Job 36:11

If they obey and serve him - That is, if, as the result of their afflictions, they repent of their sins, seek his mercy, and serve him in time to come, they shall be prospered still. The design of affliction, Elihu says, is, not to cut them off, but to bring them to repentance. This sentiment he had advanced and illustrated before at greater length; see the notes at Job 33:23. The object of all this is, doubtless, to assure Job that he should not regard his calamities either as proof that he had never understood religion - as his friends maintained; or that God was severe, and did not regard those that loved and obeyed him - as Job had seemed to suppose; but that there was something in his life and conduct which made discipline necessary, and that if he would repcnt of that, he would find returning prosperity, and end his days in happiness and peace.
