I have been thinking very hard about the question in your last letter. If, as I have clearly shown, all selves are by their very nature in competition, and therefore the Enemy’s idea of Love is a contradiction in terms, what becomes of my reiterated warning that He really loves the human vermin and really desires their freedom and continued existence? I hope, my dear boy, you have not shown my letters to anyone. Not that it matters of course. Anyone would see that the appearance of heresy into which I have fallen is purely accidental. By the way, I hope you understood, too, that some apparently uncomplimentary references to Slubgob were purely jocular. I really have the highest respect for him. And, of course, some things I said about not shielding you from the authorities were not seriously meant. You can trust me to look after your interests. But do keep everything under lock and key.
The truth is I slipped by mere carelessness into saying that the Enemy really loves the humans. That, of course, is an impossibility. He is one being, they are distinct from Him. Their good cannot be His. All His talk about Love must be a disguise for something else—He must have some real motive for creating them and taking so much trouble about them. The reason one comes to talk as if He really had this impossible Love is our utter failure to out that real motive. What does He stand to make out of them? That is the insoluble question. I do not see that it can do any harm to tell you that this very problem was a chief cause of Our Father’s quarrel with the Enemy. When the creation of man was first mooted and when, even at that stage, the Enemy freely confessed that he foresaw a certain episode about a cross, Our Father very naturally sought an interview and asked for an explanation. The Enemy gave no reply except to produce the cock-and-bull story about disinterested love which He has been circulating ever since. This Our Father naturally could not accept. He implored the Enemy to lay His cards on the table, and gave Him every opportunity. He admitted that he felt a real anxiety to know the secret; the Enemy replied “I wish with all my heart that you did”. It was, I imagine, at this stage in the interview that Our Father’s disgust at such an unprovoked lack of confidence caused him to remove himself an infinite distance from the Presence with a suddenness which has given rise to the ridiculous enemy story that he was forcibly thrown out of Heaven. Since then, we have begun to see why our Oppressor was so secretive. His throne depends on the secret. Members of His faction have frequently admitted that if ever we came to understand what He means by Love, the war would be over and we should re-enter Heaven. And there lies the great task. We know that He cannot really love: nobody can: it doesn’t make sense. If we could only find out what He is really up to! Hypothesis after hypothesis has been tried, and still we can’t find out. Yet we must never lose hope; more and more complicated theories, fuller and fuller collections of data, richer rewards for researchers who make progress, more and more terrible punishments for those who fail—all this, pursued and accelerated to the very end of time, cannot, surely, fail to succeed.
CS Lewis, The Screwtape Letters
I have read an endless, perhaps too many, books in this life. Most have been forgettable, at least forgotten by me almost entirely a year or two after I read them. Perhaps a hundred have stayed with me, marking themselves on my brain and soul. Near the top of that last, the pinnacle being occupied by the book of books, The Bible, is The Screwtape Letters. I read it as a sophomore in college and many times since then. It brought to my attention spiritual realities that had largely eluded me up to that time. If I escape Hell it will be due primarily to unmerited grace from God in the sacraments, the love of so many people that God in His Mercy has placed in my path through this Vale of Tears, the Bible and this book written by a former atheist. God has a grand sense of humor and endless love, and Satan lacks all humor and all love, something that Lewis knew and use so effectively in his book.

Thanks, Don, for posting this reminder of the evil one within us.
Satan never sleeps Bob, but neither does God.
