This work begins: "There are two spheres of knowledge in which every one who is endeavouring after any growth in the spiritual life must be making some advance. The knowledge of God and the knowledge of self. We can all readily perceive the necessity of growth in the knowledge of God as essential to any development of the spiritual life. The connection is obvious. "This," said our Lord, " is life eternal, that they might know Thee, the only true God, and Jesus Christ Whom Thou hast sent." A certain moral sympathy is absolutely necessary as a condition of friendship, and holiness consists in friendship with God. If we would be in any sense the friends of God, we must have at least that desire for holiness without which such friendship would be impossible, the growth in the knowledge of God is the deepening of this friendship. " If we say that we have fellowship with Him and walk in darkness, we lie and do not the truth."" And let us consider self-discipline: "Whatever we may be able to learn from the study of Nature, whether of art or science, all that we know of good and evil, and of the great moral struggle, we know through our own nature alone. So imbued are our minds with moral ideas that we seem to see them reflected in the world of Nature, but it is only that extraordinary responsiveness with which she always meets man. It is a strange thing when we come to analyse it, that so much light and shade, so many lines and curves, so much inanimate matter, should be able in such an extraordinary way to reflect the mind of man, that we even transfer to it our own moral ideas and struggles. Who has not felt that not only can the skies and the earth and the winds rejoice with us in our joys and sorrow with our sorrows, but that they echo our stormy passions, and reflect our wrath and rebellion and cruelty, and melt with us into tears of penitence and sing with us our Te Deums." Here is a salient point: "Self-knowledge apart from God can indeed only lead to despair. For he who has sunk to earth knows well he can find no lever on ear.h or within himself to raise him. How can he? How can anything within himself raise him above himself? How can anything on earth raise him above the earth? Like the piece of silver, in the Parable, that has fallen to the earth, he needs the Hand of Another to raise him."
