If the first and lowest operation of pain shatters the illusion that all is well, the second shatters the illusion that what we have, whether good or bad in itself, is our own and enough for us. Everyone has noticed how hard it is to turn our thoughts to God when everything is going well with us. We ‘have all we want’ is a terrible saying when ‘all’ does not include God. We find God an interruption. As St Augustine says somewhere, ‘God wants to give us something, but cannot, because our hands are full—there’s nowhere for Him to put it.’ Or as a friend of mine said, ‘We regard God as an airman regards his parachute; it’s there for emergencies but he hopes he’ll never have to use it.’ Now God, who has made us, knows what we are and that our happiness lies in Him. Yet we will not seek it in Him as long as he leaves us any other resort where it can even plausibly be looked for. While what we call ‘our own life’ remains agreeable we will not surrender it to Him. What then can God do in our interests but make ‘our own life’ less agreeable to us, and take away the plausible source of false happiness?

[The demon Screwtape writes:] The humans live in time but our Enemy destines them to eternity. He therefore, I believe, wants them to attend chiefly to two things, to eternity itself, and to that point of time which they call the Present. For the Present is the point at which time touches eternity. Of the present moment, and of it only, humans have an experience analogous to the experience which our Enemy has of reality as a whole; in it alone freedom and actuality are offered them. He would therefore have them continually concerned either with eternity (which means being concerned with Him) or with the Present—either meditating on their eternal union with, or separation from, Himself, or else obeying the present voice of conscience, bearing the present cross, receiving the present grace, giving thanks for the present pleasure.

Our business is to get them away from the eternal, and from the Present. With this in view, we sometimes tempt a human (say a widow or a scholar) to live in the Past. But this is of limited value, for they have some real knowledge of the past and it has a determinate nature and, to that extent, resembles eternity. It is far better to make them live in the Future. Biological necessity makes all their passions point in that direction already, so that thought about the Future inflames hope and fear. Also, it is unknown to them, so that in making them think about it we make them think of unrealities. In a word, the Future is, of all things, the thing least like eternity. It is the most completely temporal part of time—for the Past is frozen and no longer flows, and the Present is all lit up with eternal rays.

The rule for all of us is perfectly simple. Do not waste time bothering whether you ‘love’ your neighbour; act as if you did. As soon as we do this we find one of the great secrets. When you are behaving as if you loved someone, you will presently come to love him. If you injure someone you dislike, you will find yourself disliking him more. If you do him a good turn, you will find yourself disliking him less. There is, indeed, one exception. If you do him a good turn, not to please God and obey the law of charity, but to show him what a fine forgiving chap you are, and to put him in your debt, and then sit down to wait for his ‘gratitude’, you will probably be disappointed. (People are not fools: they have a very quick eye for anything like showing off, or patronage.) But whenever we do good to another self, just because it is a self, made (like us) by God, and desiring its own happiness as we desire ours, we shall have learned to love it a little more or, at least, to dislike it less.

If the old fairy-tale ending ‘They lived happily ever after’ is taken to mean ‘They felt for the next fifty years exactly as they felt the day before they were married’, then it says what probably never was nor ever would be true, and would be highly undesirable if it were. Who could bear to live in that excitement for even five years? What would become of your work, your appetite, your sleep, your friendships? But, of course, ceasing to be ‘in love’ need not mean ceasing to love. Love in this second sense—love as distinct from ‘being in love’—is not merely a feeling. It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by (in Christian marriages) the grace which both partners ask, and receive, from God. They can have this love for each other even at those moments when they do not like each other; as you love yourself even when you do not like yourself. They can retain this love even when each would easily, if they allowed themselves, be ‘in love’ with someone else. ‘Being in love’ first moved them to promise fidelity: this quieter love enables them to keep the promise. It is on this love that the engine of marriage is run: being in love was the explosion that started it.

The idea that ‘being in love’ is the only reason for remaining married really leaves no room for marriage as a contract or promise at all. If love is the whole thing, then the promise can add nothing; and if it adds nothing, then it should not be made. The curious thing is that lovers themselves, while they remain really in love, know this better than those who talk about love. As Chesterton pointed out, those who are in love have a natural inclination to bind themselves by promises. Love songs all over the world are full of vows of eternal constancy. The Christian law is not forcing upon the passion of love something which is foreign to that passion’s own nature: it is demanding that lovers should take seriously something which their passion of itself impels them to do.

And, of course, the promise, made when I am in love and because I am in love, to be true to the beloved as long as I live, commits me to being true even if I cease to be in love. A promise must be about things that I can do, about actions: no one can promise to go on feeling in a certain way. He might as well promise never to have a headache or always to feel hungry.

When it comes to a question of our forgiving other people, it is partly the same and partly different. It is the same because, here also, forgiving does not mean excusing. Many people seem to think it does. They think that if you ask them to forgive someone who has cheated or bullied them you are trying to make out that there was really no cheating or no bullying. But if that were so, there would be nothing to forgive. They keep on replying, “But I tell you the man broke a most solemn promise.” Exactly: that is precisely what you have to forgive. (This doesn’t mean that you must necessarily believe his next promise. It does mean that you must make every effort to kill every taste of resentment in your own heart—every wish to humiliate or hurt him or to pay him out.) The difference between this situation and the one in which you are asking God’s forgiveness is this. In our own case we accept excuses too easily; in other people’s we do not accept them easily enough.

TO MARY WILLIS SHELBURNE: On rejoicing over answered prayer; and on our prayers being God’s prayers.

6 November 1953

Oh I am glad, I am glad. And here’s a thing worth recording. Of course I have been praying for you daily, as always, but latterly have found myself doing so with much more concern and especially about 2 nights ago, with such a strong feeling how very nice it would be, if God willed, to get a letter from you with good news. And then, as if by magic (indeed it is the whitest magic in the world) the letter comes to-day. Not (lest I should indulge in folly) that your relief had not in fact occurred before my prayer, but as if, in tenderness for my puny faith, God moved me to pray with especial earnestness just be- fore He was going to give me the thing. How true that our prayers are really His prayers: He speaks to Himself through us.

I am also most moved at hearing how you were supported through the period of anxiety. For one is sometimes tempted to think that if He wanted us to be as un-anxious as the lilies of the field He really might have given us a constitution more like theirs! But then when the need comes He carries out in us His otherwise impossible instructions. In fact He always has to do all the things—all the prayers, all the virtues. No new doctrine, but newly come home to me.

On the lord’s prayer

We believe that God forgives us our sins; but also that He will not do so unless we forgive other people their sins against us. There is no doubt about the second part of this statement. It is in the Lord’s Prayer; it was emphatically stated by our Lord. If you don’t forgive, you will not be forgiven. No part of His teaching is clearer, and there are no exceptions to it. He doesn’t say that we are to forgive other people’s sins provided they are not too frightful, or provided there are extenuating circumstances, or anything of that sort. We are to forgive them all, however spiteful, however mean, however often they are repeated. If we don’t, we shall be forgiven none of our own.
