I. What kind of understanding or knowledge there is in God. The knowledge of God in Scripture hath various names, according to the various relations or objects of it: in respect of present things, it is called knowledge or sight; in respect of things past, remembrance; in respect of things future, or to come, it is called foreknowledge, or prescience (1 Pet. i. 2); in regard of the universality of the objects, it is called omniscience; in regard to the simple understanding of things, it is called knowledge; in regard of acting and modelling the ways of acting, it is called wisdom and prudence (Eph. i. 8). He must have knowledge, otherwise he could not be wise; wisdom is the flower of knowledge, and knowledge is the root of wisdom. As to what this knowledge is, if we know what knowledge is in man, we may apprehend what it is in God, removing all imperfection from it, and ascribing to him the most eminent way of understanding; because we cannot comprehend God, but as he is pleased to condescend to us in his own ways of discovery, that is, under some way of similitude to his perfectest creatures, therefore we have a notion of God by his understanding and will; understanding, whereby he conceives and apprehends things; will, whereby he extends himself in acting according to his wisdom, and whereby he doth approve or disapprove; yet we must not measure his understanding by our own, or think it to be of so gross a temper as a created mind; that he hath eyes of flesh, or sees or knows as mansees (Job x. 4). We can no more measure his knowledge by ours than we can measure his essence by our essence. As he hath an incomprehensible essence, to which ours is but as a drop of a bucket, so he hath an incomprehensible knowledge, to which ours is but as a grain of dust, or mere darkness: his thoughts are above our thoughts, as the heavens are above the earth. The knowledge of God is variously divided by the schools, and acknowledged by all divines.
1. A knowledge visionis et simplicis intelligentiæ; the one we may call a sight, the other an understanding; the one refers to sense, the other to the mind. (1.) A knowledge of vision or sight. Thus God knows himself and all things that really were, are, or shall be in time; all those things which he hath decreed to be, though they are not yet actually sprung up in the world, but lie couchant in their causes. (2.) A knowledge of intelligence or simple understanding.The object of this is not things that are in being, or that shall by any decree of God ever be existent in the world, but such things as are possible to be wrought by the power of God, though they shall never in the least peep up into being, but lie forever wrapt up in darkness and nothing.[681] This also is a necessary knowledge to be allowed to God, because the object of this knowledge is necessary. The possibility of more creatures than ever were or shall be, is a conclusion that hath a necessary truth in it; as it is necessary that the power of God can produce more creatures, though it be not necessary that it should produce more creatures, so it is necessary that whatsoever the power of God can work, is possible to be. And as God knows this possibility, so he knows all the objects that are thus possible; and herein doth much consist the infiniteness of his knowledge, as shall be shown presently. These two kinds of knowledge differ; that of vision, is of things which God hath decreed to be, though they are not yet; that of intelligence is of things which never shall be; yet they may be, or are possible to be, if God please to will and order their being; one respects things that shall be, the other, things that may be, and are not repugnant to the nature of God to be. The knowledge of vision follows the act of God’s will, and supposeth an act of God’s will before, decreeing things to be. (If we could suppose any first or second in God’s decree, we might say God knew them as possible before he decreed them; he knew them as future, because he decreed them.) For without the will of God decreeing a thing to come to pass, God cannot know that it will infallibly come to pass. But the knowledge of intelligence stands without any act of his will, in order to the being of those things he knows; he knows possible things only in his power; he knows other things both in his power as able to effect them, and in his will, as determining the being of them; such knowledge we must grant to be in God, for there is such a kind of knowledge in man; for man doth not only know and see what is before his eyes in this world, but he may have a conception of many more worlds, and many more creatures, which he knows are possible to the power of God.
2. There is a speculative and practical knowledge in God. (1.) Aspeculative knowledge is, when the truth of a thing is known without a respect to any working or practical operation.The knowledge of things possible is in God only speculative,[682] and some say God’s knowledge of himself is only speculative, because there is nothing for God to work in himself: and though he knows himself, yet this knowledge of himself doth not terminate there, but flowers into a love of himself, and delight in himself; yet this love of himself, and delight in himself, is not enough to make it a practical knowledge, because it is natural, and naturally and necessarily flows from the knowledge of himself and his own goodness: he cannot but love himself, and delight in himself, upon the knowledge of himself. But that which is properly practice, is where there is a dominion over the action, and it is wrought not naturally and necessarily, but in a way of freedom and counsel. As when we see a beautiful flower or other thing, there ariseth a delight in the mind; this no man will call practice, because it is a natural affection of the will, arising from the virtue of the object, without any consideration of the understanding in a practical manner by counselling, commanding, &c. (2.) A practical knowledge: which tends to operation and practice, and is the principle of working about things that are known; as the knowledge an artificer hath in an art or mystery. This knowledge is in God: the knowledge he hath of the things he hath decreed, is such a kind of knowledge; for it terminates in the act of creation, which is not a natural and necessary act, as the loving himself, and delighting in himself is, but wholly free: for it was at his liberty whether he would create them or no; this is called discretion (Jer. x. 12): “He hath stretched out the heavens by his discretion.” Such also is his knowledge of the things he hath created, and which are in being, for it terminates in the government of them for his own glorious ends. It is by this knowledge “the depths are broken up, and the clouds drop down their dew” (Prov. iii. 20). This is a knowledge whereby he knows the essence, qualities, and properties of what he creates and governs in order to his own glory, and the common good of the world over which he resides; so that speculative knowledge is God’s knowledge of himself and things possible; practical knowledge is his knowledge of his creatures and things governable; yet in some sort this practical knowledge is not only of things that are made, but of things which are possible, which God might make, though he will not: for as he knows that they can be created, so he knows how they are to be created, and how to be governed, though he never will create them.This is a practical knowledge: for it is not requisite to constitute a knowledge practical, actually to act, but that the knowledge in itself be referable to action.[683]
3. There is a knowledge of approbation, as well as apprehension. This the Scripture often mentions. Words of understanding are used to signify the acts of affection. This knowledge adds to the simple act of the understanding, the complacency and pleasure of the will, and is improperly knowledge, because it belongs to the will, and not to the understanding; only it is radically in the understanding, because affection implies knowledge: men cannot approve ofthat which they are ignorant of. Thus knowledge is taken (Amos iii. 2), “You only have I known of all the families of the earth;” and (2 Tim. ii. 19), “The Lord knows who are his,” that is, he loves them; he doth not only know them, but acknowledges them for his own. It notes, not only an exact understanding, but a special care of them; and so is that to be understood (Gen. i.), “God saw every thing that he had made, and behold it was very good:” that is, he saw it with an eye of approbation, as well as apprehension. This is grounded upon God’s knowledge of vision, his sight of his creatures; for God doth not love or delight in anything but what is actually in being, or what he hath decreed to bring into being. On the contrary, also, when God doth not approve, he is said not to know (Matt. xxv. 12), “I know you not,” and (Matt. vii. 23), “I never knew you;” he doth not approve of their works. It is not an ignorance of understanding, but an ignorance of will; for while he saith he never knew them, he testifies that he did know them, in rendering the reason of his disapproving them, because he knows all their works: so he knows them, and doth not know them in a different manner: he knows them so as to understand them, but he doth not know them so as to love them. We must, then, ascribe an universal knowledge to God. If we deny him a speculative knowledge, or knowledge of intelligence, we destroy his Deity, we make him ignorant of his own power: if we deny him practical knowledge, we deny ourselves to be his creatures; for, as his creatures, we are the fruits of this, his discretion, discovered in creation: if we deny his knowledge of vision, we deny his governing dominion. How can he exercise a sovereign and uncontrollable dominion, that is ignorant of the nature and qualities of the things he is to govern? If he had not knowledge he could make no revelation; he that knows not cannot dictate; we could then have no Scripture. To deny God knowledge, is to dash out the Scripture, and demolish the Deity. God is described in Zech. iii. 9, “with seven eyes,” to show his perfect knowledge of all things, all occurrences in the world; and the cherubims, or whatsoever is meant by the wings, are described to be full of eyes, both “before and behind” (Ezek. i. 18), round about them; much more is God all eye, all ear, all understanding. The sun is a natural image of God; if the sun had an eye, it would see; if it had an understanding, it would know all visible things; it would see what it shines upon, and understand what it influenceth, in the most obscure bowels of the earth. Doth God excel his creature, the sun, in excellency and beauty, and not in light and understanding? certainly more than the sun excels an atom or grain of dust. We may yet make some representation of this knowledge of God by a lower thing, a picture, which seems to look upon every one, though there be never so great a multitude in the room where it hangs; no man can cast his eye upon it, but it seems to behold him in particular, and so exactly, as if there were none but him upon whom the eye of it were fixed; and every man finds the same cast of it: shall art frame a thing of that nature, and shall not the God of art and all knowledge, be much more in reality than that is in imagination? Shall not God have a far greater capacity to behold everything inthe world, which is infinitely less to him than a wide room to a picture?
II. The second thing, What God knows; how far his understanding reaches.
1. God knows himself, and only knows himself. This is the first and original knowledge, wherein he excels all creatures. No man doth exactly know himself; much less doth he understand the full nature of a spirit; much less still the nature and perfections of God; for what proportion can there be between a finite faculty and an infinite object? Herein consists the infiniteness of God’s knowledge, that he knows his own essence, that he knows that which is unknowable to any else. It doth not so much consist in knowing the creatures, which he hath made, as in knowing himself, who was never made. It is not so much infinite, because he knows all things which are in the world, or that shall be; or things that he can make, because the number of them is finite;but because he hath a perfect and comprehensive knowledge of his own infinite perfections.[684] Though it be said that angels “see his face” (Matt. xviii. 10), that sight notes rather their immediate attendance, than their exact knowledge; they see some signs of his presence and majesty, more illustrious and express than ever appeared to man in this life; but the essence of God is invisible to them, hid from them in the secret place of eternity; none knows God but himself (1 Cor. ii. 11): “What man knows the things of a man save the spirit of a man? so the things of God knows no man but the Spirit of God; the Spirit of God searches the deep things of God;” searcheth, that is, exactly knows, thoroughly understands, as those who have their eyes in every chink and crevice, to see what lies hid there; the word search notes not an inquiry, but an exact knowledge, such as men have of things upon a diligent scrutiny: as when God is said to search the heart and the reins, it doth not signify a precedent ignorance, but an exact knowledge of the most intimate corners of the hearts of men. As the conceptions of men are unknown to any but themselves, so the depths of the divine essence, perfections, and decrees, are unknown to any but to God himself; he only knows what he is, and what he knows, what he can do, and what he hath decreed to do. For first, if God did not know himself, he would not be perfect. It is the perfection of a creature to know itself, much more a perfection belonging to God. If God did not comprehend himself, he would want an infinite perfection, and so would cease to be God, in being defective in that which intellectual creatures in some measure possess.As God is the most perfect being, so he must have the most perfect understanding: if he did not understand himself, he would be under the greatest ignorance, because he would be ignorant of the most excellent object. Ignorance is the imperfection of the understanding; and ignorance of one’s self is a greater imperfection than ignorance of things without. If God should know all things without himself, and not know himself, he would not have the most perfect knowledge, because he would not have the knowledge of the bestof objects. Secondly, Without the knowledge of himself, he could not be blessed. Nothing can have any complacency in itself, without knowledge of itself. Nothing can in a rational manner enjoy itself, without understanding itself. The blessedness of God consists not in the knowledge of anything without him, but in the knowledge of himself and his own excellency, as the principle of all things; if, therefore, he did not perfectly know himself and his own happiness, he could not enjoy a happiness; for to be, and not to know to be, is as if a thing were not. “He is God, blessed forever” (Rom. ix. 5.), and therefore forever had a knowledge of himself. Thirdly, Without the knowledge of himself, he could create nothing. For he would be ignorant of his own power, and his own ability; and he that doth not know how far his power extends, could not act: if he did not know himself, he could know nothing; and he that knows nothing, can do nothing; he could not know an effect to be possible to him, unless he knew his own power as a cause. Fourthly, Without the knowledge of himself, he could govern nothing. He could not, without the knowledge of his own holiness and righteousness, prescribe laws to men, nor without a knowledge of his own nature order himself a manner of worship suitable to it. All worship must be congruous to the dignity and nature of the object worshipped: he must therefore know his own authority, whereby worship was to be enacted; his own excellency, to which worship was to be suited; his own glory, to which worship was to be directed. If he did not know himself, he did not know what to punish, because he would not know what was contrary to himself: not knowing himself, he would not know what was a contempt of him, and what an adoration of him; what was worthy of God, and what was unworthy of him. In fine, he could not know other things, unless he knew himself; unless he knew his own power, he could not know how he created things; unless he knew his own wisdom, he could not know the beauty of his works; unless he knew his own glory, he could not know the end of his works; unless he knew his own holiness, he could not know what was evil; and unless he knew his own justice, he could not know how to punish the crimes of his offending creatures. And, therefore,
(1.) God knows himself, because his knowledge, with his will, is the cause of all other things that can fall under his cognizance: he knows himself first, before he can know any other thing; that is, first according to our conceptions; for, indeed, God knows himself and all other things at once; he is the first truth, and therefore is the first object of his own understanding. There is nothing more excellent than himself, and therefore nothing more known to him than himself. As he is all knowledge, so he hath in himself the most excellent object of knowledge. To understand, is properly to know one’s self. No object is so intelligible to God as God is to himself, nor so intimately and immediately joined with his understanding as himself; for his understanding is his essence, himself.
(2.) He knows himself by his own essence. He knows not himself and his own power by the effect, because he knows himselffrom eternity, before there was a world, or any effect of his power extant. It is not a knowledge by the cause, for God hath no cause; nor a knowledge of himself by any species, or anything from without: if it were anything from without himself, that must be created or uncreated; if uncreated it would be God; and so we must either own many Gods, or own it to be his essence, and so not distinct from himself: if created, then his knowledge of himself would depend upon a creature: he could not, then, know himself from eternity, but in time, because nothing can be created from eternity, but in time. God knows not himself by any faculty, for there is no composition in God; he is not made up of parts, but is a simple being; some, therefore, have called God, not intellectus, understanding, because that savors of a faculty, but intellectio, intellection: God is all act in the knowledge of himself and his knowledge of other things.
(3.) God, therefore, knows himself perfectly, comprehensively.Nothing in his own nature is concealed from him; he reflects upon everything that he is.[685] There is a positive comprehension, so God doth not comprehend himself; for what is comprehended hath bounds, and what is comprehended by itself is finite to itself; and there is a negative comprehension—God so comprehends himself; nothing in his own nature is obscure to him, unknown by him; for there is as great a perfection in the understanding of God to know, as there is in the divine nature to be known. The understanding of God, and the nature of God, are both infinite, and so equal to one another: his understanding is equal to himself; he knows himself so well, that nothing can be known by him more perfectly than himself is known to himself. He knows himself in the highest manner, because nothing is so proportioned to the understanding of God as himself. He knows his own essence, goodness, power; all his perfections, decrees, intentions, acts, the infinite capacity of his own understanding, so that nothing of himself is in the dark to himself: and, in this respect, some use this expression, that the infiniteness of God is in a manner finite to himself, because it is comprehended by himself. Thus God transcends all creatures; thus his understanding is truly infinite, because nothing but himself is an infinite object for it: what angels may understand of themselves perfectly I know not, but no creature in the world understands himself. Man understands not fully the excellency and parts of his own nature; upon God’s knowledge of himself depends the comfort of his people, and the terror of the wicked: this is also a clear argument for his knowledge of all other things without himself; he that knows himself, must needs know all other things less than himself, and which were made by himself; when the knowledge of his own immensity and infiniteness is not an object too difficult for him, the knowledge of a finite and limited creature, in all his actions, thoughts, circumstances, cannot be too hard for him: since he knows himself, who is infinite, he cannot but know whatsoever is finite. This is the foundation of all his other knowledge; the knowledge of everything present, past,and to come, is far less than the knowledge of himself. He is more incomprehensible in his own nature, than all things created, or that can be created, put together can be. If he, then, have a perfect comprehensive knowledge of his own nature, any knowledge of all other things is less than the knowledge of himself; this ought to be well considered by us, as the fountain whence all his other knowledge flows.
2. Therefore God knows all other things, whether they be possible, past, present, or future; whether they be things that he can do, but will never do, or whether they be things that he hath done, but are not now;things that are now in being, or things that are not now existing, that lie in the womb of their proper and immediate causes.[686] If his understanding be infinite, he then knows all things whatsoever that can be known, else his understanding would have bounds, and what hath limits is not infinite, but finite. If he be ignorant of any one thing that is knowable, that is a bound to him, it comes with an exception, a but, God knows all things but this; a bar is then set to his knowledge. If there were anything, any particular circumstance in the whole creation or non‑creation, and possible to be known by him, and yet were unknown to him, he could not be said to be omniscient; as he would not be Almighty if any one thing, that implied not a repugnancy to his nature, did transcend his power.
