Psalm 139:23



Verse 23. Search me, O God, and know my heart. David is no accomplice with traitors. He has disowned them in set form, and now he appeals to God that he does not harbour a trace of fellowship with them. He will have God himself search him, and search him thoroughly, till every point of his being is known, and read, and understood; for he is sure that even by such an investigation there will be found in him no complicity with wicked men. He challenges the fullest investigation, the innermost search: he had need be a true man who can put himself deliberately into such a crucible. Yet we may each one desire such searching; for it would be a terrible calamity to us for sin to remain in our hearts unknown and undiscovered.

Try me, and know my thoughts. Exercise any and every test upon me. By fire and by water let me be examined. Read not alone the desires of my heart, but the fugitive thoughts of my head. Know with all penetrating knowledge all that is or has been in the chambers of my mind. What a mercy that there is one being who can know us to perfection! He is intimately at home with us. He is graciously inclined towards us, and is willing to bend his omniscience to serve the end of our sanctification. Let us pray as David did, and let us be as honest as he. We cannot hide our sin: salvation lies the other way, in a plain discovery of evil, and an effectual severance from it.



Verse 23. Try me. True faith is precious; it is like gold, it will endure a trial. Presumption is but a counterfeit, and cannot abide to be tried: 1 Peter 1:7 . A true believer fears no trial. He is willing to be tried by God. He is willing to have his faith tried by others, he shuns not the touchstone. He is much in testing himself. He would not take anything upon trust, especially that which is of such moment. He is willing to hear the worst as well as the best. That preaching pleases him best which is most searching and distinguishing: Heb 4:12. He is loath to be deluded with vain hopes. He would not be flattered into a false conceit of his spiritual state. When trials are offered, he complies with the apostle's advice, 2 Corinthians 13:5 . --David Clarkson.

Verse 23. What fearful dilemma have we here? The Holiest changeth not, when he comes a visitant to a human heart. He is the same there that he is in the highest heaven. He cannot look upon sin; and how can a human heart welcome him into its secret chambers? How can the blazing fire welcome the quenching water? It is easy to commit to memory the seemly prayer of an ancient penitent, Search me, O God, and know my heart; try me, and know my thoughts. The dead letters, worn smooth by frequent use, may drop freely from callous lips, leaving no sense of scalding on the conscience; and yet, truth of God though they are, they may be turned into a lie in the act of utterance. The prayer is not true, although it is borrowed from the Bible, if the suppliant invite the All seeing in, and yet would give a thousand worlds, if he had them, to keep him out for ever.

Christ has declared the difficulty, and solved it: "I am the way, the truth, and the life: no man cometh unto the Father, but by me." When the Son has made the sinner free, he is free indeed. The dear child, pardoned and reconciled, loves and longs for the Father's presence. What! is there neither spot nor wrinkle now upon the man, that he dares to challenge inspection by the Omniscient, and to offer his heart as Jehovah's dwelling place? He is not yet so pure; and well he knows it. The groan is bursting yet from his broken heart: "O wretched man that I am! Who shall deliver me from the body of this death?" Many stains defile him yet; but he loathes them now, and longs to be free. The difference between an unconverted and a converted man is not that the one has sins, and the other has none; but that the one takes part with his cherished sins against a dreaded God, and the other takes part with a reconciled God against his hated sins. He is out with his former friends, and in with his former adversary. Conversion is a turning, and it is one turning only; but it produces simultaneously and necessarily two distinct effects. Whereas his face was formerly turned away from God, and toward his own sins; it is now turned away from his own sins, and toward God. This one turning, with its twofold result, is in Christ the Mediator, and through the work of the Spirit.

As long as God is my enemy, I am his. I have no more power to change that condition than the polished surface has to refrain from reflecting the sunshine that falls upon it. It is God's love, from the face of Jesus shining into my dark heart, that makes my heart open to him, and delight to be his dwelling place. The eyes of the just Avenger I cannot endure to be in this place of sin; but the eye of the compassionate Physician I shall gladly admit into this place of disease; for he comes from heaven to earth that he may heal such sin sick souls as mine. When a disciple desires to be searched by the living God, he does not thereby intimate that there are no sins in him to be discovered: he intimates rather that his foes are so many and so lively, that nothing can subdue them except the presence and power of God. --William Arnot (--1875), in "Laws from Heaven for Life on Earth."

Verse 23-24. There are several things worthy of notice in the Psalmist's appeal, in the words before us. First, notice the Psalmist's intrepidity. Here is a man determined to explore the recesses of his own heart. Did Bonaparte, did Nelson, did Wellington, ever propose to do this? Were all the renowned heroes of antiquity present, I would ask them all if they ever had courage to enter into their own hearts. David was a man of courage. When he slew a lion in the way, when he successfully encountered a bear, when he went out to meet the giant Goliath, he gave undoubted proofs of courage; but never did he display such signal intrepidity as when he determined to look into his own heart. If you stood upon some eminence, and saw all the ravenous and venomous creatures that ever lived collected before you, it would not require such courage to combat them as to combat with your own heart. Every sin is a devil, and each may say, "My name is Legion, for we are many." Who knows what it is to face himself? And yet, if we would be saved, this must be done.

Secondly, notice the Psalmist's integrity. He wished to know all his sins, that he might be delivered from them. As every individual must know his sins at some period, a wise man will seek to know them here, because the present is the only time in which to glorify God, by confessing, by renouncing, by overcoming them. One of the attributes of sin is to hide man from himself, to conceal his deformity, to prevent him from forming a just conception of his true condition. It is a solemn fact, that there is not an evil principle in the bosom of the devil himself which does not exist in ours, at the present moment, unless we are fully renewed by the power of the Holy Spirit. That these evil principles do not continually develop themselves, in all their hideous deformity, is entirely owing to the restraining and forbearing mercy of God.

Thirdly, notice the Psalmist's wisdom. He presents his prayer to God himself. God is the only Being in the universe that knows himself -- that peruses himself in his own light. In the same light he sees all other beings; and hence it follows that, if other beings see themselves truly, it must be in the light of God. If the sun were an intelligent being, I would ask him, "How do you see yourself? In your own light?" And he would reply, "Yes." "And how do you see the planets that are continually revolving around you?" "In my own light also, for all the light that is in them is borrowed from me".

You will observe that the Psalmist begins with his principles: his desire is to have these tried by a competent judge, and to have every thing that is evil removed from them. This is an evidence of his wisdom. The heart and its thoughts must be made right, before the actions of the life can be set right. Those who are most eminent for piety are most conversant with God; and, for this reason, they become most conversant with themselves. David says, elsewhere, "Who can understand his errors? Cleanse THOU me from secret faults." And Job says, "If I wash myself with snow water, and make me never so clean, yet shalt THOU plunge me in the ditch, and mine own clothes shall abhor me." When these holy men perused themselves in God's light, they saw their sins of omission and commission, and prayed earnestly to be delivered from all. -- William Howels, 1832.

Verse 23-24. The text is a prayer, and it indicates, as we think, three great facts in regard to the suppliant: the first, that David thoroughly wished to become acquainted with himself; the second, that he felt conscious that God could see through all disguises; and the third, that he desired to discover, in order that by Divine help he might correct, whatsoever was wrong in his conduct.

Now, the first inference which we draw from the text, when considered as indicating the feelings of the petitioner is, that he was thoroughly honest, that it was really his wish to become acquainted with his own heart. And is there, you may say, anything rare or remarkable in this? Indeed we think there is. It would need, we believe, a very high degree of piety to be able to put up with sincerity the prayers of our text. For, will you tell me that it does not often happen, that even whilst men are carrying on a process of self examination, there is a secret wish to remain ignorant of certain points, a desire not to be proved wrong when interest and inclination combine in demanding an opposite verdict? ... In searching into yourselves, you know where the tender points are, and those points you will be apt to avoid, so as not to put yourselves to pain, nor make it evident how much you need the caustic and the knife. Indeed, we may be sure that we state nothing but what experience will prove, when we declare it a high attainment in religion to be ready to know how bad we are ... And this had evidently been reached by the Psalmist, for he pleads very earnestly with God that he would leave no recess of his spirit unexplored, that he would bring the heart and all its thoughts, the life and all its ways, under a most searching examination, so that no form and no degree of evil might fail to be detected. -- Henry Melvill.

Verse 23-24. Self examination is not the simple thing which, at first sight, it might appear. No Christian who has ever really practised it has found it easy. Is there any exercise of the soul which any one of us has found so unsatisfactory, so almost impossible, as self examination? The fact is this, that the heart is so exceedingly complicated and intricate, and it is so very near the eye which has to investigate it, and both it and the eye are so restless and so shifting, that its deep anatomy baffles our research. Just a few things, here and there, broad and open, and floating upon the surface, a man discovers; but there are chambers receding within chambers, in that deepest of all deep things, a sinner's heart, which no mere human investigation ever will reach, ... it is the prerogative of God alone to "search" the human heart.

To the child of God -- the most intimate with himself in all the earth -- I do not hesitate to say -- "There are sins latent at this moment in you, of which you have no idea; but it only requires a larger measure of spiritual illumination to impress and unfold them. You have no idea of the wickedness that is now in you." But while I say this, let every Christian count well the cost before he ventures on the bold act of asking God to "search" him. For be sure of this, if you do really and earnestly ask God to "search" you, he will do it. And he will search you most searchingly; and if you ask him to "try" you, he will try you, -- and the trial will be no light matter!

I am persuaded that we often little calculate what we are doing -- what we are asking God to do -- when we implore him to give us some spiritual attainment, some growth in grace, some increase in holiness, or peace. To all these things there is a condition, and that condition lies in a discipline, and that discipline is generally proportionate to the strength and the measure of the gift that we ask.

I do not know what may have been the state of the Psalmist at the period when he wrote this Psalm; but I should think either one of Saul's most cruel persecutions, or the rebellion of his son Absalom, followed quick upon the traces of that prayer, Search me, O God, and know my heart: try me, and know my thoughts, etc.

Still, whatever his attainment, every child of God will desire, at any sacrifice, to know his own exact state before God; for, as he desires in all things to have a mind conformed to the mind of God, so he is especially jealous lest he should, by any means, be taking a different view, or estimate, of his own soul from that which God sees it. -- Condensed from James Vaughan.

Verse 23-24. Hypocrisy at the fashionable end of the town is very different from hypocrisy in the city. The modish hypocrite endeavours to appear more vicious than he really is, the other kind of hypocrite more virtuous. The former is afraid of everything that has the show of religion in it, and would be thought engaged in many criminal gallantries and amours which he is not guilty of. The latter assumes a face of sanctity, and covers a multitude of vices under a seeming religious deportment.

But there is another kind of hypocrisy, which differs from both of these: I mean that hypocrisy by which a man does not only deceive the world, but very often imposes on himself; that hypocrisy which conceals his own heart from him, and makes him believe he is more virtuous than he really is, and either not attend to his vices, or mistake even his vices for virtues. It is this fatal hypocrisy and self deceit which is taken notice of in those words, "Who can understand his errors? cleanse thou me from secret faults."

These two kinds of hypocrisy, namely, that of deceiving the world, and that of imposing on ourselves, are touched with wonderful beauty in the hundred and thirty-ninth Psalm. The folly of the first kind of hypocrisy is there set forth by reflections on God's omniscience and omnipresence, which are celebrated in as noble strains of poetry as any other I ever met with, either sacred or profane. The other kind of hypocrisy, whereby a man deceives himself, is intimated in the two last verses, where the Psalmist addresses himself to the great Searcher of hearts in that emphatic petition; "Try me, O God, and seek the ground of my heart: prove me, and examine my thoughts. Look well if there be any way of wickedness in me, and lead me in the way everlasting." --Joseph Addison (1672-1719), in "The Spectator."

Verse 23-24. How beautiful is the humility of David! He cannot speak of the wicked but in terms of righteous indignation; he cannot but hate the haters of his God; yet, he seems immediately to recollect, and to check himself -- "Try me, O Lord, and seek the ground of my heart." Precisely in the same spirit of inward humility and self recollection, Abraham, when pleading before God in prayer for guilty depraved Sodom, fails not to speak of himself, as being dust and ashes: Genesis 18:27 . --James Ford, 1871.

Verse 23-24. Why did David pray thus to God, Search me, O God, and know my heart, having said before, in the first verse, "Thou hast searched me, and known me"? Seeing David knew that God had searched him, what needed he to pray that God would search him? why did he beg God to do that which he had done already? The answer is at hand. David was a diligent self searcher, and therefore he was so willing to be searched, yea, he delighted to be searched by God; and that not (as was said) because himself had done it already, but also because he knew God could do it better. He knew by his own search that he did not live in any way of wickedness against his knowledge, and yet he knew there might be some way of wickedness in him that he knew not of. And therefore he doth not only say, "Search me, O God, and know my thoughts"; but he adds, "See if there be any wicked way (or any way of pain and grief) in me"; (the same word signifies both, because wicked ways lead in the end to pain and grief); "and lead me in the way everlasting." As if he had said, Lord, I have searched myself, and can see no wicked way in me; but, Lord, thy sight is infinitely clearer than mine, and if thou wilt but search me thou mayest see some wicked way in me which I could not see, and I would fain see and know the worst of myself, that I might amend and grow better; therefore, Lord, if there be any such way in me, cause me to know it also. O take that way out of me, and take me out of that way; "lead me in the way everlasting." David had tried himself, and he would again be tried by God, that he, being better tried, might become yet better. He found himself gold upon his own trial and yet he feared there might be some dross in him that he had not found; and now he would be retried that he might come forth purest gold. Pure gold fears neither the furnace nor the fire, neither the test nor the touchstone; nor is weighty gold afraid of the balance. He that is weight will be weight, how often soever he is weighed; he that is gold will be gold, how often soever he is tried, and the oftener he is tried the purer gold he will be; what he is he will be, and he would be better than he is. -- Joseph Caryl.



Verse 23-24. The language,

  1. Of self examination.

    1. As in the sight of God.
    2. With a desire for the help of God: Psalms 139:23 . Look me through, and through, and tell me what thou thinkest of me.
  2. Of self renunciation: "See if", etc. ( Psalms 139:24 ); any sin unpardoned, any evil disposition unsubdued, any evil habit unrestrained, that I may renounce it.
  3. Of self dedication: "Lead me", etc.: a submission entirely to divine guidance in the future.
