Such is the changeableness of man's will in his unsanctified state. How different is all this from the true and unchangeable foundations of God; — and how different the condition of the unholy man, who rests upon himself, from that of the man who is united with the infinite! On the strong rock of the perpetual identity of the divine will, and not on the uncertain quicksands of a will which is liable to change, the holy man rests his head in peace. No storms terrify him. Knowing, as he does, that to God there is no past and no future, his soul. combining the past and the future into one, may be said to be centered in the eternal present. To Sense, indeed, many things are new. To Faith, nothing is new. To Sense, many things are strange, unprecedented, terrifying. There are storms, diseases, wars, the sky in commotion, the earth heaving, nations destroyed. But to Faith, whose eye penetrates beneath the surface, there is only what was designed to be; the development of a will, which, in being invariably true to mercy, wisdom, and justice, never changes from its own settled line of action, but is identical in its eternity. These present things, which occupy and perplex the senses, are the externalities which clothe the inward life. They may be described as the "veil of the temple," within which there is God without an image, unseen by that external eye which can see only the form of things, but visible to that eye of Faith, which, beneath all outward forms, sees, and knows, and loves the Eternal Essence.
