And still further, looking at the one deed, he sees in it something more than an isolated act. It leads him down to its motive; that motive carries him to the state of mind in which it could have power; that state of mind, in which the motive could have power, carries him still deeper to the bias of his nature as he had received it from his parents. And thinking of how he had fallen, how upon his terraced palace roof there the eye had inflamed the heart, and the heart had yielded so quickly to the temptations of the eye, he finds no profounder explanation of the disastrous eclipse of goodness than this: 'Behold! I was shapen in iniquity.'
Is that a confession or a palliation, do you think? Is he trying to shuffle off guilt from his own shoulders? By no means, for these words are the motive for the prayer, 'Purge me, and I shall be clean.' That is to say, he has learned that isolated acts of sin inhere in a common root, and that root a disposition inherited from generation to generation to which evil is familiar and easy, to which good, alas! is but too alien and unwelcome. None the less is the evil done _his_ deed. None the less has he to wail in full consciousness of his individual responsibility: 'Against Thee have _I_ sinned.' But the effect of this second discovery, that sin has become so intertwisted with his being that he cannot shake off the venomous beast into the fire and feel no harm, is the same as that of the former--to drive him to God, who alone can heal the nature and separate the poison from his blood.
Dear friends! there are some of you who are wasting your lives in paroxysms of fierce struggle with the evil that you have partially discovered in yourselves, alternating with long languor, fits of collapse and apathy, and who make no solid advance, just because you will not lay to heart these two convictions--your sin has to do with God, and your sins come from a sinful nature. Because of the one fact, you must go to God for pardon; because of the other, you must go to God for cleansing. There, in your heart, like some black well-head in a dismal bog, is the source of all the swampy corruption that fills your life. You cannot stanch it, you cannot drain it, you cannot sweeten it. Ask Him, who is above your nature and without it, to change it by His own new life infused into your spirit. He will heal the bitter waters. He alone can. Sin is against God; sin comes from an evil heart; therefore, if your longings for that ideal perfectness are ever to be fulfilled, you must make prayers of them, and cry to Him who hears, 'Create in me a clean heart, O God! take not Thy Holy Spirit from me.'
III. Finally, observe that prayers for perfect cleansing are permitted to the lips of the greatest sinners.
Such longings as these might seem audacious, when the atrocity of the crime is remembered, and by man's standard they are so. Let the criminal be thankful for escape, and go hide himself, say men's pardons. But here is a man, with the evil savour of his debauchery still tainting him, daring to ask for no mere impunity, but for God's choicest gifts. Think of his crime, think of its aggravations from God's mercies to him, from his official position, from his past devotion. Remember that this cruel voluptuary is the sweet singer of Israel, who had taught men songs of purer piety and subtler emotion than the ruder harps of older singers had ever flung from their wires. And this man, so placed, so gifted, set up on high to be the guiding light of the nation, has plunged into the filth of these sins, and quenched all his light there. When he comes back penitent, what will he dare to ask? Everything that God can give to bless and gladden a soul. He asks for God's Spirit, for His presence, for the joy of His salvation; to be made once again, as he had been, the instrument that shall show forth His praise, and teach transgressors God's ways. Ought he to have had more humble desires? Does this great boldness show that he is leaping very lightly over his sin? Is he presumptuous in such prayers? God be thanked--no! But, knowing all his guilt, and broken and contrite in heart (crushed and ground to powder, as the words mean), utterly loathing himself, aware of all the darkness of his deserts, he yet cherishes unconquerable confidence in the pitying love of God, and believes that in spite of all his sin, he may yet be pure as the angels of heaven--ay, even holy as God is holy.
