"Already the new men are dotted here and there all over the earth. Some, as I have admitted, are still hardly recognisable: but others can be recognised. Every now and then one meets them. Their very voices and faces are different from ours: stronger, quieter, happier, more radiant. They begin where most of us leave off. They are, I say, recognisable; but you must know what to look for. They will not be very like the idea of 'religious people' which you have formed from your general reading. They do not draw attention to themselves. You tend to think that you are being kind to them when they are really being kind to you. They love you more than other men do, but they need you less. (We must get over wanting to be needed: in some goodish people, specially women, that is the hardest of all temptations to resist.) They will usually seem to have a lot of time: you will wonder where it comes from. When you have recognised one of them, you will recognise the next one much more easily. And I strongly suspect (but how should I know?) that they recognise one another immediately and infallibly, across every barrier of colour, sex, class, age, and even of creeds. In that way, to become holy is rather like joining a secret society. To put it at the very lowest, it must be great fun."
