Job's afflictions began from the malice of Satan, by the Lord's permission, for wise and holy purposes. There is an evil spirit, the enemy of God, and of all righteousness, who is continually seeking to distress, to lead astray, and, if possible, to destroy those who love God. How far his influence may extend, we cannot say; but probably much unsteadiness and unhappiness in Christians may be ascribed to him. While we are on this earth we are within his reach. Hence it concerns us to be sober and vigilant, Revelation 20:1. He has no power to lead men to sin, but what they give him themselves; nor any power to afflict men, but what is given him from above. All this is here described to us after the manner of men. The Scripture speaks thus to teach us that God directs the affairs of the world.
