5. If God were not a Spirit, he could not be an independent being. Whatsoever is compounded of many parts depends either essentially or integrally upon those parts; as the essence of a man depends upon the conjunction and union of his two main parts, his soul and body; when they are separated, the essence of a man ceaseth: and the perfection of a man depends upon every member of the body; so that if one be wanting the perfection of the whole is wanting: as if a man hath lost a limb, you call him not a perfect man, because that part is gone upon which his perfection as an entire man did depend. If God therefore had a body, the perfection of the Deity would depend upon every part of that body; and the more parts he were compounded of, the more his dependency would be multiplied according to the number of those parts of the body: for that which is compounded of many parts is more dependent than that which is compounded of fewer. And because God would be a dependent being if he had a body, he could not be the first being; for the compounding parts are in order of nature before that which is compounded by them; as the soul and body are before the man which results from the union of them. If God had parts and bodily members as we have, or any composition, the essence of God would result from those parts, and those parts be supposed to be before God. For that which is a part, is before that whose part it is. As in artificial things you may conceive it: all the parts of a watch or clock are in time before that watch which is made by setting those parts together. In natural things you must suppose the members of a body framed before you can call it a man; so that the parts of this body are before that which is constituted by them. We can conceive no other of God, if he were not a pure, entire, unmixed Spirit. If he had distinct parts, he would depend upon them; those parts would be before him; his essence would be the effect of those distinct parts, and so he would not be absolutely and entirely the first being; but he is so (Isa. xliv. 6): “I am the first, and I am the last.” He is the first; nothing is before him. Whereas, if he had bodily parts, and those finite, it would follow, God is made up of those parts which are not God; and that which is not God, is in order of nature before that which is God. So that we see if God were not a Spirit he could not be independent.
6. If God were not a Spirit, he were not immutable and unchangeable. His immutability depends upon his simplicity. He is unchangeable in his essence, because he is a pure and unmixed spiritual Being. Whatsoever is compounded of parts may be divided into those parts, and resolved into those distinct parts which make up and constitute the nature. Whatsoever is compounded is changeable in its own nature, though it should never be changed. Adam, who was constituted of body and soul, had he stood in innocence, had not died; there had been no separation made between his soul and body whereof he was constituted, and his body had not resolved into those principles of dust from whence it was extracted. Yet in his own nature he was dissoluble into those distinct parts whereof he was compounded; and so the glorified saints in heaven, after the resurrection, and the happy meeting of their souls and bodies in a new marriage knot, shall never be dissolved; yet in their own nature they are mutable and dissoluble, and cannot be otherwise, because they are made up of such distinct parts that may be separated in their own nature, unless sustained by the grace of God: they are immutable by will, the will of God, not by nature. God is immutable by nature as well as will: as he hath a necessary existence, so he hath a necessary unchangeableness (Mal. iii. 6), “I, the Lord, change not.” He is as unchangeable in his essence as in his veracity and faithfulness: they are perfections belonging to his nature. But if he were not a pure Spirit, he could not be immutable by nature.
7. If God were not a pure Spirit, he could not be omnipresent. He is in heaven above, and the earth below;359 he fills heaven and earth.360 The divine essence is at once in heaven and earth; but it is impossible a body can be in two places at one and the same time. Since God is everywhere, he must be spiritual. Had he a body, he could not penetrate all things; he would be circumscribed in place. He could not be everywhere but in parts, not in the whole; one member in one place, and another in another; for to be confined to a particular place, is the property of a body: but, since he is diffused through the whole world, higher than heaven, deeper than hell, longer than the earth, broader than the sea,361 he hath not any corporeal matter. If he had a body wherewith to fill heaven and earth, there could be no body besides his own: it is the nature of bodies to bound one another, and hinder the extending of one another. Two bodies cannot be in the same place in the same point of earth: one excludes the other; and it will follow hence that we are nothing, no substances, mere illusions; there could be no place for anybody else.362 If his body were as big as the world, as it must be if with that he filled heaven and earth, there would not be room for him to move a hand or a foot, or extend a finger; for there would be no place remaining for the motion.
8. If God were not a Spirit, he could not be the most perfect being. The more perfect anything is in the rank of creatures, the more spiritual and simple it is, as gold is the more pure and perfect that hath least mixture of other metals. If God were not a Spirit, there would be creatures of a more excellent nature than God, as angels and souls, which the Scripture call spirits, in opposition to bodies. There is more of perfection in the first notion of a spirit than in the notion of a body. God cannot be less perfect than his creatures, and contribute an excellency of being to them which he wants himself. If angels and souls possess such an excellency, and God want that excellency, he would be less than his creatures, and the excellency of the effect would exceed the excellency of the cause. But every creature, even the highest creature, is infinitely short of the perfection of God; for whatsoever excellency they have is finite and limited; it is but a spark from the sun—a drop from the ocean; but God is unboundedly perfect, in the highest manner, without any limitation; and therefore above spirits, angels, the highest creatures that were made by him: an infinite sublimity, a pure act, to which nothing can be added, from which nothing can be taken. “In him there is light and no darkness,”363 spirituality without any matter, perfection without any shadow or taint of imperfection. Light pierceth into all things, preserves its own purity, and admits of no mixture of anything else with it.
Question. It may be said, If God be a Spirit, and it is impossible he can be otherwise than a Spirit, how comes God so often to have such members as we have in our bodies ascribed to him, not only a soul, but particular bodily parts, as heart, arms, hands, eyes, ears, face, and back parts? And how is it that he is never called a Spirit in plain words, but in this text by our Saviour?
Answer. It is true, many parts of the body, and natural affections of the human nature, are reported of God in Scripture. Head,364 eyes, and eye‑lids,365 apple of the eye, mouth, &c.; our affections also, grief, joy, anger, &c. But it is to be considered,
1. That this is in condescension to our weakness. God being desirous to make himself known to man, whom he created for his glory, humbles, as it were, his own nature to such representations as may suit and assist the capacity of the creature; since by the condition of our nature nothing erects a notion of itself in our understanding, but as it is conducted in by our sense.366 God hath served himself of those things which are most exposed to our sense, most obvious to our understandings, to give us some acquaintance with his own nature, and those things which otherwise we were not capable of having any notion of. As our souls are linked with our bodies, so our knowledge is linked
