NOTES for Job 8:3-4
In his self-confidence, Bildad surpasses everyone who answers Job, and categorically, without having the facts but guided by general considerations, he declares that Job's sons rightly suffered for their sins. Bildad is right when he says that God is just, but it is strange that he does not take into account that after the fall the world lies in evil, and therefore much of what happens in the world does not correspond to the Creator's intent. For some reason, both Bildad and moralists like him forget that there is much evil in the world regardless of whether disasters rightly fall on people, and we have no right to call every calamity a punishment for sins.
Bildad's hope in God is completely right, but it is joined to a judgment he has taken upon himself willfully. In essence, Bildad puts himself in God's place and tries to decide on His behalf, without having the slightest grounds for doing so.
