"It is the highest activity of the human soul, and therefore it is at the same time the ultimate test of a man’s true spiritual condition. There is nothing that tells the truth about us as Christian people so much as our prayer life. . . . Ultimately, therefore, a man discovers the real condition of his spiritual life when he examines himself in private, when he is alone with God. . . . And have we not all known what it is to find that, somehow, we have less to say to God when we are alone than when we are in the presence of others? It should not be so; but it often is. So that it is when we have left the realm of activities and outward dealings with other people, and are alone with God, that we really know where we stand in a spiritual sense."
