far greater than our mistaken self-centered impression can take in.
