Time Reconsidered
I should like to deal with a difficulty that some people find about the whole idea of prayer. A man put it to me by saying ‘I can believe in God all right, but what I cannot swallow is the idea of Him attending to several hundred million human beings who are all addressing Him at the same moment.’ And I have found that quite a lot of people feel this. Now, the first thing to notice is that the whole sting of it comes in the words at the same moment. Most of us can imagine God attending to any number of applicants if only they came one by one and He had an endless time to do it in. So what is really at the back of this difficulty is the idea of God having to fit too many things into one moment of time. Well that is of course what happens to us. Our life comes to us moment by moment. One moment disappears before the next comes along: and there is room for very little in each. That is what Time is like. And of course you and I tend to take it for granted that this Time series—this arrangement of past, present and future—is not simply the way life comes to us but the way all things really exist. We tend to assume that the whole universe and God Himself are always moving on from past to future just as we do.
