27 Nothing of this sort did Job utter, no nor think, because he knew that God was dispensing all things for good. That you may learn, moreover, that he gave a heavier blow to the devil after this, when, being stripped of all things, he gave thanks, than when, being in possession of them, he gave alms; observe, that when he was in possession, the devil could utter a certain suspicion, and however false, he yet could utter it: “Does Job serve you for nought?” But when he had taken all, and stripped him of everything, and the man yet retained the same good will towards God, from that time his shameless mouth was stopped, and had nothing further to allege. For the just man was more illustrious than in his former state. For to bear nobly and thankfully the privation of all things, is a far greater thing than it was to give alms while living in affluence; and it has been accordingly demonstrated in the case of this just man. Before, there was much benignity to his fellow-servants; now, there was exceeding love shown towards the Lord!
