3. God is unchangeable in regard of his will and purpose. A change in his purpose is, when a man determines to do that now which before he determined not to do, or to do the contrary; when a man hates that thing which he loved, or begins to love that which he before hated; when the will is changed, a man begins to will that which he willed not before, and ceaseth to will that which he willed before. But whatsoever God hath decreed, is immutable; whatsoever God hath promised, shall be accomplished: “The word that goes forth of his mouth shall not return to him void, but it shall accomplish that which he pleaseth” (Isa. lv. 11); whatsoever “he purposeth, he will do” (Isa. xlvi. 11; Numb. xxiii. 19); his decrees are therefore called “mountains of brass” (Zech. vi. 1): brass, as having substance and solidity; mountains, as being immovable, not only by any creature, but by himself; because they stand upon the basis of infallible wisdom, and are supported by uncontrollable power. From this immutability of his will, published to man, there could be no release from the severity of the law, without satisfaction made by the death of a Mediator, since it was the unalterable will of God, that death should be the wages of sin; and from this immutable will it was, that the length of time, from the first promise of the Redeemer to his mission, and the daily provocations of men, altered not his purpose for the accomplishment of it in the fulness of that time he had resolved upon; nor did the wickedness of former ages hinder the addition of several promises as buttresses to the first. To make this out, consider,

(1.) The will of God is the same with his essence. If God had a will distinct from his essence, he would not be the most simple Being. God hath not a faculty of will distinct from himself; as his understanding is nothing else but Deus intelligens, God understanding; so his will is nothing else but Deus volens, God willing; being, therefore, the essence of God; though it is considered, according to our weakness, as a faculty, it is as his understanding and wisdom, eternal and immutable; and can no more be changed than his essence. Theimmutability of the Divine counsel depends upon that of his essence; he is the Lord Jehovah, therefore he is true to his word (Mal. iii. 6; Isa. xliii. 13): “Yea, before the day I am he, and there is none that can deliver out of my hand.” He is the same, immutable in his essence, therefore irresistible in his power.

(2.) There is a concurrence of God’s will and understanding in everything. As his knowledge is eternal, so is his purpose. Things created had not been known to be, had not God resolved them to be the act of his will; the existence of anything supposeth an act of his will. Again, as God knows all things by one simple vision of his understanding, so he wills all things by one act of volition; therefore the purpose of God in the Scripture is not expressed by counsels in the plural number, but counsel; showing that all the purposes of God are not various, but as one will, branching itself out into many acts towards the creature; but all knit in one root, all links of one chain. Whatsoever is eternal is immutable; as his knowledge is eternal, and therefore immutable, so is his will; he wills or nills nothing to be in time, but what he willed and nilled from eternity; if he willed in time that to be that he willed not from eternity, then he would know that in time which he knew not from eternity; for God knows nothing future, but as his will orders it to be future, and in time to be brought into being.

(3.) There can be no reason for any change in the will of God. When men change in their minds, it must be for want of foresight; because they could not foresee all the rubs and bars which might suddenly offer themselves; which if they had foreseen, they would not have taken such measures: hence men often will that which they afterwards wish they had not willed when they come to understand it clearer, and see that to be injurious to them which they thought to be good for them; or else the change proceeds from a natural instability without any just cause, and an easiness to be drawn into that which is unrighteous; or else it proceeds from a want of power, when men take new counsels, because they are invincibly hindered from executing the old. But none of those can be in God.

1st. It cannot be for want of foresight. What can be wanting to an infinite understanding? How can any unknown event defeat his purpose, since nothing happens in the world but what he wills to effect, or wills to permit; and therefore all future events are present with him? Besides, it doth not consist with God’s wisdom to resolve anything, but upon the highest reason; and what is the highest and infinite reason, cannot but be unalterable in itself; for there can be no reason and wisdom higher than the highest. All God’s purposes are not bare acts of will, but acts of counsel. “He works all things according to the counsel of his own will” (Eph. i. 11): and he doth not say so much that his will, as that “his counsel shall stand” (Isa. xlvi. 10). It stands, because it is counsel; and the immutability of a promise is called the “immutability of his counsel” (Heb. vi. 17), as being introduced and settled by the most perfect wisdom, and therefore to be carried on to a full and complete execution; his purpose, then, cannot be changed for want of foresight; for this would be a charge of weakness.

2d. Nor can it proceed from a natural instability of his will, or an easiness to be drawn to that which is unrighteous. If his will should not adhere to his counsel, it is because it is not fit to be followed, or because it will not follow it; if not fit to be followed, it is a reflection upon his wisdom; if it be established, and he will not follow it, there is a contrariety in God, as there is in a fallen creature, will against wisdom. That cannot be in God which he hates in a creature, viz. the disorder of faculties, and being out of their due place. The righteousness of God is like a “great mountain” (Ps. xxxvi. 6). The rectitude of his nature is as immovable in itself, as all the mountains in the world are by the strength of man. “He is not as a man, that he should repent or lie” (Numb. xxiii. 19); who often changes, out of a perversity of will, as well as want of wisdom to foresee, or want of ability to perform. His eternal purpose must either be righteous or unrighteous; if righteous and holy, he would become unholy by the change; if not righteous nor holy, then he was unrighteous before the change;which way soever it falls, it would reflect upon the righteousness of God, which is a blasphemous imagination.[602] If God did change his purpose, it must be either for the better,—then the counsel of God was bad before; or for the worse,—then he was not wise and good before.

3d. Nor can it be for want of strength. Who hath power to control him? Not all the combined devices and endeavors of men can make the counsel of God to totter (Prov. xix. 21): “There are many devices in a man’s heart; nevertheless the counsel of the Lord, that shall stand;” that, and that only shall stand. Man hath a power to devise and imagine, but no power to effect and execute of himself. God wants no more power to effect what he will, than he wants understanding to know what is fit. Well, then, since God wanted not wisdom to frame his decrees, nor holiness to regulate them, nor power to effect them, what should make him change them? since there can be no reason superior to his, no event unforeseen by him, no holiness comparable to his, no unrighteousness found in him, no power equal to his, to put a rub in his way.

4th. Though the will of God be immutable, yet it is not to be understood so, as that the things themselves so willed are immutable. Nor will the immutability of the things willed by him, follow upon the unchangeableness of his will in willing them; though God be firm in willing them, yet he doth not will that they should alway be. God did not perpetually will the doing those things which he once decreed to be done; he decreed that Christ should suffer, but he did not decree that Christ should alway suffer; so he willed the Mosaical rites for a time, but he did not will that they should alway continue; he willed that they should endure only for a time; and when the time came for their ceasing, God had been mutable if he had not put an end to them, because his will had fixed such a period. So that the changing of those things which he had once appointed to be practised, is so far from charging God with changeableness, that God would be mutable if he did not take them away; since he decreed as well their abolition at such a time, as their continuance till such atime; so that the removal of them was pursuant to his unchangeable will and decree.If God had decreed that such laws should alway continue, and afterwards changed that decree, and resolved the abrogation of them, then indeed God had been mutable; he had rescinded one decree by another; he had then seen an error in his first resolve, and there must be some weakness in the reason and wisdom whereon it was grounded.[603] But it was not so here; for the change of those laws is so far from slurring God with any mutability, that the very change of them is no other than the issue of his eternal decree; for from eternity he purposed in himself to change this or that dispensation, though he did decree to bring such a dispensation into the world. The decree itself was eternal and immutable, but the thing decreed was temporary and mutable. As a decree from eternity doth not make the thing decreed to be eternal, so neither doth the immutability of the decree render the thing so decreed to be immutable: as for example, God decreed from all eternity to create the world; the eternity of this decree did not make the world to be in being and actually created from eternity; so God decreed immutably that the world so created should continue for such a time; the decree is immutable if the world perish at that time, and would not be immutable if the world did endure beyond that time that God hath fixed for the duration of it: as when a prince orders a man’s remaining in prison for so many days; if he be prevailed with to give him a delivery before those days, or to continue him in custody for the same crime after those days, his order is changed; but if he orders the delivery of him just at that time, till which he had before decreed that he should continue in prison, the purpose and order of the prince remains firm, and the change in the state of the prisoner is the fruit of that firm and fixed resolution: so that we must distinguish between the person decreeing, the decree itself, and the thing decreed. The person decreeing, viz., God, is in himself immutable, and the decree is immutable; but the thing decreed may be mutable; and if it were not changed according to the first purpose, it would argue the decree itself to be changed; for while a man wills that this may be done now, and another thing done afterwards, the same will remains; and though there be a change in the effects, there is no change in the will.

5th. The immutability of God’s will doth not infringe the liberty of it. The liberty of God’s will consists with the necessity of continuing his purpose. God is necessarily good, immutably good; yet he is freely so, and would not be otherwise than what he is. God was free in his first purpose; and purposing this or that by an infallible and unerring wisdom, it would be a weakness to change the purpose. But, indeed, the liberty of God’s will doth not seem so much to consist in an indifferency to this or that, as in an independency on anything without himself: his will was free, because it did not depend upon the objects about which his will was conversant. To be immutably good is no point of imperfection, but the height of perfection.

4. As God is unchangeable in regard of essence, knowledge, purpose,so he is unchangeable in regard of place. He cannot be changed in time, because he is eternity; so he cannot be changed in place, because he hath ubiquity: he is eternal, therefore cannot be changed in time; he is omnipresent, therefore cannot be changed in place: he doth not begin to be in one place wherein he was not before, or cease to be in a place wherein he was before. He that fills every place in heaven and earth, cannot change place; he cannot leave one to possess another, that is equally, in regard of his essence, in all: “He fills heaven and earth” (Jer. xxiii. 24). The heavens that are not subject to those changes to which sublunary bodies are subject, that are not diminished in quantity or quality; yet they are alway changing place in regard of their motion; no part of them doth alway continue in the same point: but God hath no change of his nature, because he is most inward in everything; he is substantially in all spaces, real and imaginary; there is no part of the world which he doth not fill; no place can be imagined wherein he doth not exist. Suppose a million of worlds above and about this, encircling one another; his essence would be in every part and point of those worlds; because it is indivisible, it cannot be divided; nor can it be contained within those created limits of millions of worlds, when the most soaring and best coining fancy hath run through all creatures to the highest sphere of the heavens, and imagined one world after another, till it can fancy no more: none of these, nor all of these, can contain God; for the “heaven of heavens cannot contain him” (1 Kings viii. 27); “He is higher than heaven, deeper than hell” (Job xi. 8), and possesses infinite imaginary spaces beyond created limits.He who hath no cause of being, can have no limits of being;[604] and though by creation he began to be in the world, yet he did not begin to be where the world is, but was in the same imaginary space from all eternity; for he was alway in himself by his own eternal ubi. Therefore observe, that when God is said to draw near to us when we draw near to him (James iv. 8), it is not by local motion or change of place, but by special and spiritual influences, by exciting and supporting grace. As we ordinarily say, the sun is come into the house when yet it remains in its place and order in the heavens, because the beams pierce through the windows and enlighten the room, so when God is said to come down or descend (Gen. xi. 5; Exod. xxxiv. 5), it is not by a change of place, but a change of outward acts, when he puts forth himself in ways of fresh mercy or new judgments, in the effluxes of his love or the flames of his wrath. When good men feel the warm beams of his grace refreshing them, or wicked men feel the hot coals of his anger scorching them.God’s drawing near to us is not so much his coming to us, but his drawing us to him;[605] as when watermen pull a rope that is in one end fastened to the shore, and the other end to the vessel; the shore is immovable, yet it seems to the eye to come to them, but they really move to the shore. God is an immovable rock; we are floating and uncertain creatures; while he seems to approach to us, he doth really make us to approach to him; he comes not to us byany change of place himself, but draws us to him by a change of mind, will, and affections in us.
