What is this questioning nothing holds away, nothing stills, and nothing wears out? It is the voice of God Himself, and its insistence is therefore as irresistible as its effect is universal. That is not mere rhetoric which opens the Lord's controversy: Hear, O heavens, and give ear, O earth, for the Lord hath spoken. All the world changes to the man in whom conscience lifts up her voice, and to the guilty Nature seems attentive and aware. Conscience compels heaven and earth to act as her assessors, because she is the voice, and they the creatures, of God. This leads us to emphasize another feature of the prophecy.
We have called this chapter a trial-at-law; but it is far more a personal than a legal controversy; of the formally forensic there is very little about it. Some theologies and many preachers have attempted the conviction of the human conscience by the technicalities of a system of law, or by appealing to this or that historical covenant, or by the obligations of an intricate and burdensome morality. This is not Isaiah's way. His generation is here judged by no system of law or ancient covenants, but by a living Person and by His treatment of them—a Person who is a Friend and a Father. It is not Judah and the law that are confronted; it is Judah and Jehovah. There is no contrast between the life of this generation and some glorious estate from which they or their forefathers have fallen; but they are made to hear the voice of a living and present God: I have nourished and brought up children, and they have rebelled against Me. Isaiah begins where Saul of Tarsus began, who, though he afterwards elaborated with wealth of detail the awful indictment of the abstract law against man, had never been able to do so but for that first confronting with the Personal Deity, Saul, Saul, why persecutest thou Me? Isaiah's ministry started from the vision of the Lord; and it was no covenant or theory, but the Lord Himself, who remained the prophet's conscience to the end.
But though the living God is Isaiah's one explanation of conscience, it is God in two aspects, the moral effects of which are opposite, yet complementary. In conscience men are defective by forgetting either the sublime or the practical, but Isaiah's strength is to do justice to both. With him God is first the infinitely High, and then equally the infinitely Near. The Lord is exalted in righteousness! yes, and sublimely above the people's vulgar identifications of His will with their own safety and success, but likewise concerned with every detail of their politics and social behaviour, not to be relegated to the Temple, where they were wont to confine Him, but by His prophet descending to their markets and councils, with His own opinion of their policies, interfering in their intrigues, meeting Ahaz at the conduit of the upper pool in the highway of the fuller's field, and fastening eyes of glory on every pin and point of the dress of the daughters of Zion. He is no merely transcendent God. Though He be the High and Holy One, He will discuss each habit of the people, and argue upon its merits every one of their policies. His constant cry to them is Come and let us reason together, and to hear it is to have a conscience. Indeed, Isaiah lays more stress on this intellectual side of the moral sense than on the other, and the frequency with which in this chapter he employs the expressions know, and consider, and reason, is characteristic of all his prophesying. Even the most superficial reader must notice how much this prophet's doctrine of conscience and repentance harmonizes with the metanoia of New Testament preaching.
This doctrine, that God has an interest in every detail of practical life and will argue it out with men, led Isaiah to a revelation of God quite peculiar to himself. For the Psalmist it is enough that his soul come to God, the living God. It is enough for other prophets to awe the hearts of their generations by revealing the Holy One; but Isaiah, with his intensely practical genius, and sorely tried by the stupid inconsistency of his people, bends himself to make them understand that God is at least a reasonable Being. Do not, his constant cry is, and he puts it sometimes in almost as many words—do not act as if there were a Fool on the throne of the universe, which you virtually do when you take these meaningless forms of worship as your only intercourse with Him, and beside them practise your rank iniquities, as if He did not see nor care. We need not here do more than mention the passages in which, sometimes by a word, Isaiah stings and startles self-conscious politicians and sinners beetle-blind in sin, with the sense that God Himself takes an interest in their deeds and has His own working-plans for their life. On the land question in Judah (v. 9): In mine ears, saith the Lord of hosts. When the people were paralyzed by calamity, as if it had no meaning or term (xxviii. 29): This also cometh forth from the Lord of hosts, which is wonderful in counsel and excellent in effectual working. Again, when they were panic-stricken, and madly sought by foolish ways their own salvation (xxx. 18): For the Lord is a God of judgement—i.e., of principle, method, law, with His own way and time for doing things—blessed are all they that wait for Him. And again, when politicians were carried away by the cleverness and success of their own schemes (xxxi. 2): Yet He also is wise, or clever. It was only a personal application of this Divine attribute when Isaiah heard the word of the Lord give him the minutest directions for his own practice—as, for instance, at what exact point he was to meet Ahaz (vii. 3); or that he was to take a board and write upon it in the vulgar character (viii. 1); or that he was to strip frock and sandals, and walk without them for three years (xx). Where common men feel conscience only as something vague and inarticulate, a flavour, a sting, a foreboding, the obligation of work, the constraint of affection, Isaiah heard the word of the Lord, clear and decisive on matters of policy, and definite even to the details of method and style.
Isaiah's conscience, then, was perfect, because it was two-fold: God is holy; God is practical. If there be the glory, the purity as of fire, of His Presence to overawe, there is His unceasing inspection of us, there is His interest in the smallest details of our life, there are His fixed laws, from regard for all of which no amount of religious sensibility may relieve us. Neither of these halves of conscience can endure by itself. If we forget the first we may be prudent and for a time clever, but will also grow self-righteous, and in time self-righteousness means stupidity too. If we forget the second we may be very devotional, but cannot escape becoming blindly and inconsistently immoral. Hypocrisy is the result either way, whether we forget how high God is or whether we forget how near.
To these two great articles of conscience, however—God is high and God is near—the Bible adds a greater third, God is Love. This is the uniqueness and glory of the Bible's interpretation of conscience. Other writings may equal it in enforcing the sovereignty and detailing the minutely practical bearings of conscience: the Bible alone tells man how much of conscience is nothing but God's love. It is a doctrine as plainly laid down as the doctrine about chastisement, though not half so much recognised—Whom the Lord loveth He chasteneth. What is true of the material pains and penalties of life is equally true of the inward convictions, frets, threats and fears, which will not leave stupid man alone. To men with their obscure sense of shame, and restlessness, and servitude to sin the Bible plainly says, "You are able to sin because you have turned your back to the love of God; you are unhappy because you do not take that love to your heart; the bitterness of your remorse is that it is love against which you are ungrateful." Conscience is not the Lord's persecution, but His jealous pleading, and not the fierceness of His anger, but the reproach of His love. This is the Bible's doctrine throughout, and it is not absent from the chapter we are considering. Love gets the first word even in the indictment of this austere assize: I have nourished and brought up children, and they have rebelled against Me. Conscience is already a Father's voice: the recollection, as it is in the parable of the prodigal, of a Father's mercy; the reproach, as it is with Christ's lamentation over Jerusalem, of outraged love. We shall find not a few passages in Isaiah, which prove that he was in harmony with all revelation upon this point, that conscience is the reproach of the love of God.
But when that understanding of conscience breaks out in a sinner's heart forgiveness cannot be far away. Certainly penitence is at hand. And therefore, because of all books the Bible is the only one which interprets conscience as the love of God, so is it the only one that can combine His pardon with His reproach, and as Isaiah now does in a single verse, proclaim His free forgiveness as the conclusion of His bitter quarrel. Come, let us bring our reasoning to a close, saith the Lord. Though your sins be as scarlet, they shall be white as snow; though they be red like crimson, they shall be as wool. Our version, Come, and let us reason together, gives no meaning here. So plain an offer of pardon is not reasoning together; it is bringing reasoning to an end; it is the settlement of a dispute that has been in progress. Therefore we translate, with Mr. Cheyne, Let us bring our reasoning to an end. And how pardon can be the end and logical conclusion of conscience is clear to us, who have seen how much of conscience is love, and that the Lord's controversy is the reproach of His Father's heart, and His jealousy to make His own consider all His way of mercy towards them.
But the prophet does not leave conscience alone with its personal and inward results. He rouses it to its social applications. The sins with which the Jews are charged in this charge of the Lord are public sins. The whole people is indicted, but it is the judges, princes and counsellors who are denounced. Judah's disasters, which she seeks to meet by worship, are due to civic faults, bribery, corruption of justice, indifference to the rights of the poor and the friendless. Conscience with Isaiah is not what it is with so much of the religion of to-day, a cul de sac, into which the Lord chases a man and shuts him up to Himself, but it is a thoroughfare by which the Lord drives the man out upon the world and its manifold need of him. There is little dissection and less study of individual character with Isaiah. He has no time for it. Life is too much about him, and his God too much interested in life. What may be called the more personal sins—drunkenness, vanity of dress, thoughtlessness, want of faith in God and patience to wait for Him—are to Isaiah more social than individual symptoms, and it is for their public and political effects that he mentions them. Forgiveness is no end in itself, but the opportunity of social service; not a sanctuary in which Isaiah leaves men to sing its praises or form doctrines of it, but a gateway through which he leads God's people upon the world with the cry that rises from him here: Seek justice, relieve the oppressed, judge the fatherless, plead for the widow.
Before we pass from this form in which Isaiah figures religion we must deal with a suggestion it raises. No modern mind can come into this ancient court of the Lord's controversy without taking advantage of its open forms to put a question regarding the rights of man there. That God should descend to argue with men, what licence does this give to men? If religion be reasonable controversy of this kind, what is the place of doubt in it? Is not doubt man's side of the argument? Has he not also questions to put—the Almighty from his side to arraign? For God has Himself here put man on a level with Him, saying, Come, and let us reason together.
A temper of this kind, though not strange to the Old Testament, lies beyond the horizon of Isaiah. The only challenge of the Almighty which in any of his prophecies he reports as rising from his own countrymen is the bravado of certain drunkards (chaps. v. and xxviii.). Here and elsewhere it is the very opposite temper from honest doubt which he indicts—the temper that does not know, that does not consider. Ritualism and sensualism are to Isaiah equally false, because equally unthinking. The formalist and the fleshly he classes together, because of their stupidity. What does it matter whether a man's conscience and intellect be stifled in his own fat or under the clothes with which he dresses himself? They are stifled, and that is the main thing. To the formalist Isaiah says, Israel doth not know, my people doth not consider; to the fleshly (chap. v.), My people are gone into captivity for want of knowledge. But knowing and considering are just that of which doubt, in its modern sense, is the abundance, and not the defect. The mobility of mind, the curiosity, the moral sensitiveness, the hunger that is not satisfied with the chaff of formal and unreal answers, the spirit to find out truth for one's self, wrestling with God—this is the very temper Isaiah would have welcomed in a people whose sluggishness of reason was as justly blamed by him as the grossness of their moral sense. And if revelation be of the form in which Isaiah so prominently sets it, and the whole Bible bears him out in this—if revelation be this argumentative and reasonable process, then human doubt has its part in revelation. It is, indeed, man's side of the argument, and as history shows, has often helped to the elucidation of the points at issue.
