Job’s friends have theories about God. They think they understand God. But these theories can’t explain the reality of Job’s situation. These theories attempt to place God in a box, to reduce God to someone they can control. But in Job 12, it is clear that God cannot be managed.
“To God belong wisdom and power; counsel and understanding are his. What he tears down cannot be rebuilt; the man he imprisons cannot be released. If he holds back the waters, there is drought; if he lets them loose, they devastate the land. To him belong strength and victory; both deceived and deceiver are his. He leads counselors away stripped and makes fools of judges. He takes off the shackles put on by kings and ties a loincloth around their waist. He leads priests away stripped and overthrows men long established. He silences the lips of trusted advisers and takes away the discernment of elders.”
His friends just do not seem to understand the character of God.
