Job was a really good man. So, when he suffered, Job concluded that God wasn't just. His friends argued that Job must not be good because God is surely just. How many still come to one of those conclusions in the midst of suffering– God isn't fair or this must be my punishment for sin. By the end of the book, God explains that suffering is more complicated than they think, and the right response for us is to trust Him, who is sovereign through it all.
