Our spiritual life is his affair; because, whatever we may think to the contrary, it is really produced by his steady attraction, and our humble and self-forgetful response to it. It consists in being drawn, at his pace and in his way, to the place where he wants us to be; not the place we fancied for ourselves. For a spiritual life is simply a life in which all that we do comes from the centre, where we are anchored in God: a life soaked through and through by a sense of his reality and claim, and selfgiven to the great movement of his will.
Most of our conflicts and difficulties come from trying to deal with the spiritual and practical aspects of our life separately instead of realising them as parts of one whole. If our practical life is centred on our own interests, cluttered up by possessions, distracted by ambitions, passions, wants and worries, beset by a sense of our own rights and importance, or anxieties for our own future, or longings for our own success, we need not expect that our spiritual life will be a contrast to all this. The soul’s house is not built on such a convenient plan: there are few soundproof partitions in it.
