I know all about the despair of overcoming chronic temptations. It is not serious, provided self-offended petulance, annoyance at breaking records, impatience etc. don’t get the upper hand. No amount of falls will really undo us if we keep on picking ourselves up each time. We shall of course be very muddy and tattered children by the time we reach home. But the bathrooms are all ready, the towels put out, and the clean clothes in the airing cupboard. The only fatal thing is to lose one’s temper and give it up. It is when we notice the dirt that God is most present in us: it is the very sign of His presence.
The real problem of the Christian life comes where people do not usually look for it. It comes the very moment you wake up each morning. All your wishes and hopes for the day rush at you like wild animals. And the first job each morning consists simply in shoving them all back; in listening to that other voice, taking that other point of view, letting that other larger, stronger, quieter life come flowing in. And so on, all day. Standing back from all your natural fussingsand frettings; coming in out of the wind. We can only do it for moments at first. But from those moments the new sort of life will be spreading through our system: because now we are letting Him work at the right part of us. It is the difference between paint, which is merely laid on the surface, and a dye or stain which soaks right through. He never talked vague, idealistic gas. When He said, ‘Be perfect’, He meant it. He meant that we must go in for the full treatment. It is hard; but the sort of compromise we are all hankering after is harder – in fact, it is impossible. It may be hard for an egg to turn into a bird: it would be a jolly sight harder for it to learn to fly while remaining an egg. We are like eggs at present. And you cannot go on indefinitely being just an ordinary, decent egg. We must be hatched or go bad.
