This is one of my favorite quotes.

It is taken from, "The Weight of Glory", by C.S. Lewis:

Lewis writes, in speaking of the immortality of man:

"It is a serious thing to live in a society of possible gods and goddesses, to remember that the dullest and most uninteresting person you talk to may one day be a creature which, if you saw it now, you would be strongly tempted to worship, or else a horror and a corruption such as you only meet, if ever, only in a nightmare.  All day long we are, in some degree, helping each other to one or the other of these destinations.  It is in the light of these overwhelming possibilities, it is with the awe and the circumspection proper to them, that we should conduct all our dealings with one another, all friendships, all loves, all play, all politics.There are no ordinary people.  You have never talked to a mere mortal.  Nations, cultures, arts, civilizations- these are mortal, and there life is to ours as the life of a gnat.  But it is immortals whom we joke with, work with, marry, snub, and exploit- immortal horrors or everlasting splendours."
