This man Eliphaz continues with his own thoughts which he had drawn from his own experience. The wiser these sound, the more wicked they are, because they fool people. What he is saying here is that everything which happens to us is caused by something which we have done. So in verse 17 he says that God is correcting people. By this he was suggesting that Job needed to correct his life. He tells him to cheer up, in the end everything would come out well. Isn’t that what the world says today?
