Psalms 139

"\nO Lord, thou hast searched me, and known [me]. The omniscience of God reaches to all persons and things; but the psalmist only takes notice of it as respecting himself. God knows all men in general, and whatever belongs to them; he knows his own people in a special manner; and he knows their particular persons, as David and others: and this knowledge of God is considered after the manner of men, as if it was the fruit of search, to denote the exquisiteness of it; as a judge searches out a cause, a physician the nature of a disease, a philosopher the reason of things; who many times, after all their inquiries, fail in their knowledge; but the Lord never does: his elect lie in the ruins of the fall, and among the men of the world; he searches them out and finds them; for be knows where they are, and the time of finding them, and can distinguish them in a crowd of men from others, and notwithstanding the sad case they are in, and separates them from them; and he searches into them, into their most inward part, and knows them infinitely better than their nearest relations, friends and acquaintance do; he knows that of them and in them, which none but they themselves know; their thoughts, and the sin that dwells in them: yea, he knows more of them and in them than they themselves, Jer 17:9. And he knows them after another manner than he does other men: there are some whom in a sense he knows not; but these he knows, as he did David, so as to approve of, love and delight in, Mt 7:23.\n\n\n "

139:1-6 God has perfect knowledge of us, and all our thoughts and actions are open before him. It is more profitable to meditate on Divine truths, applying them to our own cases, and with hearts lifted to God in prayer, than with a curious or disputing frame of mind. That God knows all things, is omniscient; that he is every where, is omnipresent; are truths acknowledged by all, yet they are seldom rightly believed in by mankind. God takes strict notice of every step we take, every right step and every by step. He knows what rule we walk by, what end we walk toward, what company we walk with. When I am withdrawn from all company, thou knowest what I have in my heart. There is not a vain word, not a good word, but thou knowest from what thought it came, and with what design it was uttered. Wherever we are, we are under the eye and hand of God. We cannot by searching find how God searches us out; nor do we know how we are known. Such thoughts should restrain us from sin.

PSALM 139 Some of the Jewish doctors are of opinion that this is the most excellent of all the psalms of David; and a very pious devout meditation it is upon the doctrine of God’s omniscience, which we should therefore have our hearts fixed upon and filled with in singing this psalm. I. This doctrine is here asserted, and fully laid down (v. 1-6). II. It is confirmed by two arguments:—1. God is every where present; therefore he knows all (v. 7–12). 2. He made us, therefore he knows us (v. 13–16). III. Some inferences are drawn from this doctrine. 1. It may fill us with pleasing admiration of God (v. 17, 18). 2. With a holy dread and detestation of sin and sinners (v. 19–22). 3. With a holy satisfaction in our own integrity, concerning which we may appeal to God (v. 23, 24). This great and self-evident truth, That God knows our hearts, and the hearts of all the children of men, if we did but mix faith with it and seriously consider it and apply it, would have a great influence upon our holiness and upon our comfort.To the chief musician. A psalm of David.Verses 1-6 David here lays down this great doctrine, That the God with whom we have to do has a perfect knowledge of us, and that all the motions and actions both of our inward and of our outward man are naked and open before him.I. He lays down this doctrine in the way of an address to God; he says it to him, acknowledging it to him, and giving him the glory of it. Divine truths look fully as well when they are prayed over as when they are preached over, and much better than when they are disputed over. When we speak of God to him himself we shall find ourselves concerned to speak with the utmost degree both of sincerity and reverence, which will be likely to make the impressions the deeper.II. He lays it down in a way of application to himself, not, "Thou hast known all," but, "Thou hast known me; that is it which I am most concerned to believe and which it will be most profitable for me to consider." Then we know these things for our good when we know them for ourselves, Job 5:27. When we acknowledge, "Lord, all souls are thine," we must add, "My soul is thine; thou that hatest all sin hatest my sin; thou that art good to all, good to Israel, art good to me." So here, "Thou hast searched me, and known me; known me as thoroughly as we know that which we have most diligently and exactly searched into." David was a king, and the hearts of kings are unsearchable to their subjects (Prov. 25:3), but they are not so to their Sovereign.III. He descends to particulars: "Thou knowest me wherever I am and whatever I am doing, me and all that belongs to me." 1. "Thou knowest me and all my motions, my down-sitting to rest, my up-rising to work, with what temper of mind I compose myself when I sit down and stir up myself when I rise up, what my soul reposes itself in as its stay and support, what it aims at and reaches towards as its felicity and end. Thou knowest me when I come home, how I walk before my house, and when I go abroad, on what errands I go." 2. "Thou knowest all my imaginations. Nothing is more close and quick than thought; it is always unknown to others; it is often unobserved by ourselves, and yet thou understandest my thought afar off. Though my thoughts be ever so foreign and distant from one another, thou understandest the chain of them, and canst make out their connexion, when so many of them slip my notice that I myself cannot.
