Let us take especial care, sisters, to pray to Him for them, and not be negligent. To pray for those who are in mortal sin is the best kind of almsgiving -- a much better thing than it would be to loose a Christian whom we saw with his hands tied behind him, bound with a stout chain, made fast to a post and dying of hunger, not for lack of food, since he has beside him the most delicious things to eat, but because he cannot take them and put them into his mouth although he is weary to death and actually knows that he is on the point of dying, and not merely a death of the body, but one which is eternal. Would it not be extremely cruel to stand looking at such a man and not give him this food to eat? And supposing you could loose his chains by means of your prayers? You see now what I mean. For the love of God, I beg you always to remember such souls when you pray.214
