"'What is mankind that you make so much of them, that you give them so much attention, that you examine them every morning and test them every moment? Will you never look away from me, or let me alone even for an instant?'" NIV translation
We continue to watch as Job's integrity (blamelessness in God's eyes) evaporates. In the previous passage, he accused God of wrongdoing and now he basically accuses God of being too critical in His examination of mankind. He describes God as if he were a slave master just waiting for men to "mess up" so that He can beat them down.
This is a horrible misconception about the nature of God and it is still widespread in our world today. Why does God watch over His children and even discipline then in some cases? The simple fact of the matter is that God does so because of His love for us and the fact that he knows what is best for us.
Nevertheless, God is not just waiting for us to mess up so that He can beat us down. On the contrary. He accepts us where we are and gently corrects us as we grow and mature in our faith.
"'If I have sinned, what have I done to you, you who see everything we do? Why have you made me your target? Have I become a burden to you? Why do you not pardon my offenses and forgive my sins? For I will soon lie down in the dust; you will search for me, but I will be no more.'" NIV translation
We see the fact that Job's integrity is gone as we see evidence of self-righteousness in his words: "If I have sinned". Job offers up several questions basically continuing to accuse God of wrongdoing. We remember that this story began with Job presenting offerings to God just in case his children had sinned but, now, he does not see this sin of self-righteousness on his part.
