To try the just, God employs the malice of demons and the perversity of sinners.  Job lost his children and his possessions.  He fell from opulence to misery.  And then he said: “The Lord gave and the Lord hath taken away.  As it hath pleased the Lord, so is it done?  Blessed be the name of the Lord.”  As St Augustine remarks on this, “Job did not say: The Lord gave and the devil hath taken away.  Everything has happened, not according to the devil’s will, but according to the will of God.  Refer, then, to Him all the evils that happen to you, for the devil himself can do you no hurt without His permission.  –Abbot Vitalis Lehodey ‘Holy Abandonment’
