Psalm 66:18



Verse 18. If I regard iniquity in my heart. If, having seen it to be there, I continue to gaze upon it without aversion; if I cherish it, have a side glance of love toward it, excuse it, and palliate it;

The Lord will not hear me. How can he? Can I desire him to connive at my sin, and accept me while I wilfully cling to any evil way? Nothing hinders prayer like iniquity harboured in the breast; as with Cain, so with us, sin lieth at the door, and blocks the passage. If thou listen to the devil, God will not listen to thee. If you refuse to hear God's commands, he will surely refuse to hear thy prayers. An imperfect petition God will hear for Christ's sake, but not one which is wilfully miswritten by a traitor's hand. For God to accept our devotions, while we are delighting in sin, would be to make himself the God of hypocrites, which is a fitter name for Satan than for the Holy One of Israel.



Verse 18. If I regard iniquity in my heart, the Lord will not hear me. The very supposition that "if he regarded iniquity in his heart, the Lord would not hear him," implies the possibility that such may be the state even of believers; and there is abundant reason to fear that it is in this way their prayers are so often hindered, and their supplications so frequently remain unanswered. Nor is it difficult to conceive how believers may be chargeable with regarding iniquity in their heart, even amidst all the solemnity of coming into the immediate presence of God, and directly addressing him in the language of prayer and supplication. It is possible that they may put themselves into such a situation, in a state of mind but little fitted for engaging in that holy exercise; the world, in one form or another, may for the time have the ascendancy in their hearts; and there may have been so much formality in their confessions, and so much indifference in their supplications, that when the exercise is over, they could not honestly declare that they really meant what they acknowledged, or seriously desired what they prayed for. A Christian, it is true, could not be contented to remain in a state like this; and, when he is awakened from it, as he sooner or later will be, he cannot fail to look back upon it with humiliation and shame. But we fear there are seasons in which believers themselves may make a very near approach to such a state; and what then is the true interpretation of prayers offered up at such a moment? It is in fact saying, that there is something which, for the time, they prefer to what they are formally asking of God; that, though the blessing which they do ask may be for a time withheld, yet they would find a compensation in the enjoyment of the worldly things which do at the moment engross their affections; and that, in reality, they would not choose to have at that instant such an abundant communication of spiritual influence imparted to them, as would render these worldly objects less valuable in their estimation, and would turn the whole tide of their affections towards spiritual things... The Christian may sometimes betake himself to prayer, to ask counsel of God in some perplexity regarding divine truth, or to seek direction in some doubtful point of duty; but, instead of being prepared fairly to exercise his judgment in the hope that, while doing so, the considerations that lie of the side of truth will be made to his mind clear and convincing; he may have allowed his inclinations so to influence and bias his judgment towards the side of error, or in favour of the line of conduct which he wishes to pursue, that when he asks counsel it may only be in the hope that his previous opinion will be confirmed, and when he seeks direction it is in reality on a point about which he was previously determined... Another case is, I fear, but too common, and in which the believer may be still more directly chargeable with regarding iniquity in his heart. It is possible that there may be in his heart or life something which he is conscious is not altogether as it should be -- some earthly attachment which he cannot easily justify -- or some point of conformity to the maxims and practices of the world, which he finds it difficult to reconcile with christian principle; and yet all the struggle which these have from time to time cost him, may only have been an effort of ingenuity on his part to retain them without doing direct violence to conscience -- a laborious getting up of arguments whereby to show how they may be defended, or in what way they may lawfully be gone into; while the true and simple reason of his going into them, namely, the love of the world, is all the while kept out of view. And, as an experimental proof of how weak and inconclusive all these arguments are, and at the same time how unwilling he still is to relinquish his favourite objects, he may be conscious that in confessing his sins he leaves them out of the enumeration, rather because he would willingly pass them over, than because he is convinced that they need not be there; he may feel that he cannot and dare not make them the immediate subject of solemn and deliberate communing with God; and, after all his multiplied and ingenuous defences, he may be reconciled to them at last, only by ceasing to agitate the question whether they are lawful or not. Robert Gordon, D.D., 1825.

Verse 18. Whence is it that a man's regarding or loving sin in his heart hinders his prayers from acceptance with God?

  1. The first reason is, because in this case he cannot

    pray by the Spirit. All prayers that are acceptable

    with God are the breathings of his own Spirit with us.

    Ro 8:26 . As without the intercession of Christ we

    cannot have our prayers accepted, so without the

    intercession of the Spirit we cannot pray...
  1. The second reason is, because as long as a man

    regards iniquity in his heart he cannot pray in faith;

    that is, he cannot build a rational confidence upon any

    promise that God will accept him. Now, faith always

    respects the promise, and promise of acceptance is made

    only to the upright: so long, therefore, as men cherish

    a love of sin in their heart, they either understand

    not the promises, and so they pray without

    understanding, or they understand them, and yet

    misapply them to themselves, and so they pray in

    presumption: in neither case, they have little cause to

    hope for acceptance...

  1. The third reason is, because while we regard iniquity in our hearts we cannot pray with fervency; which, next to sincerity, is the great qualification of prayer, to which God has annexed a promise of acceptance ( Matthew 11:12 ): "The kingdom of heaven suffereth violence, and the violent take it by force." Matthew 7:7 : those only that seek are like to find, and those that knock to have admittance; all which expressions denote vehemence and importunity. Now, the cause of vehemence, in our prosecution of any good, is our love of it; for proportionable to the affection we bear to anything is the earnestness of our desires and the diligence of our pursuit after it. So long, therefore, as the love of sin possesses our hearts, our love to spiritual things is dull, heavy, inactive, and our prayers for them must needs be answerable. O the wretched fallacy that the soul will here put upon itself! At the same time it will love its sin and pray against it; at the same time it will entreat for grace, with a desire not to prevail: as a father confesses of himself, that before his conversion he would pray for chastity, with a secret reserve in his wishes that God would not grant his prayer. Such are the mysterious, intricate treacheries by which the love of sin will make a soul deceive and circumvent itself. How languidly and faintly will it pray for spiritual mercies; conscience, in the meanwhile, giving the lie to every such petition! The soul, in this case, cannot pray against sin in earnest; it fights against it, but neither with hope nor intent to conquer; as lovers, usually, in a game one against another, with a desire to lose. So, then, while we regard iniquity, how is it possible for us to regard spiritual things, the only lawful object of our prayers? and, if we regard them not, how can we be urgent with God for the giving of them? And where there is no fervency on our part, no wonder if there is no answer on God's. Robert South, 1633-1716.

Verse 18. If I regard iniquity in my heart, the Lord will not hear me. Though the subject matter of a saint's prayer be founded on the word, yet if the end he aims at be not levelled right, this is a door at which his prayer will be stopped: "Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts." James 4:3 . Take, I confess, a Christian in his right temper, and he aims at the glory of God; yet, as a needle that is touched with a loadstone may be removed from its point to which nature hath espoused it, though trembling till it again recovers it; so a gracious soul may in a particular act and request vary from this end, being jogged by Satan, yea, disturbed by an enemy nearer home -- his own unmortified corruption. Do you not think it possible for a saint, in distress of body and spirit, to pray for health in the one, and comfort in the other, with too selfish a respect to his own ease and quiet? Yes, surely; and to pray for gifts and assistance in some eminent service, with an eye to his own credit and applause; to pray for a child with too inordinate a desire that the honour of his house may be built up in him. And this may be understood as the sense, in part, of that expression, If I regard iniquity in my heart, the Lord will not hear me. For though to desire our own health, peace, and reputation, be not an iniquity, when contained within the limits that God hath set; yet, when they overflow at such a height, as to overtop the glory of God, yea, to stand but in a level with it, they are a great abomination. That which in the first or second degree is wholesome food, would be rank poison in the fourth or fifth: therefore, Christian, catechize thyself, before thou prayest: O, my soul, what sends thee on this errand? Know but thy own mind what thou prayest for, and thou mayest soon know God's mind how thou shalt speed. Secure God his glory, and thou mayest soon know God's mind how thou shalt speed. William Gurnall.

Verse 18. If I regard iniquity in my heart, the Lord will not hear me.

  1. They regard iniquity in their heart, who practise it secretly, who are under restraint from the world, but are not possessed of an habitual fear of the omniscient God, the searcher of all hearts, and from whose eyes there is no covering of thick darkness where the workers of iniquity may hide themselves. Jeremiah 23:24 .
  2. They regard iniquity in the heart, who entertain and indulge the desire of sin, although in the course of providence they may be restrained from the actual commission of it. I am persuaded the instances are not rare, of men feeding upon sinful desires, even when through want of opportunity, through the fear of man, or through some partial restraint of conscience, they dare not carry them into execution.
  3. They regard iniquity in their heart, who reflect upon past sins with delight, or without sincere humiliation of mind. Perhaps our real disposition, both towards sin and duty, may be as certainly discovered by the state of our minds after, as in the time of action. The strength and suddenness of temptation may betray even a good man into the commission of sin; the backwardness of heart and power of inward corruption may make duty burdensome and occasion many defects in the performance; but every real Christian remembers his past sins with unfeigned contrition of spirit, and a deep sense of unworthiness before God; and the discharge of his duty, however difficult it may have been at the time, affords him the utmost pleasure on reflection. It is otherwise with many; they can remember their sins without sorrow, they can speak of them without shame, and sometimes even with a mixture of boasting and vain glory. Did you never hear them recall their past follies, and speak of them with such relish, that it seems to be more to renew the pleasure than to regret the sin? Even supposing such persons to have forsaken the practice of some sin, if they can thus look upon them with inward complacency, their seeming reformation must be owing to a very different cause from renovation of heart.
  4. They regard iniquity in their heart, who look upon the sins of others with approbation; or, indeed, who can behold them without grief. Sin is so abominable a thing, so dishonouring to God, and so destructive to the souls of men, that no real Christian can witness it without concern. Hence it is so frequently taken notice of in Scripture, as the character of a servant of God, that he mourns for the sins of others. Psalms 119:136 Psalms 119:158 .
  5. In the last place, I suspect that they regard sin in the heart, who are backward to bring themselves to the trial, and who are not truly willing that God himself would search and try them. If any, therefore, are unwilling to be tried, if they are backward to self examination, it is an evidence of a strong and powerful attachment to sin. It can proceed from nothing but from a secret dread of some disagreeable discovery, or the detection of some lust which they cannot consent to forsake... There are but too many who though they live in the practice of sin, and regard iniquity in their hearts, do yet continue their outward attendance on the ordinances of divine institution, and at stated times lay hold of the seals of God's covenant. Shall they find any acceptance with him? No. He counts it a profane mockery; he counts it a sacrilegious usurpation. Psalms 50:16-17 . Shall they have any comfort in it? No: unless in so far as in righteous judgment he suffers them to be deceived; and they are deceived, and they are most unhappy, who lie longest under the delusion. Ps 50:21. Shall they have any benefit by it? No: instead of appeasing his wrath, it provokes his vengeance; instead of enlightening their minds, it blinds their eyes; instead of sanctifying their nature, it hardens their hearts. See a description of those who had been long favoured with outward privileges and gloried in them. John 12:39-40 . So that nothing is more essential to an acceptable approach to God in the duties of his worship in general, and particularly to receiving the seals of his covenant, than a thorough and universal separation from all known sin. Job 11:13-14 . John Witherspoon (1722-1749), in a Sermon entitled "The Petitions of the Insincere Unavailing."

Verse 18-20. Lord, I find David making a syllogism, in mood and figure, two propositions he perfected. If I regard iniquity in my heart, the Lord will not hear me; but verily God hath heard me; he hath attended to the voice of my prayer. Now I expected that David should have concluded thus: "Therefore I regard not wickedness in my heart; but far otherwise he concludes": Blessed be God, which hath not turned away my prayer, nor his mercy from me. Thus David had deceived, but not wronged me. I looked that he should have clapped the crown on his own, and he puts it on God's head. I will learn this excellent logic; for I like David's better than Aristotle's syllogisms, that whatsoever the premise be, I make God's glory the conclusion. Thomas Fuller.
