I like the marginal rendering of the introductory sentence of this great chapter. "_Faith is the giving substance to things hoped for._" Faith converts cloudy castles into substantial homes. Faith substantiates the unseen. Faith sucks the energy out of splendid ideals, and incorporates it in present and immediate life. Faith unfolds the eternal in the moment, the infinite in the trifle, the divine in the commonplace. Faith incorporates God and man. Yes, faith gives substance to "things hoped for," it brings them out of the air, and gives them reality and movement in the hard and common ways of earth and time. And faith is also "_the test of things not seen_." By a test faith gains a conquest. By an experiment faith acquires an experience. By a great speculation faith makes a great discovery. "Try me now herewith, and prove Me!" It is an invitation to humble and sincere assumption. Try if it works! Make a hallowed experiment with the powers of grace. Lord, incline me to make the gracious test! Let me stake my all upon the venture! Let me dare all in order that I may gain all! Let me sow bountifully, and so reap a bountiful harvest. SEPTEMBER The Eighth _THE BRACING AIR OF PUBLICITY_ ROMANS x. 1-13. There is a belief which never registers itself in confession. It never exercises itself in the strong, bracing air of publicity. It is a cloistered belief, and suffers from want of ventilation. Such Christians are always anæmic; indeed, they are always puny, and never get beyond the stage of spiritual babyhood. "Ye are yet babes!" Belief which is never oxygenated by open confession can never nourish the soul into vigorous and exhilarant health. But there is a belief which expresses and confirms itself in confession. "_With the mouth confession is made unto salvation._" Such confession is a means of moral and spiritual health. And confession in the early days meant risk, venture which exposed the life to the shedding of blood. It meant a frank defiance of the world, and an eager challenge of the devil. And it is on such fields of open encounter for the Lord that muscle is made, and the soul goes "from strength to strength," and "from glory to glory." My soul, art thou secretly ashamed of thy Lord? Art thou afraid to "lift high His royal banner"? Then thou wilt always be as a feather-bed soldier, and the trophies of the honourable war are not for thee. Stand out in the open, and boldly testify, "As for me and my house, we will serve the Lord!" SEPTEMBER The Ninth _DEALING WITH SIN_ PSALM xxxii. Here is the burden of unconfessed sin. "_When I kept silence my bones waxed old._" There is nothing brings on premature age like secret sin. It keeps the mind in perpetual unrest, and a troubled mind soon makes the body old. The real nourisher of the body is a quiet and radiant soul. But let the soul be in chaos, and the body will soon be a ruin.
