God’s Knowledge of Sin

Charles Haddon Spurgeon October 19, 1884 Scripture: Psalms 69:5 From: Metropolitan Tabernacle Pulpit Volume 44

God’s Knowledge of Sin


“O God, thou knowest my foolishness; and my sins are not hid from thee.” — Psalm lxix. 5.


IT seems, thou, that the best of men have a measure of foolishness in them, and that, sometimes, that foolishness shows itself. How gentle and tender ought we to be with others who are foolish when we remember how foolish we are ourselves! How sincerely ought we to rejoice in Christ as made of God unto us wisdom, when we see the folly that is bound up in our hearts, and which too often shows itself in our talk and in our acts! Yet while the best of men have folly in them, it is ono of the marks of a good man that he knows it to be folly, and that he is willing to confess his sin before God. “If we say that we have no sin, we deceive ourselves, and the truth is not in us.” If we stand as the Pharisee stood in the temple, and cry, “God, I thank thee, that I am not as other men are,” we shall go home, as the Pharisee did, without the justification which comes from God. It is the truly good man who stands afar off with the publican, and cries, “God be merciful to me a sinner,” and he also shall go to his house “justified rather than the other.”

     There is one solemn thought which deeply impresses the man who is right at heart, but who sees his own foolishness and sin, and mourns it; and that thought is, that God sees it, and sees it more perfectly than he sees it himself. His own sight of it makes him repent, and humble himself; and his knowledge of God’s sight of it helps him to that repentance and humiliation. God sees everything concerning every man; but the most of men care not about God seeing them, they do not give it so much as a passing thought. It is the gracious man, the child of God who, from a broken heart, cries out, “O God, thou knowest my foolishness; and my sins are not hid from thee.” And this it is that makes a Christian man so greatly value the precious blood of Christ, and the perfect righteousness which Jesus Christ has wrought out; albeit that omniscience still perceives sin, yet justice does not perceive it. God knows we are sinners, but he imputes to all believers the righteousness of Christ, and looks upon them as they are in him. He cleanses us in the precious blood of Jesus, so that we are clean in his sight, and “accepted in the Beloved.” What a wonderful atonement is that which hides from God that which cannot be hidden, so that God does not see what, in another sense, he must always see, and forgets what it is impossible for him, in another sense, ever to forget! In a just and judicial way, God casts our sin behind his back, and ceases to see iniquity in his people because they are clean every whit through washing in the—

“Fountain filled with blood,
Drawn from Immanuel’s veins.”

     Now, looking at our text, I am going to call attention to the great truth of the omniscience of God, desiring that each one of us may say from our heart, “O God, thou knowest my foolishness; and my sins are not hid from thee.”

     I. First, concerning God’s knowledge of man’s sin, I remark that IT MUST BE so. I am not going to argue, but just to talk a little to set this truth before you with greater assurance of certainty.

     God must know our foolishness, for, first, he is infinite in knowledge. We cannot conceive of a God whose knowledge is bounded. That condition belongs to the finite, the creature, but not to the Infinite, the Creator, the great First Cause of everything. God knows all the past, and all the present, and all the future. He knows all the things that might have been, and are not. He knows what might have come out of certain germs, and what yet may come, which at the present seems to be far remote. All knowable things must be known to the Most High; the very nature of God implies it; and, hence, he must know my foolishness, for I know something of it myself; he must know much more than I know; and my sins are not hid from him, for they are not altogether hidden from myself. God must know perfectly what I only perceive in part, though that partial perception be terrible to my own heart. Yes, the infinite knowledge of God is an absolute certainty; and, consequently, his knowledge of the folly and sin of every heart is beyond all question.

     Moreover, God is everywhere present. At all times, he is in every place; and, hence, our foolishness and sin must be known to him. If is not merely that you committed a folly or a sin, and that it was reported to God. No, but he was there during the doing of it. What though the blinds were drawn, and the doors were fast closed? Yet HE was there; and all through the sin, he stood by you, and observed your every thought and every movement. There is no darkness that hides from him, nor any other form of screen that can be used to shut out the glances of the eye of the Eternal. He does not see from a distance, but he is on the spot. You cannot conceive of a place where God is not, for he fills all space. There could no more be a boundary to his existence than to his knowledge; and, hence, we are sure that our text is true, “O God, thou knowest my foolishness; and my sins are not hid from thee.”

     Moreover, God is also everywhere perceiving. He is never a blind God, nor a blind-folded God. His knowledge is never, even for a moment, stayed, and rendered intermittent; but, as his presence is on the highest hill and in the deepest cavern, far away on the wild sea or in the plain where the foot of man has scarcely made a track, so, in that presence, there is a constant sight, an unfailing observation at all times. You would not, I hope, reduce God to the level of one who has eyes, and sees not. “He that planted the ear, shall he not hear? He that formed the eye, shall he not see?” The fact that eyesight and hearing come from him proves how abundantly he possesses those faculties himself. He sees and he hears in every place, and there was never anything done of man without his knowledge. The secret murder, the silent plot where everybody had sworn an oath of secrecy, all was known to God. There was never a thought in a human mind, although the man had not uttered it in words even to himself, but what the Lord perceived it. Does not this make the fact certain that he knows my foolishness, and that my sins are not hidden from him? Infinite in knowledge, everywhere present, and everywhere perceiving everything, he must know my foolishness and my sin. Dr. Watts forcibly expresses this idea in his hymn on God’s omnipresence, —

“In all my vast concerns with thee,
In vain my soul would try
To shun thy presence, Lord, or flee
The notice of thine eye.

“Thy all-surrounding sight surveys
My rising and my rest;
My public walks, my private ways,
And secrets of my breast.

“If wing’d with beams of morning light,
I fly beyond the west;
Thy hand, which must support my flight,
Would soon betray my rest.

“If o’er my sins I think to draw
The curtains of the night;
Those flaming eyes that guard thy law
Would turn the shades to light.

“The beams of noon, the midnight hour,
Are both alike to thee:
Oh, may I ne’er provoke that power
From which I cannot flee!”

     Beside that, God is ever reading the heart. We have heard a good deal about thought-reading; I hope that the most of you will never be gifted in that direction, for such a power would make it very unpleasant for many. One said that he wished that he had a window in his bosom, that everybody might read his thoughts. I think that, if he were at all a sensible man, he would want to pull the blind down before long. There is something which, now and again, crosses the purest mind which he would not wish another to perceive; and he who watches his thoughts with an exemplary vigilance will sometimes be off his guard, and tolerate an imagination which he would not wish to pollute any other person’s mind. But though we cannot read each other’s hearts, God can read them. There is no possibility of lying unto the Lord so as to deceive him. He reads the hypocrite when he puts on his fine vestments, and prays his prayer in the most devout style, and even when he gets into his closet, and bows before his God only after a formal manner. We may have performed what looked like a holy deed, we may have sung a solemn psalm, we may have appeared unto our fellow-men to be among the excellent of the earth; but if it be not really so, no one can hide himself in secret, or conceal the deceit of his spirit in the dark place from the eyes of the Most High. Though thou shouldst climb to the top of Carmel in the pride of thine heart, or go down with Jonah to the bottoms of the mountains in thy deceit, yet shall he find thee out, and strip thee, and unmask thee, and set thee in the sunlight to be despised of men and all intelligent beings, as they also shall see thy falsity. O beloved, God must have seen my foolishness, and my sins cannot be hid from him, since he reads the secrets of the heart, and the tortuous passages of the soul are easily threaded by his unerring wisdom!

     We are clear also that he knows our foolishness and our sin because he knows what is yet to be. To know what men have already done, is a light matter compared with knowing what men will yet do. There are black crimes which are recorded by Moses in Scripture which Moses never could have known if God had not first seen them and then communicated the knowledge of them to him. There are many incidents mentioned in the Pentateuch which could only have come to the knowledge of Moses through the revelation of the Spirit of God, and therefore God himself knew all about those events; but, throughout the prophecies, there are intimations of the sins of men that would yet be committed, and more especially that sin of sins, the crucifixion of the Lord Jesus Christ ; that crime of crimes is described in all its dreadful details. Now, if God saw all that, and recorded it by the agency of his servants centuries before it happened, there can be no hope that anything which has ever occurred has escaped the observation of the Most High. You are all books, and every page is open to the eye of the great Reader, who reads you from the first letter to the last. There is nothing which any man here can possibly conceal from God. Men love what they call secrets, yet are there no such things in very truth where God is concerned, for he observes everything. It matters not what it may be, minute or majestic, malevolent or benevolent, a curse or a blessing, it all passes before that eye which never wearies or sleeps, or suffers anything to escape its notice. It is so, it must be so; if God be God, he knows my foolishness, and my sins are not hid from him.

     II. Now let us just turn the current of our thought while I ask, concerning God’s knowledge of man’s sin, AFTER WHAT FASHION IS IT? If God knows, in what particular way does he know?

     The answer is, that it is complete knowledge; the Lord knows us altogether. I must confess that I cower down beneath that thought. That the Lord should know my public service, is sufficiently awestriking; but that he should know my private thoughts, ah! this sinks me into the very dust! The Lord knows not only the action, but the motive of the action; all the thoughts that went with my action, all the pride and self-seeking that came after it, and spoiled it, when else it might have been praiseworthy. “Every way of a man is right in his own eyes: but the Lord pondereth the hearts.” The word “pondereth” means that he weighs us, he takes the specific gravity of our actions. They may cover a great surface, yet there may be no real substance in them at all; but the Lord weighs them as goldsmiths weigh the metal that is subjected to their test. He takes care not to be deceived by anything that is apparent to our fellow-men. “The fining pot is for silver, and the furnace for gold: but the Lord trieth the hearts.” There is nothing hidden from God’s eye, every separate part of us is open to his perpetual inspection; think of that. God’s knowledge is complete, and baffles all evasion.

     It is also the knowledge of a holy Being. You perhaps know some people who see all they can, yet do not see all that can be seen. It is with them as it was with the lady who said to Turner, as she looked upon one of his notable paintings, “Mr. Turner, I have never seen anything like that.” “No,” replied the artist, “I don’t suppose that you have seen it; don’t you wish that you could?” So, when God looks at a man’s life, he sees infinitely more in it than the man ever saw in it himself, or than all his fellow-creatures have seen. The keen eye of envy and of malice will detect a fault, if fault there be; but keener is the eye of perfect holiness. The Lord’s eyes are as a flame of lire; being himself essential truth, he truly discovers everything that is within us, and makes no mistakes. When we are dealing with God, mistakes on his part are quite out of the question. He knows us after the manner of a perfectly holy Being; and many a thing, that looked white to us, is absolutely black to God. His eyes can see according to the clear white light of heaven; but you and I can only see in some one ray of faint light; we see not as God seeth. We shall one day be holy as he is holy, and we shall then look upon the affairs of this life in a strangely different light from that in which we look upon them now; and when once we get to heaven, we shall realize how foolish we were to form the judgments that we did form while we were here. “Now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.” Think of this, dear friends; the eyes that see you are the eyes of a perfectly holy God, who therefore more readily discovers your shortcomings and your sins than all the eyes of men could do.

     Reflect, again, that God knows us with an abiding knowledge. It is a great mercy that time brings with it an assuagement of our sorrows by the oblivion in which it steeps us. You lost your mother, and you could not have lived a month suffering the pangs that you felt in the moment that you realized your loss. All your losses are the same as they were when they first befell you; but they do not eat into your spirit with that terrible force which was in them at the first, for time has taken off their edge. It is so with sin; the first time that the youth told a lie, he could not sleep; but that first lie was forty years ago, and he is almost sorry that I have brought it to his recollection now. After a while, time covers hp the remembrance of sin, and we think that God has covered it up; but every sin, even of fifty years ago, is present to God’s eye just as if you were committing it at this moment; and your whole life does not stand out to him as the dim past and the bright present, it is all present to him. As when a man looks on a map, and the whole of the country is before him, so does God look down upon our life as it is spread out for his inspection, and he sees it all at once. Up from the graves of forgetfulness where you have buried them, your sins perpetually rise, and confront the judgment-seat of God. Think seriously of this matter, for it is after this manner that God knows our foolishness, and that our sins are not hid from him.

     The Lord has an eternal knowledge of our sins; he never will forget them. If they are not washed away by the blood of Christ, he never can forget or cease to be angry because of them. He has written the record of man’s sin in a book; he means it, therefore, to abide. He says, “Is not this laid up in store with me, and sealed up among my treasures?” It is as if he had put men’s sin by, to be called as a damning witness against them in that great day when every action and word and thought shall pass before the judgment-seat. I do not know how this thought makes you feel, but it makes me tremble while I speak of it.

     For, further, all our sins are known to him who is to be our Judge. There will be no need of witnesses in that last dread day, for the Judge knows all about us. There will be no need to call this one and that to bear testimony as to our sin, for the Judge saw it, and heard it, and he has never forgotten it, nor does his memory fail him as to any of the details. He will flash that eternal light of his into the conscience of the criminal, and write upon the tablet of his heart the revived memory of all that ho had forgotten; and there cannot be a more terrible hell for a man than to be in the grasp of his memory and of his conscience in the last great day. Yet so it will be, and I beg each unconverted man to recollect that his foolishness and his sin are known to him to whom he must give an account at the day of judgment.

     One thought more might, perhaps, tend to impress some who have not yet felt the force of this truth; and that is, that this knowledge will be published. If God knows about our sin, it is tantamount to everybody knowing about it. “Oh!” says someone, “I trust it will not be so; I hope that nobody knows of that dark deed of mine.” I tell you, sir, everybody shall know of it, “for there is nothing covered, that shall not be revealed; neither hid, that shall not be known.” There shall come a day, the day for which all other days were made, when the books shall be opened, and every man shall give an account of the deeds done in the body, whether they have been good or whether they have been evil ; and, further, our Saviour said, “ That every idle word that men shall speak, they shall give account thereof in the day of judgment.” Can we bear to have it all known? Yet known it shall be, written as athwart the sky, when those we have deceived and deluded shall discover what we were, and we shall wake up to everlasting shame and contempt unless we find shelter in the atoning sacrifice, and be washed in the precious blood of Christ. If I could speak of these solemn truths as I ought to speak of them, they would move your hearts; I pray God that they may.

     III. And now, thirdly, WHAT THEN? If God sees everything, and sees it in the fashion I have tried to describe, what then?

     Why, first, how frivolous must those be who never think about it! A man is about to commit a crime; but his child is present, so he hesitates; or somebody looks in at the window, and he cannot do the wrong he intended. How is it that men will tremble under the eye of a child, and almost at the presence of a dog, and yet God’s presence is nothing at all to them? A man, about to steal, had taken his child with him to help him secure the booty. lie looked all round, and said, “There is nobody here, boy;” but the lad said, “Father, there is one way you did not look; you did not look up. God can see you.” Just so, men do not look up; and if you tell them that God sees them, of what account is he to them? This is practical atheism, yet men say that they would not have crucified Christ. Sirs, as far as you can, you do kill God, for you put him out of your thoughts, you make nothing of him, and what is that but the crucifixion of God? You despise him so much that his presence has no effect upon you, though the presence of any mortal man would have stopped you from your sin.

     Next, dear brethren, what care this ought to work in us! How diligently we ought to do our work for God, how earnestly we ought to pray, when we know that we always have the great Taskmaster's eye upon us; or, better still, that dear eye that looked in pity upon us, when we were lost and ruined! The eye of the Well-beloved, who gave himself for us, is always fixed upon us. “Fight, my children,” said a Highland chieftain, “fight and conquer; for your chieftain, though he lies here bleeding, has his eye upon you.” And they fought like tigers under their leader’s eye; and thus should Christians fight against sin when the eye of the beloved Captain, who died for them, is always upon them. There must be no sleeping, there must be no “scamping” of our work, as bad workmen do when the master is away. It must be gold, silver, and precious stones that we build with, and every stone must be well laid upon the one great foundation; everything must be done at the very best, because God sees it. You know how the heathen sculptor put it; he was working with his chisel and hammer upon the back part of a statue of which only the front was to be soon. The hinder part was to be built into the wall, so someone said to him, “Why are you toiling so elaborately at that which will be hidden in the wall?” He answered, “The gods can see inside the wall.” The heathen gods could not see, but our God can; and, hence, the secret part of our life is, perhaps, the most important part of it. That which is never meant for the eye of man, but wholly for the eye of God, ought to have a double care exercised in the perfecting of it, that his eye may rest upon it with a sacred complacency, according to his abounding grace and mercy.

     And what holy trembling this ought to put within us! It is often a joy to think that God knows everything; it was a true comfort to Peter when he could say, “Lord, thou knowest all things; thou knowest that I love thee.” It is a great joy, when you are slandered and misrepresented, to be able to say, “Well, God knows the way that I take; and when he has tried me, he will bring me forth as gold. My true record is on high, so I need not fear what the record may be below.” That is a very delightful thought. At the same time, can any among you look forward to that last great day without some trembling? Does it not take all your faith in the atoning blood and in the Divine Substitute to gird up your loins that you may face that day without fear, ay, and even that you may live now in the full conviction that your life is all known to God?

     Just let us think for a minute or two more about this subject, and then I will close. The Lord knows all about us, so that he knows our omissions. I do not know any subject that so much depresses me, humbles me, and lays me in the dust, as the thought of my omissions. It is not what I have done, about which I think so much as of what I have not done. “You have been very useful,” says one. Yes, but might I not have been ten times more useful? “You have been very diligent,” says another. Yes, but might I not somehow have been more diligent? Might I not have done my work in a better spirit? If I had been better, would not my work have been better? If I had borrowed more of my Master’s strength, which I might have had, might I not have accomplished much more? Do you ever feel satisfied with yourself? If so, I would advise you to fling that satisfaction out of the window, as Jehu said of the painted Jezebel, “Throw her down.” A sense of satisfaction with yourself will be the death of your progress, and it will prevent your sanctification. Many a man might have been sanctified if he had not thought that he was already sanctified; by that thought he clutched the shadow, and so he lost the substance. Mind that such a thing as that does not happen to you.

     Our Lord knows all the faults of our holy things; — the coldness of our prayers, the wandering of our thoughts, the scantiness of our alms-giving, and the hardness of our hearts, so that they do not go in generous tenderness with the gift we feel bound to bestow. Our sermons, our Bible-readings, our Sunday-school teachings, — the Lord sees the faults of them; while our friends often see the excellences of them. I have had many abusive letters at different periods of my life, but specially in the early part of my career in London I think that I had as much abuse as ever fell to the lot of anybody ; but, as I read letter after letter, I said to myself, “ O foolish writers, if you knew me better, you could say sharper things than these, that would sting me much more ; but, happily, you have never been able to lay your hands on the truth yet. You have had to tell a lie in order to abuse me, and that does not hurt me a bit. If you had known me as God does, you might have had something to say which would have caused me great sorrow.” If men could read the secrets of your soul, sincere though you have tried to be, they would see such failures, and slips, and errors, that you would not dare to set your holiest things in the light of day; yet the Lord knows the sins even of your holy things.

     Then the Lord also knows our falsities. That is a very tender point. “We do not lie,” we say; but is there any man among us who is perfectly true? When you prayed, did you not say a little more than you had ever attained in your own experience? Or you were talking about yourself, and you wished to be very sincere and truthful, but you did put just a touch of colour into the picture, did you not? At least, you painted yourself with your finger over your scar; there are not many like Oliver Cromwell, who said, “If you do make a portrait of me, paint me as I am, — warts and all.” You may do that with the warts on your forehead, but I question whether you would like the warts on your character to be seen. “I hate flattery,” says one. Why, you are flattering yourself all the while that you are saying that. “But,” says one, “I do feel that I am humble.” Do you? Then I guess that you are not really so, for he who is humble still laments his pride, and thus shows his humility better than in any other way. But, whatever we are, God sees all our falsities, and there is nothing hidden from him.

     Lastly, the Lord knows— and this is the best thing that he does know about us, — he knows, concerning some of us, that we are clinging to Christ alone. Unless I am utterly deceived, I can truth fully say to the Lord Jesus Christ, —

“Other refuge have I none,
Hangs my helpless soul on thee.”

Cannot you say the same, dear friend? If you can, take heart. Dc not be afraid of God knowing all, but rather say, as we read a little while ago, “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.” Pray with David, “Wash me throughly from mine iniquity, and cleanse me from my sin.” Come and cast yourself upon the omniscience of God, desiring to be cleansed, — spirit, soul, and body, — and made meet to enter where the redeemed and glorified Church adores the Lord for ever without fault before his throne.

     God bless this searching message to every one of you, for his dear Son’s sake! Amen.
