When he had eluded the flood of temptation many times in this way he grew troubled and wondered whether the grace which he had refused to lose was not being filched from him little by little. The clear certitude of his own immunity grew dim and to it succeeded a vague fear that his soul had really fallen unawares. It was with difficulty that he won back his old consciousness of his state of grace by telling himself that he had prayed to God at every temptation and that the grace which he had prayed for must have been given to him inasmuch as God was obliged to give it. The very frequency and violence of temptations showed him at last the truth of what he had heard about the trials of the saints. Frequent and violent temptations were a proof that the citadel of the soul had not fallen and that the devil raged to make it fall.
