Sin in the slums is gross and terrible. It staggers down the streets, blasphemes with oaths that can be heard, wallows in vice unmentionable by modest lips. Then some day prosperity may visit it. It moves to a finer residence, seeks the suburbs, or finds domicile on a college campus. It changes all its clothes. No longer is it indecent and obscene. Its speech is mild, its civility is irreproachable. It gathers a company of friends who minister to pleasure and respectability, and the cry of the world's need dies unheard at its peaceful door. It presses its face continually through the pickets of social allowance, like a bad boy who wishes to trespass on forbidden ground but fears the consequence. Its goodness is superficial seeming; at heart it is as bad as it dares to be. It has completely changed its garments, but it is the same sin—indulgent, selfish, and unclean. Sin, as anyone can easily observe, takes a very high polish.

Neither by calling sin an ecclesiastical concern nor by covering its presence in ourselves with pleasant euphemisms can we hide its deadly bane in human life. The truth and import of this negative statement become clear and convincing when its positive counterpart is faced. The world needs goodness. The one thing in which mankind is poor and for the lack of which great causes lag and noble hopes go unfulfilled is character. With each access of that humanity leaps forward; with the sag of that all else is failure. And the one name for every loss and lack and ruin of character is sin. That is our enemy. Upon the defeat of that all our dearest hopes depend, and in its victory every dream of good that the race has cherished comes to an end.

The urgency of this truth is manifest when we note the consequence of sin in our own lives. No statement from antiquity has accumulated more confirming evidence in the course of the centuries than the Psalmist's cry, "My sins are mightier than I." Let us consider its truth in the light of our experience.

Our sins are stronger than we are in their power to fasten on us a sense of guilt that we cannot shake off. Sinful pleasures lure us only in anticipation, dancing before us like Salome before her uncle, quite irresistible in fascination. Happiness seems altogether to depend upon an evil deed. But on the day that deed, long held in alluring expectation, is actually done—how swift and terrible the alteration in its aspect! It passes from anticipation, through committal, into memory, and it never will be beautiful again. We lock it in remembrance, as in the bloody room of Bluebeard's palace, where the dead things hung; at the thought of it we shrink and yet to it our reminiscence continually is drawn. Something happens in us as automatic as the dropping of a loosened apple from a tree; all the laws of the moral universe conspire to further it and we have no power to prevent: sin becomes guilt. When on a lonely ocean the floating bell-buoys toll, no human hands cause them to ring; the waste of an unpeopled ocean surrounds them everyway. The sea by its own restlessness is ringing its own bells. So tolls remorse in a man's heart and no man can stop it.

Our sins are stronger than we are in their power to become habitual. If one who steps from an upper window had only the single act to consider, his problem would be simple. He could step or not as he chose. But when one steps from an upper window he finds himself dealing with a power over which his will has no control. Master of his single act, he is not master of the gravitation that succeeds it. Many a youth blithely plays with sin, supposing that separate deeds—which he may do or refrain from as he will—make up the problem. Soon or late he finds that he is dealing with moral laws, built into the structure of the universe as gravitation is—laws which he did not create and whose operation he cannot control. By them with terrific certainty thoughts grow to deeds, deeds to habits, habits to character, character to destiny.

At the beginning sin always comes disguised as liberty. Its lure is the seductive freedom which it promises from the trammels of conscience and the authority of law. But every man who ever yet accepted sin's offer of a free, unfettered life, discovered the cheat. Free to do the evil thing, to indulge the baser moods—so men begin, but they end not free to stop, bound as slaves to the thing that they were free to do. They have been at liberty to play with a cuttle-fish, and now that the first long arm with its suckers grasps them, and the second arm is waving near, they are not at liberty to get away.

Our sins are mightier than we are in their power to make us tempt our fellows. When we picture our sinfulness, even to ourselves, we naturally represent our lives assailed by the allurements of evil and passively surrendering. We are the tempted; we pity ourselves because the outward pressure was too strong for the inward braces. We forget that in sin we are not simply the passive subjects of temptation; sin always makes us active tempters of our fellows. No drug fiend ever is content until he wins a comrade in his vice; a thief would have his friends steal, too; a gossip is not satisfied until other lips are tearing reputations into shreds; and vindictiveness is happiest when other hearts as well are lighted with lurid tempers. Sin always is contagious as disease is; the tempted becomes tempter on the instant that he falls. Peter weak, lures Jesus to his weakness, and the Master recognizes the active quality of his disciple's sin; "Get thee behind me, Satan!" (Matt. 16:23). Sin satanizes men and sends them out to seduce their fellows. When, therefore, a sensitive man repents of his evil, he abhors himself—not mildly as a victim, but profoundly as a victimizer. He repents of the way he has played Satan to others, sometimes deliberately, sometimes by the unconscious influence of an unworthy spirit. He remembers the times when his words have poisoned the atmosphere which others breathed, when his tempers have conjured up evil spirits in other hearts, when his attitude has made wrongdoing easy for his friends and family, and well-doing hard. And his desperate helplessness in the face of sin is made most evident when he recalls the irrecoverable injury which lives have suffered and are suffering, hurt, perhaps ruined, by his evil.

Our sins are mightier than we are in their power to bring their natural consequences upon other lives. The landlord, of whom President Hyde has told, who without disinfection rented to a new family an apartment where a perilous disease had been, is typical of every evil-doer. When the only child of the incoming family fell sick of the disease and died, and the landlord was faced with his guilt, he pleaded his unwillingness to spend the money which the disinfection would have cost. He denied his Lord for ten dollars. Let the law punish him as it can, the crux of his moral problem lies in the fact that however much he may be sorry now, he never can bear all the consequences of his sin. Somewhere there is a childless home bearing part of the result of his iniquity. One who had done a deed like that might well crave death and oblivion. But everyone who ever sinned is in that estate. No man ever succeeded in building around his evil a wall high and thick enough to contain all evil's consequences. They always flow over and seep through; they fall in cruel disaster on those who love us best. One never estimates his sin aright until he sees that no man ever bears all the results of his own evil. Always our sins nail somebody else to a cross; they even "crucify ... the Son of God afresh" (Heb. 6:6).

Such is the meaning of the peril against whose background the New Testament believers saw the luminous figure of the Savior. Sin brings men into the debt of a great guilt which they cannot pay and into the bondage of tyrannous habits which they cannot break; it makes men tempting satans to their fellows, and it hurls its results like vitriol across the faces of their family and friends. And when one looks on the lamentable evils of the world at large, its sad inequities, its furious wars, he sees no need to deal delicately with sin or to speak of it in apologetic tones. Sin is, as the New Testament saw it, the central problem of mankind. If anyone has ever come with the supreme contribution to its conquest, the face of the world may well be turned toward him today. In the Christian's faith, such a Savior has come. For if the visitor from Mars who so often has been imagined coming to earth, should come again, and amazed at the churches built, the anthems sung, the service wrought in Jesus' name, should curiously inquire what this character had done to awaken such response, we should have to answer: Jesus of Nazareth made no direct contribution to science or art or government or law—with none of these important realms did he concern himself. Only one thing he did: he made the indispensable contribution to man's fight for great character against sin. And because that is man's crucial problem, all science, art, government, and law are under an unpayable indebtedness to him. Because that is man's innermost need, his birthday has become the hinge of history, until one cannot write a letter to his friend without dating his familiar act from the advent of him who came to save us in our struggle for godliness against evil.
