A C.S. Lewis Scewtape Letters' Quote on Sin, Distraction and Spiritual Warfare for Advent

MY DEAR WORMWOOD,

You seem to be doing very little good at present. The use of his “love” to distract his mind from the Enemy is, of course, obvious, but you reveal what poor use you are making of it when you say that the whole question of distraction and the wandering mind has now become one of the chief subjects of his prayers. That means you have largely failed. When this, or any other distraction, crosses his mind you ought to encourage him to thrust it away by sheer will power and to try to continue the normal prayer as if nothing had
happened; once he accepts the distraction as his present problem and lays that before the Enemy and makes it the main theme of his prayers and his endeavours, then, so far from doing good, you have done harm. Anything, even a sin, which has the total effect of moving him close up to the Enemy, makes against us in the long run….

Your affectionate uncle
