And let me make it quite clear that when Christians say the Christ-life is in them, they do not mean simply something mental or moral. When they speak of being in Christ or of Christ being in them, this is not simply a way of saying that they are thinking about Christ or copying Him. They mean that Christ is actually operating through them; that the whole mass of Christians are the physical organism through which Christ actsthat we are His fingers and muscles, the cells of His body. And perhaps that explains one or two things. It explains why this new life is spread not only by purely mental acts like belief, but by bodily acts like baptism and Holy Communion. It is not merely the spreading of an idea; it is more like evolutiona biological or superbiological fact. There is no good trying to be more spiritual than God. God never meant man to be a purely spiritual creature. That is why He uses material things like bread and wine to put the new life into us. We may think this rather crude and unspiritual. God does not: He invented eating. He likes matter. He invented it.
Here is another thing that used to puzzle me. Is it not frightfully unfair that this new life should be confined to people who have heard of Christ and been able to believe in Him? But the truth is God has not told us what His arrangements about the other people are. We do know that no man can be saved except through Christ; we do not know that only those who know Him can be saved through Him. But in the meantime, if you are worried about the people outside, the most unreasonable thing you can do is to remain outside yourself. Christians are Christs body, the organism through which He works. Every addition to that body enables Him to do more. If you want to help those outside you must add your own little cell to the body of Christ who alone can help them. Cutting off a mans fingers would be an odd way of getting him to do more work.
Another possible objection is this. Why is God landing in this enemy-occupied world in disguise and starting a sort of secret society to undermine the devil? Why is He not landing in force, invading it? Is it that He is not strong enough? Well, Christians think He is going to land in force; we do not know when. But we can guess why He is delaying. He wants to give us the chance of joining His side freely.
I do not suppose you and I would have thought much of a Frenchman who waited till the Allies were marching into Germany and then announced he was on our side. God will invade. But I wonder whether people who ask God to interfere openly and directly in our world quite realise what it will be like when He does. When that happens, it is the end of the world. When the author walks on to the stage the play is over. God is going to invade, all right: but what is the good of saying you are on His side then, when you see the whole natural universe melting away like a dream and something elsesomething it never entered your head to conceivecomes crashing in; something so beautiful to some of us and so terrible to others that none of us will have any choice left? For this time it will be God without disguise; something so overwhelming that it will strike either irresistible love or irresistible horror into every creature. It will be too late then to choose your side. There is no use saying you choose to lie down when it has become impossible to stand up. That will not be the time for choosing: it will be the time when we discover which side we really have chosen, whether we realised it before or not. Now, today, this moment, is our chance to choose the right side. God is holding back to give us that chance. It will not last for ever. We must take it or leave it.
1 THE THREE PARTS OF MORALITY
Some people prefer to talk about moral ideals rather than moral rules and about moral idealism rather than moral obedience. Now it is, of course, quite true that moral perfection is an ideal in the sense that we cannot achieve it. In that sense every kind of perfection is, for us humans, an ideal; we cannot succeed in being perfect car drivers or perfect tennis players or in drawing perfectly straight lines. But there is another sense in which it is very misleading to call moral perfection an ideal. When a man says that a certain woman, or house, or ship, or garden is his ideal he does not mean (unless he is rather a fool) that everyone else ought to have the same ideal. In such matters we are entitled to have different tastes and, therefore, different ideals. But it is dangerous to describe a man who tries very hard to keep the moral law as a man of high ideals, because this might lead you to think that moral perfection was a private taste of his own and that the rest of us were not called on to share it. This would be a disastrous mistake. Perfect behaviour may be as unattainable as perfect gear-changing when we drive; but it is a necessary ideal prescribed for all men by the very nature of the human machine just as perfect gear-changing is an ideal prescribed for all drivers by the very nature of cars. And it would be even more dangerous to think of oneself as a person of high ideals because one is trying to tell no lies at all (instead of only a few lies) or never to commit adultery (instead of committing it only seldom) or not to be a bully (instead of being only a moderate bully). It might lead you to become a prig and to think you were rather a special person who deserved to be congratulated on his idealism. In reality you might just as well expect to be congratulated because, whenever you do a sum, you try to get it quite right. To be sure, perfect arithmetic is an ideal; you will certainly make some mistakes in some calculations. But there is nothing very fine about trying to be quite accurate at each step
