Prop. II. This spiritual worship of God is manifest by the light of nature, to be due to him. In reference to this, consider,
1. The outward means or matter of that worship which would be acceptable to God, was not known by the light of nature. The law for a worship, and for a spiritual worship by the faculties of our souls was natural, and part of the law of creation; though the determination of the particular acts, whereby God would have this homage testified, was of positive institution, and depended not upon the law of creation. Though Adam in innocence knew God was to be worshipped, yet by nature he did not know by what outward acts he was to pay this respect, or at what time he was more solemnly to be exercised in it than at another: this depended upon the directions God, as the sovereign Governor and Lawgiver, should prescribe. You therefore find the positive institutions of the “tree of the knowledge of good and evil,” and the determination of the time of worship (Gen. ii. 3, 17). Had there been any such notion in Adam naturally, as strong as that other, that a worship was due to God, there would have been found some relics of these modes universally consented to by mankind, as well as of the other. But though all nations have by an universal consent concurred in the acknowledgment of the being of God, and his right to adoration, and the obligation of the creature to it; and that there ought to be some public rule and polity in matters of religion (for no nation hath been in the world without a worship, and without external acts and certain ceremonies to signify that worship); yet their modes and rites have been as various as their climates, unless in that common notion of sacrifices, not descending to them by nature, but tradition from Adam; and the various ways of worship have been more provoking than pleasing. Every nation suited the kind of worship to their particular ends and polities they designed to rule by. How God was to be worshipped is more difficult to be discerned by nature with its eyes out than with its eyes clear.423 The pillars upon which the worship of God stands cannot be discerned without revelation, no more than blind Samson could tell where the pillars of the Philistines’ theatre stood, without one to conduct him. What Adam could not see with his sound eyes, we cannot with our dim eyes; he must be told from heaven what worship was fit for the God of heaven. It is not by nature that we can have such a full prospect of God as may content and quiet us; this is the noble effect of Divine revelation; He only knows himself, and can only make himself known to us. It could not be supposed that an infinite God should have no perfections but what were visible in the works of his hands; and that these perfections should not be infinitely greater, than as they were sensible in their present effects: this had been to apprehend God a limited Being, meaner than he is. Now it is impossible to honor God as we ought, unless we know him as he is; and we could not know him as he is, without divine revelation from himself; for none but God can acquaint us with his own nature: and therefore the nations void of this conduct, heaped up modes of worship from their own imaginations, unworthy of the majesty of God, and below the nature of man. A rational man would scarce have owned such for signs of honor, as the Scripture mentions in the services of Baal and Dagon; much less an infinitely wise and glorious God. And when God had signified his mind to his own people, how unwilling were they to rest satisfied with God’s determination, but would be warping to their own inventions, and make gods, and ways of worship to themselves!424 as in the matter of the golden calf, as was lately spoken of.
2. Though the outward manner of worship acceptable to God could not be known without revelation, and those revelations might be various; yet the inward manner of worship with our spirits was manifest by nature: and not only manifest by nature to Adam in innocence, but after his fall, and the scales he had brought upon his understanding by that fall. When God gave him his positive institutions before the fall, or whatsoever additions God should have made, had he persisted in that state; or, when he appointed him, after his fall, to testify his acknowledgment of him by sacrifices, there needed no command to him to make those acknowledgments by those outward ways prescribed to him, with the intention and prime affection of his spirit: this nature would instruct him in without revelation; for he could not possibly have any semblance of reason to think that the offering of beasts, or the presenting the first fruits of the increase of the ground, as an acknowledgment of God’s sovereignty over him and his bounty to him, was sufficient, without devoting to him that part wherein the image of his Creator did consist: he could not but discern, by a reflection upon his own being, that he was made for God as well as by God: for it is a natural principle of which the apostle speaks (Rom. xi. 36), “For of him, and through him, and to him are all things,” &c.: that the whole whereof he did consist was due to God; and that his body, the dreggy and dusty part of his nature, was not fit to be brought alone before God, without that nobler principle, which he had, by creation, linked with it. Nothing in the whole law of nature, as it is informed of religion, was clearer, next to the being of a God, than this manner of worshipping God with the mind and spirit. And as the Gentiles never sunk so low into the mud of idolatry, as to think the images they worshipped were really their gods, but the representations, or habitations of their gods; so they never deserted this principle in the notion of it, that God was to be honored with the best they were, and the best they had: as they never denied the being of a God in the notion, though they did in the practice, so they never rejected this principle in notion, though they did, and now most men do, in the inward observation of it: it was a maxim among them that God was mens animus, mind and spirit, and therefore was to be honored with the mind and spirit: that religion did not consist in the ceremonies of the body, but the work of the soul; whence the speech of one of them: “Sacrifice to the gods, not so much clothed with purple garments as a pure heart:”425 and of another: “God regards not the multitude of the sacrifices, but the disposition of the sacrificer.”426 It is not fit we should deny God the cream and the flower, and give him the flotten part and the stalks. And with what reverence and intention of mind they thought their worship was to be performed, is evident by the priests crying out often, Hoc age, Mind this, let your spirits be intent upon it. This could not but result,
(1.) From the knowledge of ourselves. It is a natural principle, “God hath made us, and not we ourselves” (Psalm c. 1, 2). Man knows himself to be a rational creature; as a creature he was to serve his Creator, and as a rational creature with the best part of that rational nature he derived from him. By the same act of reason that he knows himself to be a creature, he knows himself to have a Creator; that this Creator is more excellent than himself, and that an honor is due from him to the Creator for framing of him; and, therefore, this honor was to be offered to him by the most excellent part which was framed by him. Man cannot consider himself as a thinking, understanding, being, but he must know that he must give God the honor of his thoughts, and worship him with those faculties whereby he thinks, wills, and acts.427 He must know his faculties were given him to act, and to act for the glory of that God who gave him his soul, and the faculties of it; and he could not in reason think they must be only active in his own service, and the service of the creature, and idle and unprofitable in the service of his Creator. With the same powers of our soul, whereby we contemplate God, we must also worship God; we cannot think of him but with our minds, nor love him but with our will; and we cannot worship him without the acts of thinking and loving, and therefore cannot worship him without the exercise of our inward faculties: how is it possible then for any man that knows his own nature, to think that extended hands, bended knees, and lifted up eyes, were sufficient acts of worship, without a quickened and active spirit?
(2.) From the knowledge of God. As there was a knowledge of God by nature, so the same nature did dictate to man, that God was to be glorified as God; the apostle implies the inference in the charge he brings against them for neglecting it.428 “We should speak of God as he is,” said one;429 and the same reason would inform them that they were to act towards God as he is. The excellency of the object required a worship according
