It is an experience all men have to make, an experience that grows with age and deepens with wisdom, as we more and more encounter the mysteries of existence, and fathom the shallowness of our fancied knowledge. What do we know of God, the world, ourselves? How much, and how little! How much about them, how little of them! Who of us, for instance, has any actual conception of God in His absolute being? You remember how in dreamy childhood you would vainly strive to arrest and fasten in some definite image the vague vision of dazzling glory you had learned to call God, which floated before your soul, awing you with its majesty and immeasurable beauty, but evading every effort to grasp it. With gathering years and widening horizon you watched the world's changeful aspects and ceaseless movements, till nature seemed the transparent vesture of its mighty Maker, but it was all in vain that you tried to pierce the thin veil and behold the invisible Worker within. You took counsel with science, and it told you much concerning the properties of matter and the sequences of force, but the ultimate cause, that which is beneath, that which worketh all in all, it could not reveal. You turned to philosophy, and you traced the soaring thoughts of the sages, that rushed upward like blazing rockets, as if they would pierce and illuminate the remotest heaven; but you saw how, ere they reached that far goal, their fire went out, their light was quenched, and they fell back through the darkness, baffled and spent. You betook yourself to revelation, counting that at last you were entering the inner shrine, and you did indeed learn much that was new and precious; but soon came the discovery that here also we do but see through a glass darkly, and that our best knowledge of God is no more than a knowledge in part. "Lo, these are but the outskirts of His ways; and how small a portion we know of them! But the thunder of His power, who can understand?" We are, as it were, surrounded on every hand by mighty mountain peaks, whose rocky sides foil every effort to explore the pinnacles that lie hidden in distant cloud and mist. The achievements of the human intellect are many and marvellous, but above and beyond its realm remain, and doubtless ever shall remain, "great matters, and things too high" for us. II. Read Ps. xxxvii., and Matt. xi. THE SECRET OF REST. "Lord, my heart is not haughty, nor mine eyes lofty."
