1. One of the most effectual means of convincing a man of sin is by setting it before him as existing in another person. "Thou art the man!" the story of whose crime has stirred thine indignation and called forth the sentence of death from thy lips. Self-interest, passion, and prejudice, that darken a man's view of his own sin, have comparatively little influence upon him when looking at the sin of another. Here the veil is removed; he sees clearly and judges impartially. For this reason (among others) our Lord "spake many things unto them in parables."

2. The force of truth depends upon the particular application which is made of it. "Thou art the man who hast done this!" (LXX.); against thyself thine indignation should be directed; upon thyself the sentence has been pronounced. It is as if hitherto only the back of the offender was seen, when, suddenly turning round, his face appeared, and David beheld himself! "Men often correctly understand a message of God without observing its personal application to them." Hence the preacher, like the prophet of old (1 Kings 14:7; 1 Kings 18:18; 1 Kings 21:19; 2 Kings 5:26; Daniel 5:22; Matthew 14:4), must directly, wisely, and faithfully apply the truth to his hearers. "'Thou art the man!' is or ought to be the conclusion, expressed or unexpressed, of every practical sermon." What is a sword without a point? "Here also is a lesson to hearers. David listened to a sermon from Nathan, which exactly suited his own case, and yet he did not apply it to himself. He turned the edge of it from himself to another. The benefit of sermons depends more upon the hearer than the preacher. The best sermon is that who hear most, but who apply most what they hear to their own hearts."

3. Every man is responsible to God for the sin which he has committed. "Thou art inexcusable, O man" (Romans 2:1), however thou mayest have persuaded thyself to the contrary. Is the man whom thou judgest accountable for his conduct; and art not thou for thine? Is he accountable to thee? How much more art thou to God? No position, however exalted, can release from responsibility to him or exempt from obedience to his commandment; no constitutional tendency, no temptation, expediency, or necessity be an adequate reason for despising it (Ezekiel 18:4; Romans 3:6).

"And self to take or leave is free,
Feeling its own sufficiency:
In spite of science, spite of fate,
The judge within thee, soon or late,
Will blame but thee, O man!

"Say not. 'I would, but could not. He
Should bear the blame who fashioned me.
Call a mere change of motive choice?'
Scorning such pleas, the inner voice
Cries, 'Thine the deed, O man!'"

(J.A. Symonds.)

4. A messenger of Heaven is always in readiness to single out the sinner, bring his sin to remembrance, and call him to account. "Thus saith the Lord God of Israel," etc. (ver. 7), "Wherefore hast thou despised the commandment of the Lord, to do evil in his sight?" etc. (ver. 9). Every wrong done to man, yea, every sin, is a factual contempt of his commandment (Psalm 51:4). Whilst the supreme King and Judge observes it, and is long suffering towards the doer of it, he provides many witnesses, holds them in reserve, and sends them with his word at the proper moment to declare all its enormity - its ingratitude (ver. 8), presumption (ver. 9), disloyalty before him, its "intense and brutal selfishness," sensuality, cruelty, and craft. Conscience also awakes to confirm their testimony, with "a thousand several tongues, and every tongue" crying, "Thou art the man!"

5. The less expected the charge preferred against the sinner, the more overwhelming his conviction of guilt. "The further David was from thinking of a reference to himself, the greater the force with which the word must have struck him" (Erdmann). There could be no defence, no extenuation, no answer (Acts 24:25; Matthew 22:12).

6. The condemnation which one man pronounces on another sometimes recoils upon himself with increased severity. "Out of thine own mouth," etc. (Luke 19:22). "Now therefore the sword shall never depart from thine house," etc. "For a single moment the features of the king are charged with the expression of astonishment. He gazes eagerly at the prophet like one at a loss to divine his meaning. But, almost instantly, as if an inward light had burst upon his soul, the expression changes to one of agony and horror. The deeds of the last twelve months glare in all their infamous baseness upon him, and outraged justice, with a hundred guttering swords, seems all impatient to devour him" (Blaikie). "O wicked man, thou shalt surely die!" (Ezekiel 33:8).

7. The conviction of sin is the first step in the way of restoration to righteousness. The sense of sin is the beginning of salvation. "He that humbleth himself," etc. (Luke 14:11; 1 John 1:9). "If we would judge ourselves," etc. (1 Corinthians 11:31, 32). Every man must be revealed to himself in the light of God's righteous judgment here or hereafter (Ecclesiastes 11:9; Ecclesiastes 12:14). - D.

I. IT CANNOT BE SAID THAT CONSCIENCE IS DEAD. For no sooner does David hear a story of oppression than his conscience rises majestically in con-detonation of the rich man's execrable tyranny. The conscience was quick and powerful; otherwise it could not have asserted itself so immediately and majestically. Conscience cannot die. There are certain moral truths which shine by their own light and need not that any should bear witness to them. These moral axioms require no proof: they abide for ever in the constitution of man. Just as mathematical axioms, such as "Things which are equal to the same are equal to one another," are accepted by all men as fundamental and final: so there are moral axioms, such as "Honesty is right," or "Truth is right," which require no laboured demonstration, but by their own intrinsic excellence command acceptance at once and by all. These moral intuitions cannot perish. They are a part of man's being. A man may mistake the application or resist the force of these moral certainties, but he never can deny their reality. In this fact lies the hope of the world's salvation. There is in every soul a sense of right and wrong. Prove to any one that he is a sinner, reach the conscience, and redemption is already begun. From this fact, those engaged in Christian work may gather great confidence. Every witness for Christ has a friend in the court of man's nature. A man may be so engrossed with the pursuit of what is merely pleasant or profitable that he may not hear at all, or hear but in a dim and confused way, the warnings and entreaties of the inner monitor, just as a member of the family circle, busy at some book or task, may be so preoccupied with his own thoughts and employment, that he hears and yet does not hear the conversation of those around him, and answers the questions even that may be addressed directly to him in that provokingly dreamy and abstracted manner, characteristic of absent-mindedness. So we hear, even though we may only vaguely heed, the voice of conscience. A man may even encase his conscience in a mailed coat of deliberate and hardened villany, but conscience is still there, a living, breathing immortal entity. At any moment a word, a glance of the eye, a pressure of the hand, may be an arrow to penetrate some joint of the harness. There are many ways of reaching the conscience, as there are many ways of touching the heart. It may be only a brief story, like Nathan's parable, or a single verse, or a child's sermon; but any one is sword enough to pierce the quick sense of right and wrong. Take comfort, then, my fellow-labourer, from this thought that in every man conscience lives, moves, and has its being; and that however closely confined it may be in the dungeon of ignorance or depravity, a word of God can shake the prison as with an earthquake, and wring from the sturdiest keeper's soul the cry, "What must I do to be saved?"

II. BUT LET US GO A LITTLE DEEPER AND ASK, HOW IS IT THAT THOUGH DAVID'S CONSCIENCE WAS IN ITSELF LIVING AND VIGOROUS, IT WAS ACTUALLY SO LONG IN MOVING AGAINST HIMSELF? In endeavouring to answer this question, we must remember that conscience is not an independent faculty. Its judgments are founded on the representations of the mind. The intellect furnishes the premises on which the moral faculty rests its conclusions. If the premises are wrong, the inferences must be erroneous, even though they are in themselves correctly drawn. To be a little more specific, conscience never undertakes to tell me what is honest in a particular case; my own intellect tells me that: but conscience, as soon as the intellect decides what is honest, authoritatively declares that the honest course is right and ought to be pursued. Conscience never says any more. than this, that "honesty, or purity, or veracity is right;" it is for the intellect to state what is honest, or pure, or truthful. Consequently, if the information furnished to the conscience by the intellect is defective, or exaggerated, or distorted, or wholly mistaken, the judgment of conscience will be proportionately in error. The moral axioms are in themselves infallibly correct, but they may be wrongly applied, just as the axioms of mathematics, while infallibly correct in themselves, may be wrongly applied. I turn my intellect to consider certain actions, and I carry, suppose, the assurance to my conscience that these are honest add those dishonest. Immediately conscience, acting on the information of the intellect, asserts that the former are right and the latter wrong. But if the intellect is mistaken, conscience must be correspondingly mistaken. Conscience is like an eye, which is round and good m itself, but which is compelled to look on men and things through the window of the understanding. If the intervening glass is not pure and spotless, if it is coloured or discoloured, the external world will, to my eye, be tinged or blurred accordingly; or if this pane is marred by a knot, that one by a bubble, that other by an abnormal curve, all by some defect, then my view will be distorted, nature will be twisted out of shape, in accordance with the character of the medium. Yet the fault is not in my organ of vision or in the outside world, but in the interposing panes of glass. Herein lies the possibility of two consciences, equally good and true in themselves, giving totally opposite, or widely diverse, decisions on the very same data. An easy conscience, therefore, is not always a safe guide. A man may fight even against God with a perfectly clear conscience: a man may go to hell with a perfectly clear conscience. There is a story told by John Foster in one of his essays of a wicked and traitorous naval captain, who, unable to coax or coerce his sailors into a vile surrender to the foe, concealed a large loadstone at a little distance from the needle. The sailors, unaware of the cruel trick played' upon them, steered their vessel faithfully by the compass, but to their degradation and destruction, for their misplaced confidence carried them directly into a hostile port and the enemy's pitiless hands. Yet all the while these misguided mariners thought that all was well because they were steering by the compass. And, indeed, the needle was right in itself, tremblingly sensitive, ready to point in the proper direction if it had not been tampered with, if it had not been turned aside from its true bearing by an influence that the hapless crew wot not of. Just so many a one is going to ruin, shaping his course, as he thinks, by conscience; but it is a conscience directed, or rather misdirected, by a darkened mind, an evil heart, a sinful will. Thus, many a man, who has not yet had his heart changed, manages to say to himself, "Peace, peace," when there is no peace. Certainly all should believe in Christ; but does not he believe in Christ? So he keeps interpreting or misinterpreting matters to his conscience; so conscience is soothed; so the sinner, often a respectable, well-clad, high-toned, pure-minded sinner, is lost. It is thus possible for us to keep saying, "Peace, peace," until by mere reiteration we come to believe our assertion. It is proverbial that a man may tell a lie so often that he comes at last to believe his own falsehood; and a soul may be at ease in Zion, the conscience reposing on a specious and comfortable falsehood or half truth, which frequent repetition clothes with an air of authority. What reason, then, in view of the awful possibility of being self-deceived, we have for scrutinising and re-scrutinising our outward conduct, and as for the inner man humbly and earnestly we should cry to God each for himself: "O Lord, teach me Thy way. Lead in a plain path, for I know nothing as I ought to know. Search me, O God, and know my heart, try me and know my thoughts: and see if there be any wicked way in me, and lead me in the way everlasting."

III. BUT STILL THE QUESTION RECURS, HOW IS IT POSSIBLE FOR A MAN LIKE DAVID TO BE GUILTY, LIKE DAVID, OF MOST ABOMINABLE CRIMES, AND YET SOOTHE HIS CONSCIENCE INTO QUIETNESS? We can understand a man misinterpreting actions that are not palpably and notoriously evil, where there may be room for mistake and misapprehension, and so furnishing his conscience with misleading information. But how is it possible for one, like David, to perpetrate the enormities of which he was guilty and yet remain easy in his mind? How could he by any chance so misreport the facts of such a glaring case to the impartial tribunal within? Here we enter on one of the most solemn subjects that could be considered, the blinding influence of the love of self. Love is notoriously blind: and self-love — the most subtle, ineradicable of all loves — is the blindest of all, so that even if our hands, like David's, be steeped in blood, we have still some excuse to offer for ourselves. It is this love of self that makes us very conscious of the changes that take place in our neighbour's appearance, but slow to note our own. We see the pallor of disease, the wrinkles of care, or the whitening of old age, far more readily in others than in ourselves. Loathsome diseases are far more bearable in ourselves than in others. What would be tedious and offensive in others is perfectly tolerable in ourselves. So in spiritual things, we can behold the motelike splinter in our neighbour's eye, but the weaver's beam in our own we may not discern. I knew two men, occupying good social positions, who were unhappily addicted to drink, They lived in the same town, and their families were very intimate. Each of them was blessed with an excellent wife. Again and again have I heard each of these men in turn, when he happened to be sober and his neighbour was indulging in a bout of drinking, railing at the drunken husband over the way, and pitying the splendid woman who had the misfortune-to be tied to such a soil all this in tones of unquestioned sincerity. What is the explanation of this? In judging ourselves we have the love of self on our side as a special pleader. David may have said to himself: "I was very idle, and Bathsheba was very beautiful. I was specially tempted." Or he may have flattered himself with the thought: " After all, I did not kill Uriah. I did indeed order him to be put in a place of danger, but some one had to stand in the forefront of the battle, and why not he as well as another? Moreover, is not Uriah a Hittite? Is he not one of a race that we are authorised to exterminate?" Or he may have soothed his conscience with the notion that if he had done wrong to Uriah it was for no merely selfish purpose, but in order as far as possible to recompense Bathsheba for the injury inflicted on her. Possibly by some such arguments, at all events by some subtle reasonings and excuses, dictated by the love of self and the pride of life, he succeeded in veiling the filthiness of his conduct from the clear eye of the moral faculty. What a commentary is all this on the blindness of man to his personal guilt! Here was one, who had been wont to live in close and happy fellowship with God, and vet yielded to and lived in flagrant sin for a long time, without apparently being conscious of its vileness. Ah, beloved, do we not stand sorely in need of some one who will tell us the truth about ourselves? Is Christ our enemy because He tells us the truth? There is in reality in every one of us the seeds of thoroughgoing depravity. If we say that we have not the principle of sin we simply deceive ourselves. The principle of sin may take divers forms, varying according to men's training, opportunities, hereditary tendencies, peculiar temptations, associates, and such like; but, whatever form it takes, the principle is there. What varied manifestations there are of matter in nature. There it is in the clouds, in the rushing wind, in the gas lighter than air, in the flowing river and the restless ocean, in the green field and the snow-capped mountain, in the pebble from the brook and the rock dug from the quarry. Analyse these multitudinous forms, and you will find all alike in essence; there is one elementary substance throughout all this manifoldness.
