5 THE PRACTICAL CONCLUSION
How is this to be done? Now, please remember how we acquired the old, ordinary kind of life. We derived it from others, from our father and mother and all our ancestors, without our consentand by a very curious process, involving pleasure, pain, and danger. A process you would never have guessed. Most of us spend a good many years in childhood trying to guess it: and some children, when they are first told, do not believe itand I am not sure that I blame them, for it is very odd. Now the God who arranged that process is the same God who arranges how the new kind of lifethe Christ-lifeis to be spread. We must be prepared for it being odd too. He did not consult us when He invented sex: He has not consulted us either when He invented this.
There are three things that spread the Christ-life to us: baptism, belief, and that mysterious action which different Christians call by different namesHoly Communion, the Mass, the Lords Supper. At least, those are the three ordinary methods. I am not saying there may not be special cases where it is spread without one or more of these. I have not time to go into special cases, and I do not know enough. If you are trying in a few minutes to tell a man how to get to Edinburgh you will tell him the trains: he can, it is true, get there by boat or by a plane, but you will hardly bring that in. And I am not saying anything about which of these three things is the most essential. My Methodist friend would like me to say more about belief and less (in proportion) about the other two. But I am not going into that. Anyone who professes to teach you Christian doctrine will, in fact, tell you to use all three, and that is enough for our present purpose.
I cannot myself see why these things should be the conductors of the new kind of life. But then, if one did not happen to know, I should never have seen any connection between a particular physical pleasure and the appearance of a new human being in the world. We have to take reality as it comes to us: there is no good jabbering about what it ought to be like or what we should have expected it to be like. But though I cannot see why it should be so, I can tell you why I believe it is so. I have explained why I have to believe that Jesus was (and is) God. And it seems plain as a matter of history that He taught His followers that the new life was communicated in this way. In other words, I believe it on His authority. Do not be scared by the word authority. Believing things on authority only means believing them because you have been told them by someone you think trustworthy. Ninety-nine per cent of the things you believe are believed on authority. I believe there is such a place as New York. I have not seen it myself. I could not prove by abstract reasoning that there must be such a place. I believe it because reliable
people have told me so. The ordinary man believes in the Solar System, atoms, evolution, and the circulation of the blood on authoritybecause the scientists say so. Every historical statement in the world is believed on authority. None of us has seen the Norman Conquest or the defeat of the Armada. None of us could prove them by pure logic as you prove a thing in mathematics. We believe them simply because people who did see them have left writings that tell us about them: in fact, on authority. A man who jibbed at authority in other things as some people do in religion would have to be content to know nothing all his life.
Do not think I am setting up baptism and belief and the Holy Communion as things that will do instead of your own attempts to copy Christ. Your natural life is derived from your parents; that does not mean it will stay there if you do nothing about it. You can lose it by neglect, or you can drive it away by committing suicide. You have to feed it and look after it: but always remember you are not making it, you are only keeping up a life you got from someone else. In the same way a Christian can lose the Christ-life which has been put into him, and he has to make efforts to keep it. But even the best Christian that ever lived is not acting on his own steamhe is only nourishing or protecting a life he could never have acquired by his own efforts. And that has practical consequences. As long as the natural life is in your body, it will do a lot towards repairing that body. Cut it, and up to a point it will heal, as a dead body would not. A live body is not one that never gets hurt, but one that can to some extent repair itself. In the same way a Christian is not a man who never goes wrong, but a man who is enabled to repent and pick himself up and begin over again after each stumblebecause the Christ-life is inside him, repairing him all the time, enabling him to repeat (in some degree) the kind of voluntary death which Christ Himself carried out.
That is why the Christian is in a different position from other people who are trying to be good. They hope, by being good, to please God if there is one; orif they think there is notat least they hope to deserve approval from good men. But the Christian thinks any good he does comes from the Christ-life inside him. He does not think God will love us because we are good, but that God will make us good because He loves us; just as the roof of a greenhouse does not attract the sun because it is bright, but becomes bright because the sun shines on it.
