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.
