Psalms 139:1-24

O Lord, Thou hast searched me, and known me.

God’s exhaustive knowledge of man

This lyric has always been the subject of praise. Aben Ezra said there was none like it in the five books. Lord Brougham spoke of it as “that singularly beautiful poem” Herder said that language utterly failed him in its exposition. Erskine of Llinlathen wanted this to be before him on his death-bed. The title ascribes it to David, an ascription corroborated by its originality and majesty and its correspondence with psalms undoubtedly Davidic. Probably the Aramaic colouring is a mere dialectic variation, existing during the whole period of Hebrew history, and occasionally coming to the front as circumstances suggested it.

I. The Divine omniscience (verses 1-6). The poet multiplies expressions to indicate how complete is God’s knowledge of him. Whether he be at rest or in motion, in every posture and state, God knows him. Not only his outward acts, but the thoughts from which they spring are at once discerned. Nothing can escape Jehovah’s eye, for He is behind and before, i.e. on all sides of man, and His hand is upon him to restrain and control. The strophe closes with a frank confession of the writer’s impotence and awe. He cannot comprehend it, which is not strange, for how is the finite to comprehend the infinite? But he knows it and bows in reverence before the sublime truth.

II. The Divine omnipresence (verses 7-12). God is everywhere; not only above all as transcendent, but also through all and in all as immanent in nature. This thought is expanded and enforced by its application to all measures of space. Were man to scale the azure vault overhead, it would only confront him with the Divine personality; were he to sound unimaginable depths in the other direction, the result would be the same. H a man mounted on wings, not those of the sun (Malachi 4:2), nor of the wind (Psalms 18:10), but of the dawn, and pursued the farthest flight westward, if he should fly with the same swiftness as the first rays of the morning shoot from one end of the heavens to the other, still he would not get beyond the Divine presence. Beyond the sea, and far out of the sight of man, God’s hand would lead him, and God’s right hand grasp him.

III. Omnipotence in the creation of man (verses 13-18). The singer revolves in mind the secret processes of man’s birth and development, and gratitude overflows into praise. He sees how he has been made to differ from the inferior creation in constitution and destiny. It is a fearful distinction (Genesis 28:17). Any signal manifestation of Jehovah’s presence, however favourable, inspires awe. The consideration of this single ease leads to the general statement that all God’s works are marvellous, a statement which the writer reaffirms as from an experimental conviction of its truth. In the next verse the curious growth and unfolding of the embryo is referred to. It goes on in secret, as far from human vision as if it were deep down in some subterraneous cavern, but God sees it and directs the mysterious and complicated tissue, as if it were a piece of delicate embroidery. Even in its most rudimental form, invisible to any other ken, it is still open to His eyes, and He determines all its subsequent development, recording in His book the days to come, i.e. the various events and vicissitudes of life, even before one of them existed. Struck by this view of God’s omniscience as embracing the beginning, the unfolding and the completion of all things, the singer bursts out into a recognition of its value. To him God’s thoughts, i.e. His plans and purposes as displayed in these miracles of creation, are precious beyond measure. Nor are they few or slight, but amount to a vast sum, more numerous than the sands of the sea. They are ever before David as an object of adoring wonder, not by day only, but by night; not merely in the watches of the night, but even in his sleep. His meditations are continuous. His communion is unbroken.

IV. The practical application (verses 19-24). The greater any man’s nearness to God, the more intense is his abhorrence of the impiety which disowns or despises the living God. Nor does such a feeling indicate malevolence. “When a foul crime has been perpetrated, tender-hearted Christian women who would not harm a hair of the enemy’s head, but would rather feed him, will express keen resentment, and will be disquieted in mind till they hear that the perpetrator has been convicted and duly punished.” The conclusion of the strophe is striking. The poet returns to the opening words of the psalm, and prays for a new experience of Jehovah’s searching scrutiny, that he may not be given over to self-conceit. The petition is a proof of humility. Although he had averred so strongly his aversion to the wicked, he prays that this may be no mere outward separation. The All-seeing Eye may detect in him some way that leads to sin and sorrow, though he is unconscious of it. Hence he entreats God to see and disclose it, and then taking his hand to lead him in a way which, unlike the way of the wicked (Psalms 1:6), does not perish, but ends in everlasting life. (T. W. Chambers, D. D.)

God’s omniscience and omnipresence

I. Some Scriptural views of the Divine omniscience and omnipresence. God is everywhere present--

1. By His presence.

2. By His power or agency.

3. In the immensity of space.

4. In highest heaven.

5. In hell.

6. We cannot get away from God’s presence.

7. Human inspection is very limited. But God’s eye penetrates the darkest abode, the deepest cell, the obscurest corner, the blackest night.

8. Men only see what a man says and does; God sees all that a man is. “To Him all hearts are open, all desires known.” God knows us, not relatively, but personally.

9. Specially with His people. “Where are you going?” said Collins, the infidel, to a poor but pious man. “To church, sir,” was the reply “What to do there?” “To worship God.” “And can you tell me,” said the infidel, “whether your God is a great or a little God?” “He is both, sir.” “How can He be both?” “He is so great that the heaven of heavens cannot contain Him, and so little that He can dwell in my heart.”

II. Lessons.

1. If God is omniscient and omnipresent, then the moral character of His creatures is unveiled to His gaze, and clearly and distinctly known to Him.

2. If God is omniscient and omnipresent, then the final judgment will be a time of full and complete revelation, as well as a time of righteous retribution (Sir 11:14; Revelation 20:12). Will the disclosures of that day fill us with joy, or cover us with shame?

3. The importance of an interest in Christ.

4. Try to cherish an abiding sense of God’s presence.

5. Pray at all times and in all places.

6. Be comforted in every time of trouble. (H. Woodcock.)

The all-seeing God

I. Is there an all-seeing God? If not, whence our own existence? Whence our expectations of reward for doing right, of punishment for wrong-doing? Whence the material universe? Whence the original plan, stupendous beyond conception, more minute than the most powerful microscope can reveal, which must have preceded the first act of creation? Whence the march and trend of history, always revealing “a power not ourselves, which makes for righteousness,” and which sweeps away opposition like dust before the oncoming storm? Who conceived the character of Christ, in an age overlaid and penetrated through and through with error? Whose works of grace, in that same earth, have steadily built up a kingdom of love, of peace, of righteousness? If there is a creator of the universe, He must also be its sustainer: He cannot press material forces into service and go and leave them, as we do a windmill to draw water, for all force depends upon Him for its existence. He who superintends all must be all-seeing, and He who presides over all history must take cognizance of every event.

II. What concern has our life, here and hereafter, with the omniscience of God?

1. That exquisite pleasure in sin, which comes from its fancied concealment, is utter folly.

2. God is patient with wrong and sin, because He sees the end from the beginning.

3. Patience under trial and strength in adversity thrive under the all-seeing eye.

4. The friends of God are glad in the sure hope of being more and more consciously under His eye.

5. Corresponding judgments await those who, shrinking from that all-seeing eye, with a repugnance predominant and increasing, must abide its searchings for ever.

6. How priceless the blood of Calvary, in which the saints have “washed their robes and made them white”! (Monday Club Sermons.)

The all-seeing and all-present One

I. The all-seeing One.

1. He sees the whole of an object. At best we can only see the outside of a thing, the curve, the angle, the colour.

2. He sees the whole of every object. How few are the objects we see even thus externally and partially! Some are too small and some too distant. But He sees all, His eye takes in the immeasurable universe.

3. He sees the whole of everything at the same time.

II. The all-present One.

1. He is present everywhere, in the entirety of Himself.

2. He is present in all things, yet distinct from all things.

Practically, this subject serves three important purposes.

1. To refute some popular errors of human life.

(1) There is the error that supposes that formal worship can be of any real worth. “God is a Spirit,” etc.

(2) There is the error that imagines that death will make some fundamental alteration in their relation to God.

2. To reprove some prevalent impieties in human conduct.

(1) Atheism.

(2) Indifferentism.

3. To reveal the supreme interest of human life. Cultivate a loving affection for Him. (Homilist.)

God and ourselves

This psalm sings of--

I. God.

1. His omniscience.

(1) He knows our actions, ways, words, thoughts.

(2) His knowledge of us is entire, complete.

2. His omnipresence. He is in--

(1) Heaven.

(2) Unseen world.

(3) Everywhere.

(4) In the dark as well as the light.

3. His omnipotence (Psalms 139:13).

4. The separate, personal thinking of God toward every one of us.

(1) Innumerable.

(2) Constant.

II. Ourselves. Our relation toward such a God should be--

1. That of adoring and constantly thoughtful reverence (verses 17, 18).

2. That of siding with Him against evil (Psalms 139:19).

3. That of welcoming the Divine searching (verses 23, 24). Said Milton, speaking of his travels abroad when a young man: “I again take God to witness that in all places where so many things are considered lawful, I lived sound and untouched from all profligacy and vice, having this thought perpetually with me, that though I might escape the eyes of men, I certainly could not the eyes of God.”

4. That of a prayerful seeking of the Divine guidance (verse 24). (W. Hoyt, D. D.)

God’s knowledge of man

One of the most remarkable characteristics of a rational being is the power of self-inspection. Like the air we breathe, like the light we see, it involves a mystery that no man has ever solved. Self-consciousness has been the problem of the philosophic mind in all ages; and the mystery is not yet unravelled. But if that knowledge whereby man knows himself is mysterious, then certainly that whereby God knows him is far more so. That act whereby another being knows my secret thoughts and inmost feelings is most certainly inexplicable.

I. God accurately and exhaustively knows all that man knows of himself. He may be an uncommonly thoughtful person, and little of what is done within his soul may escape his notice; nay, we will make the extreme supposition that he arrests every thought as it rises, and looks at it; that he analyzes every sentiment as it swells his heart; that he scrutinizes every purpose as it determines his will; even if he should have such a thorough and profound self-knowledge as this, God knows him equally profoundly and equally thoroughly. Nay, more, this process of self-inspection may go on indefinitely, and the man grow more and more thoughtful, and obtain an everlastingly augmenting knowledge of what he is and what he does, so that it shall seem to him that he is penetrating so deeply into those dim and shadowy regions of consciousness where the external life takes its very first start, and then he may be sure that God understands the thought that is afar off, and deep down, and that at this lowest range and plane in his experience he besets him behind and before.

II. God accurately and exhaustively knows all that man might, but does not, know of himself. Though the transgressor is ignorant of much of his sin, because, at the time of its commission, he sins blindly as well as wilfully, and unreflectingly as well as freely; and though the transgressor has forgotten much of that small amount of sin, of which he was conscious, and by which he was pained, at the time of its perpetration; though, on the side of man, the powers of self-inspection and memory have accomplished so little towards this preservation of man’s sin, yet God knows it all, and remembers it all. He compasseth man’s path, and his lying down, and is acquainted with all his ways. And here let us look upon the bright as well as the dark side of this subject. For if God’s exhaustive knowledge of the human heart waken dread in one of its aspects, it starts infinite hope in another. If that Being has gone down into these depths of human depravity, and seen it with a more abhorring glance than could ever shoot from a finite eye, and yet has returned with a cordial offer to forgive it all, and a hearty proffer to cleanse it all away, then we can lift up the eye in adoration and in hope. The worst has been seen, and that too by the holiest of beings, and yet eternal glory is offered to us! It is perfectly plain from the elevated central point of view where we now stand, and in the focal light in which we now see, that no man can be justified before God upon the ground of personal character; for that character, when subjected to God’s exhaustive scrutiny, withers and shrinks away. Before the Searcher of hearts all mankind must appeal to mere and sovereign mercy. Justice, in this reference, is out of the question. Now, in this condition of things, God so loved the world that He gave His only-begotten Son, that whosoever believeth in Him might not perish, but have everlasting life. The simple question, then, which meets us is, Wilt thou know thyself here, and now, that thou mayest accept and feel God’s pity; or wilt thou keep within the screen, and not know thyself until beyond the grave, and then feel God’s judicial wrath? The self-knowledge, remember, must come in the one way or the other. It is a simple question of time; a simple question whether it shall come here in this world, where the blood of Christ “freely” flows, or in the future world, where “there remaineth no more sacrifice for sin.” (W. G. T. Shedd, D. D.)

God’s presence

The fact that God is always present and knows every minute trifle in our lives, and that His unerring judgment will assuredly take count of every detail of our character and our conduct, neither exaggerating nor omitting, but applying absolute justice; this truth is one of those which lose force from their very universality. God has made us so. We become unconscious of everything by long use. We could never discharge our duties properly if we were to be perpetually distracted by the consciousness of what was around us: and, above all, we might be daunted by the perpetual thought of the presence of God, and so be paralyzed instead of helped. There is, therefore, nothing wrong in our forgetting that we are in the presence of God any more than there is anything foolish in our forgetting that we need air to breathe or light to see by, or that if we fall we may hurt ourselves: just in the same way as we very often, and quite rightly, forget that we are in the company of men who will take notice of our faults. The right state of mind plainly is to have the thought of God’s presence so perpetually at hand that it shall always start before us whenever it is wanted. So that whenever we are on the point of doing or saying anything cowardly, or mean, or false, or impure, or proud, or conceited, or unkind, the remembrance that God is looking on shall instantly flash across us and help us to beat down our enemy. This is living with God. This is the communion with Him, and with Christ, which unquestionably helps the struggling, the penitent, the praying, more than anything else. And this perpetual though not always conscious sense of God’s presence would, no doubt, if we would let it have its perfect work, gradually act on our characters just as the presence of our fellow-men does. We cannot live long with men without catching something of their manner, of their mode of thought, of their character, of their government of themselves. Those who live much in a court acquire courtly manners. Those who live much in refined and educated society acquire refinement insensibly. Those who are always hearing pure and high principles set forth as the guides of life learn to value and to know them even faster than they can learn to live by them. From the just we learn justice; from the charitable we catch an infection of charity; from the generous we receive the instinct of generosity. So, too, by living in the presence of God and, as it were, in the courts of heaven, we shall assuredly learn something of a heavenly tone, and shake off some of that coarse worldliness, that deeply ingrained selfishness, that silly pride and conceit which now spoils our very best service. In short, to live with God is to be perpetually rising above the world; to live without Him is to be perpetually sinking into it, and with it, and below it. And lest the presence of God should be too much for us, Christ has taken human nature on Him, and has provided that He will be always with us as long as the world shall last. How shall we learn to walk by His side? The daily prayer in the closet, the endeavour to keep the attention fixed when praying with others, either in our regular services or in family worship the regular habit of reading the Bible at a fixed time, the occasional reminders of ourselves that God is looking on,--these are our chief means of learning to remember His presence. But yet there is another, not less powerful than any, which deserves special mention. Our hearts will put us in mind of God’s eye being upon us every now and then involuntarily. The thought will flash across us that God sees us. And this will generally be just when we are tempted to do wrong, or perhaps just when we are actually beginning to do it: some secret sin of which no one knows or dreams perhaps, some self-indulgence, which we dare not deny that God condemns. Then is the moment to choose whether or not we will live in the presence of God; then when the finger of conscience is pointing to Him and saying, “He is looking at you.” (Archbishop Temple.)

God all-seeing

In the mythology of the heathen, Momus, the god of fault-finding, is represented as blaming Vulcan, because in the human form, which he had made of clay, he had not placed a window in the breast, by which whatever was done or thought there might easily be brought to light. We do not agree with Momus, neither are we of his mind who desired to have a window in his breast that all men might see his heart. If we had such a window we should pray for shutters, and should keep them closed.

God omniscient

While the Americans were blockading Cuba, several captains endeavoured to elude their vigilance by night, trusting that the darkness would conceal them as they passed between the American war-ships. But in almost every case the dazzling rays of a searchlight frustrated the attempt, and the fugitives’ vessel was captured by the Americans. The brilliant searchlight sweeping the broad ocean and revealing even the smallest craft on its surface is but a faint type of the Eternal Light from which no sinner can hide his sin. (Weekly Pulpit.)
