The classic Weight of Glory by C.S. Lewis, the most important Christian writer of the 20th century, contains nine sermons delivered by Lewis during World War Two. The nine addresses in Weight of Glory offer guidance, inspiration, and a compassionate apologetic for the Christian faith during a time of great doubt.
The Weight of Glory
If you asked twenty good men today what they thought the highest of the virtues, nineteen of them would reply, Unselfishness. But if you had asked almost any of the great Christians of old, he would have replied, Love. You see what has happened? A negative term has been substituted for a positive, and this is of more than philological importance. The negative idea of Unselfishness carries with it the suggestion not primarily of securing good things for others, but of going without them ourselves, as if our abstinence and not their happiness was the important point. I do not think this is the Christian virtue of Love. The New Testament has lots to say about self-denial, but not about self-denial as an end in itself. We are told to deny ourselves and to take up our crosses in order that we may follow Christ; and nearly every description of what we shall ultimately find if we do so contains an appeal to desire. If there lurks in most modern minds the notion that to desire our own good and earnestly to hope for the enjoyment of it is a bad thing, I submit that this notion has crept in from Kant and the Stoics and is no part of the Christian faith. Indeed, if we consider the unblushing promises of reward and the staggering nature of the rewards promised in the Gospels, it would seem that Our Lord finds our desires not too strong, but too weak. We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased.
We must not be troubled by unbelievers when they say that this promise of reward makes the Christian life a mercenary affair. There are different kinds of rewards. There is the reward which has no natural connection with the things you do to earn it and is quite foreign to the desires that ought to accompany those things. Money is not the natural reward of love; that is why we call a man mercenary if he marries a woman for the sake of her money. But marriage is the proper reward for a real lover, and he is not mercenary for desiring it. A general who fights well in order to get a peerage is mercenary; a general who fights for victory is not, victory being the proper reward of battle as marriage is the proper reward of love. The proper rewards are not simply tacked on to the activity for which they are given, but are the activity itself in consummation. There is also a third case, which is more complicated. An enjoyment of Greek poetry is certainly a proper, and not a mercenary, reward for learning Greek; but only those who have reached the stage of enjoying Greek poetry can tell from their own experience that this is so. The schoolboy beginning Greek grammar cannot look forward to his adult enjoyment of Sophocles as a lover looks forward to marriage or a general to victory. He has to begin by working for marks, or to escape punishment, or to please his parents, or, at best, in the hope of a future good which he cannot at present imagine or desire. His position, therefore, bears a certain resemblance to that of the mercenary; the reward he is going to get will, in actual fact, be a natural or proper reward, but he will not know that till he has got it. Of course, he gets it gradually; enjoyment creeps in upon the mere drudgery, and nobody could point to a day or an hour when the one ceased and the other began. But it is just insofar as he approaches the reward that he becomes able to desire it for its own sake; indeed, the power of so desiring it is itself a preliminary reward.
The Christian, in relation to heaven, is in much the same position as this schoolboy. Those who have attained everlasting life in the vision of God doubtless know very well that it is no mere bribe, but the very consummation of their earthly discipleship; but we who have not yet attained it cannot know this in the same way, and cannot even begin to know it at all except by continuing to obey and finding the first reward of our obedience in our increasing power to desire the ultimate reward. Just in proportion as the desire grows, our fear lest it should be a mercenary desire will die away and finally be recognised as an absurdity. But probably this will not, for most of us, happen in a day; poetry replaces grammar, gospel replaces law, longing transforms obedience, as gradually as the tide lifts a grounded ship.
But there is one other important similarity between the schoolboy and ourselves. If he is an imaginative boy, he will, quite probably, be revelling in the English poets and romancers suitable to his age some time before he begins to suspect that Greek grammar is going to lead him to more and more enjoyments of this same sort. He may even be neglecting his Greek to read Shelley and Swinburne in secret. In other words, the desire which Greek is really going to gratify already exists in him and is attached to objects which seem to him quite unconnected with Xenophon and the verbs in [Greek]. Now, if we are made for heaven, the desire for our proper place will be already in us, but not yet attached to the true object, and will even appear as the rival of that object. And this, I think, is just what we find. No doubt there is one point in which my analogy of the schoolboy breaks down.
