It is, of course, clear enough that physical facts and phenomena are here described in popular language as they appear to the eye, and by no means with the severe precision of a scientific treatise. It is not to be supposed that this prophet knew more about the actual constitution of the physical universe than the wise men of his time could impart. But such knowledge was not necessary to the enforcement of the spiritual truths which it was his mission to proclaim; and the fact that his brief oracle presents those truths in a garb which we can only regard as poetical, and which it would argue a want of judgment to treat as scientific prose, does not affect their eternal validity, nor at all impair their universal importance. The passage refers us to God as the ultimate source of the world of nature. It teaches us that the stability of things is a reflexion of His eternal being; that the persistence of matter is an embodiment of His strength; that the indestructibility which science ascribes to the materials of the physical universe is the seal which authenticates their Divine original. Persistence, permanence, indestructibleness, are properly sole attributes of the eternal Creator, which He communicates to His creation. Things are indestructible as regards man, not as regards the Author of their being.
Thus the wisdom enshrined in the laws of the visible world, all its strength and all its stability, is a manifestation of the Unseen God. Invisible in themselves, the eternal power and godhead of Iahvah become visible in His creation. And, as the Hebrew mode of expression indicates, His activity is never suspended, nor His presence withdrawn. The conflict of the elements, the roar of the thunder, the flash of the lightning, the downpour of waters, the rush of the stormwind, are His work; and not less His work, because we have found out the "natural" causes, that is, the established conditions of their occurrence; not less His work, because we have, in the exercise of faculties really though remotely akin to the Divine Nature, discovered how to imitate, or rather mimic, even the more awful of these marvellous phenomena. Mimicry it cannot but appear, when we compare the overwhelming forces that rage in a tropical storm with our electric toys. The lightnings in their glory and terror are still God's arrows, and man cannot rob His quiver.
Nowadays more is known about the machinery of the world, but hardly more of the Intelligence that contrived it, and keeps it continually in working order, nay, lends it its very existence. More is known about means and methods, but hardly more about aims and purposes. The reflexion, how few are the master-conceptions which modern speculation has added to the treasury of thought, should suggest humility to the vainest and most self-confident of physical inquirers. In the very dawn of philosophy the human mind appears to have anticipated as it were by sudden flashes of insight some of the boldest hypotheses of modern science, including that of Evolution itself.
The unchangeable or invariable laws of nature, that is to say, the uniformity of sequence which we observe in physical phenomena, is not to be regarded as a thing that explains itself. It is only intelligible as the expression of the unchanging will of God. The prophet's word is still true. It is God who "causes the vapours to rise from the end of the earth," drawing them up into the air from oceans and lakes by the simple yet beautiful and efficient action of the solar heat; it is God who "makes lightnings for the rain," charging the clouds with the electric fluid, to burst forth in blinding flashes when the opposing currents meet. It is God who "brings the wind out of His treasuries." In the prophet's time the winds were as great a mystery as the thunder and lightning; it was not known whence they came nor whither they went. But the knowledge that they are but currents of air due to variations of temperature does not really deprive them of their wonder. Not only is it impossible, in the last resort, to comprehend what heat is, what motion is, what the thing moved is. A far greater marvel remains, which cries aloud of God's wisdom and presence and sovereignty over all; and that is the wonderful consilience of all the various powers and forces of the natural world in making a home for man, and enabling so apparently feeble a creature as he to live and thrive amidst the perpetual interaction and collision of the manifold and mighty elements of the universe.
The true author of all this magnificent system of objects and forces, to the wonder and the glory of which only custom can blind us, is the God of the prophet. This sublime, this just conception of God was possible, for it was actually realized, altogether apart from the influence of Hellenic philosophy and modern European science. But it was by no means as common to the Semitic peoples. In Babylon, which was at the time the focus of all earthly wisdom and power, in Babylon the ancient mother of sciences and arts, a crude polytheism stultified all the wisdom of the wise, and lent its sanction to a profound moral corruption. Rapid and universal conquests, enormous wealth accruing from the spoils and tributes of all nations, only subserved the luxury and riotous living which issued in a general effeminacy and social enervation; until the great fabric of empire, which Nabopalassar and Nebuchadrezzar had reared by their military and political genius, sank under the weight of its own vices.
Looking round upon this spectacle of superstitious folly, the prophet declares that all men are become too brute-like for knowledge; too degraded to appreciate the truth, the simplicity of a higher faith; too besotted with the worship of a hundred vain idols, which were the outward reflexion of their own diseased imaginations, to receive the wisdom of the true religion, and to perceive especially the truth just enunciated, that it is Iahvah who gives the rain and upon whom all atmospheric changes depend (cf. xiv. 22): and thus, in the hour of need, every founder blushes for the image, because his molten figure is a lie, and there is no breath in them; because the lifeless idol, the work of his hands, can lend no help. Perhaps both clauses of the verse rather express a prophecy: All men will be proven brutish, destitute of knowledge; every founder will blush for the graven image. Wise and strong as the Babylonians supposed themselves to be, the logic of events would undeceive them. They were doomed to a rude awakening; to discover in the hour of defeat and surrender that the molten idol was a delusion, that the work of their hands was an embodied lie, void of life, powerless to save. Vanity—a mere breath, nought—are they, a work of knaveries (a term recurring only in li. 18; the root seems to mean "to stammer," "to imitate"); in the time of their visitation they will perish! or simply they perish!—in the burning temples, in the crash of falling shrines.
It has happened so. At this day the temples of cedar and marble, with their woodwork overlaid with bronze and silver and gold, of whose glories the Babylonian sovereigns so proudly boast in their still existing records, as "shining like the sun, and like the stars of heaven," are shapeless heaps or rather mountains of rubbish, where Arabs dig for building materials and treasure trove, and European explorers for the relics of a civilisation and a superstition which have passed away for ever. "Vana sunt, et opus risu dignum." In the revolutions of time, which are the outward measures of the eternally self-unfolding purposes of God, the word of the Judean prophets has been amply fulfilled. Babylon and her idols are no more.
All other idols, too, must perish in like manner. Thus shall ye say of them: The gods who the heavens and earth did not make, perish from the earth and from under the heavens shall these! The assertion that the idols of Babylon were doomed to destruction, was not the whole of the prophetic message. It is connected with and founded upon the antithetic assertion of the eternity of Iahvah. They will perish, but He endures. The one eternal is El Elyon, the Most High God, the Maker of heaven and earth. But heaven and earth and whatever partakes only of their material nature are also doomed to pass away. And in that day of the Lord, when the elements melt with fervent heat, and the earth and the works that are therein shall be burnt up (2 Pet. iii. 10), not only will the idols of the heathen world, and the tawdry dolls which a degenerate church suffers to be adored as a kind of magical embodiment of the Mother of God, but all other idols which the sensebound heart of man makes to itself, vanish into nothingness before that overwhelming revelation of the supremacy of God.
