For example, if a sick man is disposed to bear his illness with a good heart and does so, the enemy knowing that he will thus become well grounded in the virtue of patience, attempts to disrupt this good disposition. For this purpose, he begins to remind him of the many good deeds he could have performed had his position been different, and tries to convince him that, had he been in good health, he would have achieved much in the service of God, bringing much profit to himself and others. He would have been able to go to church, to talk to people, to rend and to write for the instruction of his brethren, and so on. If he notices that such thoughts are accepted, the enemy introduces them into the man’s mind more and more often, multiplies and embellishes them, makes them enter the feelings and incites desires and impulses to such actions by depicting how successful these or other works would have been, and by evoking regret that the man is tied hand and foot by his illness. Little by little, after frequent repetition of such thoughts and inner movements in the soul, regret is gradually transformed into discontent and vexation. Thus the former good-hearted patience is upset and, instead of a medicine sent by God and a field for practising the virtue of patience, the illness presents itself as something hostile to the work of salvation. Thus the desire to be free of it becomes ungovernable, though still with a view to freedom to perform good deeds and to please God in every way. Having led a man thus far, the enemy robs his heart and mind of the good purpose, for which he desires to get well, and leaves only the desire of health for the sake of health, forcing him to look irritably at his illness, not as an obstacle to good but as an evil in itself. As a result impatience, not tempered by good thoughts, takes the upper hand and passes to complainings, thus depriving the sick man of the peace he enjoyed through good-hearted patience. But the enemy rejoices that he has managed to upset him. In exactly the same way, the enemy upsets a poor man who bears his lot with patience, depicting to him the good deeds he could do if he had a fortune.
