22 Sermon Illustrations on Conscience And Sin

22 illustrations

Conscience in Christian preaching is depicted as the inner witness of God's law, sensitively alerting believers to sin and moral failure (Romans 2:15). It serves as a moral compass and a record of deeds, often portrayed as a king or inward registrar whose unrest reflects guilt and calls for repentance (Hebrews 10:22). Illustrations use images of judgment, inner turmoil, and the hardening or silencing of conscience to emphasize its role in spiritual accountability.

Conscience Must Be Tested

A conscience must be tested by Christian principles, not just personal feelings or appearances.

Not every coin that bears the exact stamp is a genuine coin. Very often, the counterfeit, the base and worthless coin, bears the right stamp also. It isn't the impression that matters so much as the nature of the metal. Many an action that bears the impression of a good conscience is condemned before God as perilous, injurious, and destructive in its issues. The coin must be tested on the touchstone to discover if it rings true. Conscience must be tested on the touchstone of Christian principle and the Spirit of the Master. It is not enough to say, "It seems right to me." We must ask how does this action, this line of conduct, ring on the touchstone of Christian principle? Not what we think but what Christ thinks, what the Master thinks, matters most.

Unjust Balances

A biased heart leads to false judgments, valuing temporary gain over eternal realities.

"In a pair of scales, though the weights be equal, yet if the scales be not equal there may be wrong done: so, though the arguments used be powerful, yet, if the heart be biassed by unhallowed affections, the scale will not be turned according to truth and righteousness." Many instances of this false weighing may be quoted. Eternal realities appear to be mere trifles when the heart is hot after some engrossing pleasure. The most fallacious estimates are made under the influence of corrupt desires. Like a judge that has been bribed, the understanding gives a false verdict. In one scale lies eternity with endless joy or bliss, and in the other lies a passing gain of gold or honour. The comparison needs no studying, it is as a ton to an ounce, and yet the balances are so false that the ounce is declared to have greater weight than the ton. God hateth unjust balances, and we may wisely do the same when we see how souls are ruined by the insane trickery with which a man cheats himself out of his own soul. O Lord of truth, teach my conscience the law of truth, for Jesus' sake. Hold my hand while I hold the scales, and let me weigh all things in the balances of the sanctuary.

The Inward Registrar

Revelation 20:12

Conscience records all sins and will testify at the final judgment.

"Tf conscience speaketh not, it writeth; for it is not only a witness, but a register, and a book of record: 'The sin of Judah is written with a pen of iron, and the point of a diamond': Jer. xvii. 1. We know not what conscience writeth, being occupied and taken up with carnal vanities, but we shall know hereafter, when the books are opened: Rev. xx. 12. Conscience keepeth a diary, and sets down everything. This book, though it be in the sinner's keeping, cannot be razed and blotted out. Well, then, a sleepy conscience will not always sleep; If we suffer it not to awaken here, it will awaken in hell; for the present it sleepeth in many, in regard of motion, check, or smiting, but not in regard of notice and observation." Let those who forget their sins take note of this. There is a chiel within you taking notes, and he will publish all where all will hear it. Never say, "nobody will see me," for you will see yourself, and your conscience will turn king's evidence against you. What a volume Mr. Recorder Conscience has written already! How many blotted pages he has in store, to be produced upon my trial. O thou who alone canst erase this dreadful handwriting, look on me in mercy, as I now look on thee by faith.

The Prick Of A Pin And A Heavy Blow

A tender conscience is a precious grace; hardening through sin is spiritually dangerous.

"The prick of a pin maketh a man start, but a heavy blow stunneth him. David, when he cut off the lap of Saul's garment, his heart smote him, but when he fell into adultery and blood, he was like one in a swoon." Thus it is that a slight departure from right will startle the unsophisticated conscience, while a gross sin may stun it into a horrible insensibility. Much serious thought is suggested by this most striking simile. Among other things it teaches us to dread a benumbed or swooning conscience, for it may have been brought into that condition by a terrible sin. Better far to be morbidly sensitive, and condemn one's self needlessly, than to be hardened through the deceitfulness of sin. A quick and tender conscience is among the best gifts of grace; let those who have it guard its delicacy with jealous care. Lord, let my conscience be as tender as the apple of my eye. As well-balanced scales are tremulous at the fall of a single grain of dust, so let the minutest sin set me on the move. Never, I beseech Thee, permit me to become heavy with the intoxication caused by a deep draught of evil: "Keep back Thy servant also from presumptuous sins; let them not have dominion over me."

Censure, Cause of

People often judge others' faults while ignoring their own conscience and sins.

That divine Spaniard, in his pleasant but useful fiction of the Life of Gusman, makes his rogue discourse of the unconscionableness of the Genoese, and their prying into and censuring of other men's dives; that, when they are young and go first to school, they play away and lose their consciences, which their master finding, he lays them up carefully in a chest. But because he hath the keeping of so many, and they mixed one with another, he gives to his scholars, when they go away, such consciences as come first to hand; which they take to be their own, but are, indeed, somebody's else: whence it comes to pass, that, no man bearing his own conscience in his own bosom, every man looks and prys into that of another man's. The moral is true. There is hardly a man that is not curious in other men's faults, blind in his own, partial to himself, never without matter against others, still complaining of the badness of the times, the decay of trade, the ripeness of sin, but will not be persuaded that he is in any way the occasion of the same. Spencer.

Conscience, Emblem of a Troubled

A sensitive conscience reacts strongly even to the smallest disturbances, showing inner unrest.

There is a species of poplar whose leaves are often rustled by a breeze too faint to stir the foliage of other trees. Noticing the fact one day, when there was scarce a breath of air, Gotthold thought with himself, "This tree is the emblem of a man with a wounded and uneasy conscience, which takes alarm at the most trifling cause, and agitates him to such a pitch, that he knows not whither to fly."

Conscience, an Evil

An evil conscience causes continual unrest and fear until one finds peace in Christ.

An ill conscience is no comfortable companion to carry with thee. An ill conscience is like a thorn in the flesh. A thorn in the hedge may scratch you as you pass by it; but a thorn in the flesh rankles with you wherever you go: and the conscience, the ill conscience, the conscience that is ill at ease, it makes you ill at ease. You cannot have peace so long as you have an evil conscience, so long as there is that continual monition flashing across your mind: "Judgment cometh, death cometh: am I ready?" Many a time when you go to your worldly scenes of pleasure, this conscience, like the finger-writing on the wall of the palace of the King of Babylon, alarms and frightens you. You tell nobody about it. Strange thoughts strike across your mind. You have no rest. Can a man rest on a pillow of thorns? Can a man rest with the heartache? Can a man rest with his soul disturbed with the horrors of guilt? I tell thee there is no rest to thee till thou comest to Christ. He alone can calm a conscience. S. Coley.

Conscience, Guilty

A guilty conscience exposes hidden sin and leads to confession and justice.

According to fable, Ibycus was a poet, going to compete for the prizes at the Isthmian games. As he passed through a grove in his way, he was met by two robbers, and slain. A flock of cranes were flying overhead. With none else to hear, as he fell he cried, "Take up my case, ye cranes!" His body was found, and his fate greatly lamented by all Greece. Thousands on thousands were gathered at the games. The Furies were there represented, clad in black, with writhing serpents curling around their brows. The blood curdled while they loudly sang, "Woe, woe, to him who has done the deed of secret murder! We, the fearful family of night, fasten ourselves upon his whole being. No pity checks our course: still on and on to the end of life, we give him no peace, no rest." This and more they sang, while every heart trembled with undefined terror. At that moment, a cry burst from one of the upper benches. "Look, look, comrade! yonder are the cranes of Ibycus," as a flock of cranes appeared above the theatre. A guilty conscience revealed the murderers. They were arrested, confessed the deed, and the Furies were avenged.

Conscience

Repeated sin hardens the conscience, making it insensitive to guilt and warning.

CONSCIENCE, Hardening the Look but upon a youth when he comes first to be an apprentice to some artificer or handicraft trade, his hand is tender, and no sooner is he set to work than it blisters, so he is much pained thereby; but when he hath continued some time at work, then his hand hardens, and he goes on without any grievance at all. It is just thus with a sinner; before he is accustomed to an evil way, conscience is tender and full of remorse: but a continued custom, and making a trade of sin, makes the conscience to be hard and brawny, able to feel nothing. As it is in a smith's forge, a dog that comes newly in cannot endure the fiery sparks to fly about his ears, but, being once used to it, he sleeps securely; so let wicked men be long used to the Devil's work-house, to be slaves and vassals to sin, the sparks of hell-fire may fly about them, and the fire of hell flash upon their souls, yet never trouble them, never disturb them at all: and all this ariseth from a continued custom in the course of evil. Spencer.

Conscience

Suppressing conscience does not remove God's holiness or His coming judgment.

You may dim the surface of the glass, so that it shall no longer be painfully bright, like a little sun lying on the ground; but your puny operation does not extinguish the great light that glows in heaven. Thus to trample conscience in the wire, so that it shall no longer reflect God's holiness, does not discharge holiness from the character of God. He will come to judge the world, although the world madly silence the witness who tells of his coming. Dr. Arnot.

Conscience, Horrors of a Guilty

A guilty conscience causes constant fear and suspicion due to remembered sins.

Philo Judæus telleth, that Flaccus played all the parts of cruelty that he could devise against the Jews, for their religion's sake; but afterwards, when the doom of Caligula fell upon him, and he was banished to Andros, an island near Greece, he was so tormented with the memory of his bloody iniquities, and a fear of suffering for them, that, if he saw any man walking softly near to him, he would say to himself, "This man is devising to work my destruction:" if he saw any go hastily "Surely it is not for nothing: he maketh speed to kill me." If any man spake him fair, he suspected that he would cozen him, and sought to entrap him; if any talked roughly to him, then he thought that he contemned him. Thus his sin did lie upon him, and ever remind him that some vengeance was to follow. Spencer.

Conscience, Indestructibility of

Conscience is never destroyed and remains a source of torment for the lost.

Conscience, like every other faculty of the soul, is undeveloped in the infant, and very imperfectly developed in the savage; and moreover, after a long habit of inattention to its voice, and violation of its law, the individual sinner is often judicially given up to carnal indifference; his conscience for a time lying latent. Yet it is certain that it is never destroyed. 1. From the fact that it is often aroused to the agonies of remorse. 2. From the fact that this remorse or accusing conscience constitutes the essential torment of lost souls and devils. This is the worm that never dieth. Otherwise, their punishment would lose its moral character. A. A. Hodge.

Conscience, a King

Conscience is God's king in the heart that cannot be permanently silenced or dethroned.

Conscience is God's king, that he puts in a man's breast; and conscience ought to reign. You may get up a civil war to fight against conscience; but you cannot kill the king. You may dethrone him for a while; but he struggles and fights for the mastery. S. Coley.

Conscience, Wakeful

Conscience never sleeps in observation and will reveal hidden sins at judgment.

Though in many men conscience sleep in regard to motion, yet it never sleeps in regard to observation and notice. It may be hard and scared, it can never be blind. Like letters written with the juice of lemon, that which is written upon it, though seemingly invisible and illegible, when brought before the fire of God's judgment, shall come forth clear and expressive.

— M. Cash

Privileges, Misimproved

Rejecting God's light leads to distress and regret at death.

It is related of Seine, the chief of one of the South-Sea Islands, who had offered no small amount of opposition to the introduction of Christianity, that, during a sickness which terminated in his death, he manifested more mental distress than is usually seen in a heathen. He often expressed a wish that he had died ten years before. And why? The light of life and love had been shining around him; but he had opposed its entrance into his heart, and its power over his people. And now, having loved darkness, in darkness of soul, stung by an upbraiding conscience, he must die. Gill.

The Jeweller And His Servant

A murderer’s guilt and hidden sin are eventually exposed despite outward success.

A jeweller, a man of good character, and considerable wealth, having occasion, in the way of business, to travel some distance from his abode, took along with him a servant: he had with him some of his best jewels, and a large sum of money, to which his servant was likewise privy. The master having occasion to dismount on the road, the servant watched his opportunity, took a pistol from his master's saddle, and shot him dead on the spot; then, rifling him of his jewels and money, and hanging a large stone to his neck, he threw him into the nearest canal. With his booty he made off to a distant part of the country, where he had reason to believe that neither he nor his master were known. There he began to trade, in a very low way at first, that his obscurity might screen him from observation; and in the course of many years seemed to rise up, by the natural progress of business, into wealth and consideration; so that his good fortune appeared at once the effect of industry and the reward of virtue. Of these he counterfeited the appearance so well, that he grew into great credit, married into a good family, and, by laying out his hidden stores discreetly, as he saw occasion, and joining to all a universal affability, he was at length admitted to a share of the government of the town, and rose from one post to another, till at last he was chosen chief magistrate. In this office he maintained a fair character, and continued to fill it with no small applause, both as governor and judge; till one day, as he sat on the bench with some of his brethren, a criminal was brought before him who was accused of murdering his master. The evidence came out full; the jury brought in their verdict that the prisoner was guilty, and the whole assembly awaited the sentence of the president of the court (which happened to be himself) in great suspense. Meanwhile he appeared to be in unusual disorder and agitation of mind; his color changed often; at length he arose from his seat, and, coming down from the bench, placed himself just by the unfortunate man at the bar, to the no small astonishment of all present. "You see before you," said he, addressing himself to those who had sat on the bench with him, "a striking instance of the just awards of Heaven, for this day, after thirty years' concealment, presents to you a greater criminal than the man just now found guilty." He then made an ample confession of his heinous offence, with all its peculiar aggravations. "Nor can I," continued he, "feel any relief from the agonies of an awakened conscience, but by requiring that justice be forthwith done against me in the most public and solemn manner." We may easily imagine the amazement of all, especially his fellow-judges. They accordingly proceeded upon his confession, to pass sentence upon him, and he died with all the symptoms of a penitent mind.

The Parricide And Her Husband

Long-hidden murder and guilt lead to confession and divine justice after many years.

A man and his wife were executed at Augsburg for a murder, the discovery of which, after a long lapse of time, strongly manifests the impossibility of eluding the all-seeing eye of Providence. The criminal, whose name was Wineze, was originally of Nuremberg, but removed to Augsburg in 1788, where he became a lawyer. In this city he became intimate in the family of M. Glegg, to whose daughter he paid his addresses; but the old gentleman not sanctioning his visits, he met the daughter privately, seduced her, and persuaded her, in order to remove the only obstacle to their union, to administer poison to her father. The horrid plan succeeded; no suspicions were entertained, and their union put him in possession of the old man's wealth. During a period of twenty-one years they lived externally happy, but, in secret, a prey to the greatest remorse. At length, unable to endure any longer the weight of guilt, the wife made confession of the particulars of the atrocious crime which she had been prevailed upon to commit. The husband was apprehended, and both of them received their desert in an ignominious death.

The Sweep And The Watch

A boy resists stealing, valuing conscience over riches, and is rewarded.

A poor chimney-sweeper's boy was employed at the house of a lady of rank to clean the chimney of her chamber. Finding himself on the hearth of the lady's dressing-room, and perceiving no one there, he waited a few moments to take a view of the beautiful things in the apartment. A gold watch, richly set with diamonds, particularly caught his attention, and he could not forbear taking it in his hand. Immediately the wish arose in his mind: "Ah, if thou hadst such a one!" After a pause he said to himself: "But if I take it I shall be a thief. And yet," continued he, "no one sees me. No one? Does not God see me, who is present every where? Should I then be able to say my prayers to him after I had committed this theft? Could I die in peace?" Overcome by these thoughts a cold shivering seized him. "No!" said he, laying down the watch; "I had much rather be poor and keep my good conscience than rich and become a rogue." At these words he hastened back into the chimney.

The countess, who was in the room adjoining, having overheard his soliloquy, sent for him the next morning and thus accosted him: "My little friend, why did you not take the watch yesterday?" The boy fell on his knees, speechless and astonished. "I heard every thing you said," continued her ladyship; "thank God for enabling you to resist this temptation, and be watchful over yourself for the future. From this moment you shall be in my service; I will both maintain and clothe you—nay, more: I will procure you good instruction, that shall ever guard you from the danger of similar temptations." The boy burst into tears; he was anxious to express his gratitude, but he could not. The countess strictly kept her promise, and had the pleasure to see him grow up a pious and intelligent man.

Forswearing A Debt

A man swears falsely to avoid paying a debt, illustrating the sin of perjury and guilt.

At a Justice's Court, held at Mayslick, Kentucky, says an eye-witness, a cause came on to be heard, wherein the sum in dispute was 75 cts. due to the plaintiff, a tavern-keeper for whisky.

Neither party having any testimony to introduce, Mr. S—, one of the justices, for the purpose of obtaining some knowledge of the situation of the claim, permitted the parties to go into a free conversation, on the subject of their dealings.

After considerable affirmation on one side, and denial on the other, the plaintiff told the defendant, if he would swear he had paid for two half pints, he would strike them out of his account; defendant said he would, and asked Mr. S— to administer the oath, but he being conscious from prior confessions of the defendant, that it was impossible it could be so, said to him, I feel a delicacy in doing so, and you had better pay it; it's a trifling sum, I would not take the trouble to swear for it. Something at that moment called the attention of Mr. S— from the subject, and before he again had fixed his eyes on the defendant, he had slept to Mr. Y—, another of the magistrates, in the other corner of the room, and had sworn in the most solemn manner, to the payment of the money, of which he immediately informed Mr. S—.

Until this awful period, the defendant had retained his usual appearance of health and vigor; but, alas! no sooner had he turned about to inform Mr. S— of his successful attempt to commit the horrid crime of perjury, than a death-like paleness was visible on his countenance; the people in the room simultaneously remarked, with astonishment, the change so instantaneously effected in his appearance. Mr. S— himself remarked, when relating the circumstance, that he had the appearance of a man already two days dead. Judgment was entered for fifty cents, and he retired from the scene of his guilt. But wretched, infatuated mortal! he could not retire from conscious guilt. He took neither refreshment nor sleep that night; but appeared restless, (as his wife relates,) and rolled in his bed from side to side, like one bereft of every earthly enjoyment. Morning came; but with it brought no relief to his perturbed bosom. Still taking no food, after breakfast he went to the field, where a number of reapers had met to cut his grain; he gave them some incoherent directions relative to the harvest, and returned to his house. The whole day was spent in thoughtful musings, and apparent agony of mind: and another night was spent like the preceding. In the morning, a short time after he had left his bed, he was seen running upon all-fours through the door-yard, and exclaiming, "John Johnston (the name of the constable who attended the trial) and the Devil are after me." He was picked up by some men who were about the house, and set down on the step of the door. In a few minutes he suddenly started from his seat, and again commenced running upon his hands and feet as before; and exclaiming most awfully, "John Johnston and the Devil are after me." In this manner he made his way into a small field of corn which stood open to the door-yard, and as he ran between the rows of corn, he tore up a number of hills by the roots, and whilst thus engaged, and before he could be reached by his pursuers, in the act of tearing up a cornhill, he suddenly and instantaneously expired.

Perjury

A senator's guilt over perjury leads to insanity, showing conscience's power and sin's consequences.

THE SENATOR'S OATH:— Mr. J. Taygart was elected a Senator from the county of Columbiana to the second General Assembly of the State of Ohio. He appeared and made the necessary oaths, and took his seat. In a few days he became melancholy, which soon progressed to insanity. In his insane ravings he disclosed that he was not thirty years of age when he took the oath of office and his seat; and that his conscience upbraided him with the crime of perjury in taking an oath to support the constitution, and at the 314-316 same moment taking a seat in violation of its provisions. From this insanity he never recovered, and survived its commencement but a few months.

The Pirate Gibbs

A hardened sinner's conscience dulls, allowing greater sin without remorse.

This man, whose name was for many years a terror to commerce with the West Indies and South America, was at last taken captive, tried, condemned, and executed in the city of New-York. He acknowledged before his death that when he committed the first murder and plundered the first ship, his compunctions were severe, conscience was on the track, and made a hell within his bosom. But after he had sailed for years under the black flag, his conscience became so hardened and blunted, that he could rob a vessel and murder all its crew and then lie down and sleep as sweetly at night as an infant in its cradle. His remorse diminished as his crimes increased. So it is generally. If therefore remorse in this life is God's way of punishing crimes, the more they sin the less he punishes them! How absurd!

Bessus And The Birds

Conscience can cause cruelty to others as a response to personal guilt and pain.

Bessus, a native of Polonia, in Greece, being one day seen by his neighbors pulling down some birds' nests, and passionately destroying their young, was severely reproved by them for his ill-nature, and cruelty to those who seemed to court his protection. He replied, that their notes were to him insufferable, as they never ceased twitting him of the murder of his father.
