Where is God's Focus in The Book of Job?

The Book of Job is one of the most hypothesized books in the Bible. There are so many opinions about things contained in the book that it is mind-boggling!  As I look into some of the sections of the book and take my time, it is fairly evident that most people get it wrong one way or another. Don't get me wrong, I don't have all the right answers, but I can see all the contradictions of opinions that pile up with each and every theory.

God actually spoke in the beginning and end of this book.  In the beginning, he praised Job for his righteousness. In the end, God praised Job again. In between, we read a lot of human dialogue page after page, where there is a lot of mention of sin and blame from Job's friends, which got worse and worse before God stepped in.

When God spoke to Job directly  ,he set the tone with:

2 Who is this that darkeneth (dims the light) counsel (advice) by words without knowledge (discernment, thinking)? 3 Gird up now thy loins like a man; for I will demand (ask) of thee, and answer thou me. Job 38:2-3

These two verses are sliced and diced over and over by people who study  the book of Job.

I looked up what it means 'to gird up the loins'. The phrase is used several times in the Bible. Some historians describe this as pulling up the tunic and tucking it in to be ready to move. Job was not going anywhere physically, but spiritually he was moving forward. In  Ephesians 6 it says:

14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;15 And your feet shod with the preparation of the gospel of peace;

After the discourse in Job 38:1-3, God asked Job question after question!  God asks questions throughout the Bible and this is the longest list to any individual. The questions are thought-provoking! The questions allowed and encouraged Job to think! (Check out Genesis 4:6, Job 1:7, Acts 9:5, Romans 8:31-39, or the first question in the Bible 'Where art thou ?' in Genesis 3:9). The questions didn't box him in, accuse or blame him; they freed Job, because he wanted to be freed:

5 I have heard of thee by the hearing of the ear: but now mine eye seeth thee. Job 42:5
