The great thing is to prevent his doing anything. As long as he does not convert it into action, it does not matter how much he thinks about this new repentance. Let the little brute wallow in it. Let him, if he has any bent that way, write a book about it; that is often an excellent way of sterilizing the seeds which the Enemy plants in a human soul. Let him do anything but act. No amount of piety in his imagination and affections will harm us if we can keep it out of his will. As one of the humans has said, active habits are strengthened by repetition but passive ones are weakened. The more often he feels without acting, the less he will be able ever to act, and, in the long run, the less he will be able to feel,
