Job has just lost everything--his wealth, his health, and all 10 of his children!
His friends come to mourn with him; then after a week, they try to get him to see the light as to why all this has happened to him.
Bildad's opening counsel includes the following bit of helpful perspective: "If your sons have sinned against Him, He has cast them away for their transgression." (Job 8:4, NKJV)
When I get to chapter 9, I'm sure I will read Job saying something like, "Ahh, thank you, Bildad. I was wondering why they all died. But, of course, they were such hideous scoundrels. Thank you, friend. I feel much better."
[Side Note: What's interesting about the friends' counsel is that sometimes they get it right, but they misapply what they get right to Job. Indeed, some of their counsel reads as if it were ripped right from the Psalms. But even the Psalms have to be applied correctly. (Example: Exactly what does Psalm 91:9-10 mean?)]
A few verses later, Bildad is more prophetic than he realizes: "If you were pure and upright, surely now He would awake for you, and prosper your rightful dwelling place. Though your beginning was small, yet your latter end would increase abundantly." (Job 8:6-7 NKJV, emphasis added)
Comparing Job 42 with Job 1, Yahweh doubled all his possessions, and he once again had 7 sons and 3 daughters. On Bildad's take of things, then, Job was "pure and upright," but the horrible trial happened anyway!
