Men seek an explanation of suffering in cause and effect. They look backward for a connection between prior sin and present suffering. The Bible looks forward in hope and seeks explanations, not so much in origins as in goals. The purpose of suffering is seen, not in its cause, but in its results. The man in John 9 was born blind so that the works of God could be displayed in him.
