Is wisdom important during times of suffering?

After defending his integrity from his 3 friends, Job spent the entire chapter 28 on "Where wisdom is found?". Why?

So far, the arguments from Job's friends had been:

1. God is righteous and fair.
2. God rewards those who are good and punishes those who are evil.
3. Job's suffering is God's punishment - therefore Job has unconfessed sins.
4. Even though Job denied (or was unaware of) any unconfessed sins he could never be good enough because God's righteousness is the standard by which human's righteousness is measured.
5. If Job would just confess his sins God will bless him again.

This is naturally the kind of linear thinking we are familiar with and have lived by all our lives. Job was genuinely confused. He had lived his life more or less following these same principles also. In fact just to be sure, he made sure even his children stayed pure:
His (Job's) sons used to hold feasts in their homes on their birthdays, and they would invite their three sisters to eat and drink with them. When a period of feasting had run its course, Job would make arrangements for them to be purified. Early in the morning he would sacrifice a burnt offering for each of them, thinking, “Perhaps my children have sinned and cursed God in their hearts.” This was Job’s regular custom. (Jobs 1:4-5)

So why all of a sudden a loving God who had been so close to him would send him such calamities?
“How I long for the months gone by,
    for the days when God watched over me,
when his lamp shone on my head
    and by his light I walked through darkness!
Oh, for the days when I was in my prime,
    when God’s intimate friendship blessed my house,
when the Almighty was still with me
    and my children were around me,
when my path was drenched with cream
    and the rock poured out for me streams of olive oil. (Job 29:2-6)

Wisdom is needed. And where do you find such wisdom?

• Like precious stones and minerals are only found in deep mines and buried stones, we need to dig deep to find wisdom. (Job 28:1-11)
• The price of wisdom is beyond any monetary value. (Job 28:12-19)
• Only the powerful and creative God knows where to find it. (Job 28:20-27)
• So we can begin to find wisdom by this:
      And he said to the human race, “The fear of the Lord—that is wisdom,
      and to shun evil is understanding.” (Job 28:28)

"The fear of the Lord is the beginning of wisdom" - is a major theme in the bible. It is found in other places: Psalm 111:10, Proverbs 1:7, and Proverbs 9:10.

What does it mean to fear God? This article from Christianity Today is a very good read on this topic - good food for thought for this week.

Jesus tells us: "Don't be afraid of those who want to kill your body; they cannot touch your soul. Fear only God, who can destroy both soul and body in hell" (Matthew 10:28)
