St. Therese of Lisieux
“Should the devil draw my attention to the faults of any one of them when I am seeking to increase this love in my heart, I call to mind at once her virtues and her good intentions. I tell myself that though I may have seen her fall once, there are probably a great many other occasions on which she has won victories which, in her humility, she has kept to herself. What may appear to me to be a fault may even be an act of virtue because of her intention, and as I have experienced this for myself, I have little difficulty in persuading myself that this is indeed the case.“
