This is the history of the fourth day's work, the creating of the sun, moon, and stars, which are here accounted for, not as they are in themselves and in their own nature, to satisfy the curious, but as they are in relation to this earth, to which they serve as lights; and this is enough to furnish us with matter for praise and thanksgiving. Holy Job mentions this as an instance of the glorious power of God, that by the Spirit he hath garnished the heavens (Job 26:13); and here we have an account of that garniture which is not only so much the beauty of the upper world, but so much the blessing of this lower; for though heaven is high, yet has it respect to this earth, and therefore should have respect from it. Of the creation of the lights of heaven we have an account,

I.In general, Gen 1:14, Gen 1:15, where we have 1. The command given concerning them: Let there be lights in the firmament of heaven. God had said, Let there be light (Gen 1:3), and there was light; but this was, as it were, a chaos of light, scattered and confused: now it was collected and modelled, and made into several luminaries, and so rendered both more glorious and more serviceable. God is the God of order, and not of confusion; and, as he is light, so he is the Father and former of lights. Those lights were to be in the firmament of heaven, that vast expanse which encloses the earth, and is conspicuous to all; for no man, when he has lighted a candle, puts it under a bushel, but on a candlestick (Luk 8:16), and a stately golden candlestick the firmament of heaven is, from which these candles give light to all that are in the house. The firmament itself is spoken of as having a brightness of its own (Dan 12:3), but this was not sufficient to give light to the earth; and perhaps for this reason it is not expressly said of the second day's work, in which the firmament was made, that it was good, because, till it was adorned with these lights on the fourth day, it had not become serviceable to man. 2. The use they were intended to be of to this earth. (1.) They must be for the distinction of times, of day and night, summer and winter, which are interchanged by the motion of the sun, whose rising makes day, his setting night, his approach towards our tropic summer, his recess to the other winter: and thus, under the sun, there is a season to every purpose, Ecc 3:1. (2.) They must be for the direction of actions. They are for signs of the change of weather, that the husbandman may order his affairs with discretion, foreseeing, by the face of the sky, when second causes have begun to work, whether it will be fair or foul, Mat 16:2, Mat 16:3. They do also give light upon the earth, that we may walk (Joh 11:9), and work (Joh 9:4), according as the duty of every day requires. The lights of heaven do not shine for themselves, nor for the world of spirits above, who need them not; but they shine for us, for our pleasure and advantage. Lord, what is man, that he should be thus regarded! Psa 8:3, Psa 8:4. How ungrateful and inexcusable are we, if, when God has set up these lights for us to work by, we sleep, or play, or trifle away the time of business, and neglect the great work we were sent into the world about! The lights of heaven are made to serve us, and they do it faithfully, and shine in their season, without fail: but we are set as lights in this world to serve God; and do we in like manner answer the end of our creation? No, we do not, our light does not shine before God as his lights shine before us, Mat 5:14. We burn our Master's candles, but do not mind our Master's work.

II.In particular, Gen 1:16-18.

1.Observe, The lights of heaven are the sun, moon, and stars; and all these are the work of God's hands. (1.) The sun is the greatest light of all, more than a million times greater than the earth, and the most glorious and useful of all the lamps of heaven, a noble instance of the Creator's wisdom, power, and goodness, and an invaluable blessing to the creatures of this lower world. Let us learn from Psa 19:1-6 how to give unto God the glory due unto his name, as the Maker of the sun. (2.) The moon is a less light, and yet is here reckoned one of the greater lights, because though, in regard to its magnitude and borrowed light, it is inferior to many of the stars, yet, by virtue of its office, as ruler of the night, and in respect of its usefulness to the earth, it is more excellent than they. Those are most valuable that are most serviceable; and those are the greater lights, not that have the best gifts, but that humbly and faithfully do the most good with them. Whosoever will be great among you, let him be your minister, Mat 20:26. (3.) He made the stars also, which are here spoken of as they appear to vulgar eyes, without distinguishing between the planets and the fixed stars, or accounting for their number, nature, place, magnitude, motions, or influences; for the scriptures were written, not to gratify our curiosity and make us astronomers, but to lead us to God, and make us saints. Now these lights are said to rule (Gen 1:16, Gen 1:18); not that they have a supreme dominion, as God has, but they are deputy-governors, rulers under him. Here the less light, the moon, is said to rule the night; but in Psa 136:9 the stars are mentioned as sharers in that government; The moon and stars to rule by night. No more is meant than that they give light, Jer 31:35. The best and most honourable way of ruling is by giving light and doing good: those command respect that live a useful life, and so shine as lights.

2.Learn from all this, (1.) The sin and folly of that ancient idolatry, the worshipping of the sun, moon, and stars, which, some think, took rise, or countenance at least, from some broken traditions in the patriarchal age concerning the rule and dominion of the lights of heaven. But the account here given of them plainly shows that they are both God's creatures and man's servants; and therefore it is both a great affront to God and a great reproach to ourselves to make deities of them and give them divine honours. See Deu 4:19. (2.) The duty and wisdom of daily worshipping that God who made all these things, and made them to be that to us which they are. The revolutions of the day and night oblige us to offer the solemn sacrifice of prayer and praise every morning and evening.

And God made two great lights - Moses speaks of the sun and moon here, not according to their bulk or solid contents, but according to the proportion of light they shed on the earth. The expression has been cavilled at by some who are as devoid of mental capacity as of candour. "The moon," say they, "is not a great body; on the contrary, it is the very smallest in our system." Well, and has Moses said the contrary? He has said it is a great Light; had he said otherwise he had not spoken the truth. It is, in reference to the earth, next to the sun himself, the greatest light in the solar system; and so true is it that the moon is a great light, that it affords more light to the earth than all the planets in the solar system, and all the innumerable stars in the vault of heaven, put together. It is worthy of remark that on the fourth day of the creation the sun was formed, and then "first tried his beams athwart the gloom profound;" and that at the conclusion of the fourth millenary from the creation, according to the Hebrew, the Sun of righteousness shone upon the world, as deeply sunk in that mental darkness produced by sin as the ancient world was, while teeming darkness held the dominion, till the sun was created as the dispenser of light. What would the natural world be without the sun? A howling waste, in which neither animal nor vegetable life could possibly be sustained. And what would the moral world be without Jesus Christ, and the light of his word and Spirit? Just what those parts of it now are where his light has not yet shone: "dark places of the earth, filled with the habitations of cruelty," where error prevails without end, and superstition, engendering false hopes and false fears, degrades and debases the mind of man.

Many have supposed that the days of the creation answer to so many thousands of years; and that as God created all in six days, and rested the seventh, so the world shall last six thousand years, and the seventh shall be the eternal rest that remains for the people of God. To this conclusion they have been led by these words of the apostle, Pe2 3:8 : One day is with the Lord as a thousand years; and a thousand years as one day. Secret things belong to God; those that are revealed to us and our children.

He made the stars also - Or rather, He made the lesser light, with the stars, to rule the night. See Claudlan de Raptu Proser., lib. ii., v. 44.

Hic Hyperionis solem de semine nasci Fecerat,

et pariter lunam, sed dispare forma, Aurorae noctisque duces.

From famed Hyperion did he cause to rise

The sun, and placed the moon amid the skies,

With splendor robed, but far unequal light,

The radiant leaders of the day and night.

Of the Sun

On the nature of the sun there have been various conjectures. It was long thought that he was a vast globe of fire 1,384,462 times larger than the earth, and that he was continually emitting from his body innumerable millions of fiery particles, which, being extremely divided, answered for the purpose of light and heat without occasioning any ignition or burning, except when collected in the focus of a convex lens or burning glass.

Against this opinion, however, many serious and weighty objections have been made; and it has been so pressed with difficulties that philosophers have been obliged to look for a theory less repugnant to nature and probability. Dr. Herschel's discoveries by means of his immensely magnifying telescopes, have, by the general consent of philosophers, added a new habitable world to our system, which is the Sun. Without stopping to enter into detail, which would be improper here, it is sufficient to say that these discoveries tend to prove that what we call the sun is only the atmosphere of that luminary; "that this atmosphere consists of various elastic fluids that are more or less lucid and transparent; that as the clouds belonging to our earth are probably decompositions of some of the elastic fluids belonging to the atmosphere itself, so we may suppose that in the vast atmosphere of the sun, similar decompositions may take place, but with this difference, that the decompositions of the elastic fluids of the sun are of a phosphoric nature, and are attended by lucid appearances, by giving out light." The body of the sun he considers as hidden generally from us by means of this luminous atmosphere, but what are called the maculae or spots on the sun are real openings in this atmosphere, through which the opaque body of the sun becomes visible; that this atmosphere itself is not fiery nor hot, but is the instrument which God designed to act on the caloric or latent heat; and that heat is only produced by the solar light acting upon and combining with the caloric or matter of fire contained in the air, and other substances which are heated by it. This ingenious theory is supported by many plausible reasons and illustrations, which may be seen in the paper he read before the Royal Society. On this subject see the note on Gen 1:3.

Of the Moon

There is scarcely any doubt now remaining in the philosophical world that the moon is a habitable globe. The most accurate observations that have been made with the most powerful telescopes have confirmed the opinion. The moon seems, in almost every respect, to be a body similar to our earth; to have its surface diversified by hill and dale, mountains and valleys, rivers, lakes, and seas. And there is the fullest evidence that our earth serves as a moon to the moon herself, differing only in this, that as the earth's surface is thirteen times larger than the moon's, so the moon receives from the earth a light thirteen times greater in splendor than that which she imparts to us; and by a very correct analogy we are led to infer that all the planets and their satellites, or attendant moons, are inhabited, for matter seems only to exist for the sake of intelligent beings.

Of the Stars

The Stars in general are considered to be suns, similar to that in our system, each having an appropriate number of planets moving round it; and, as these stars are innumerable, consequently there are innumerable worlds, all dependent on the power, protection, and providence of God. Where the stars are in great abundance, Dr. Herschel supposes they form primaries and secondaries, i.e., suns revolving about suns, as planets revolve about the sun in our system. He considers that this must be the case in what is called the milky way, the stars being there in prodigious quantity. Of this he gives the following proof: On August 22,1792, he found that in forty-one minutes of time not less than 258,000 stars had passed through the field of view in his telescope. What must God be, who has made, governs, and supports so many worlds! See Clarke's note on Gen 1:1.

And God set them in the firmament of the heaven,.... He not only ordered that there they should be, and made them that there they might be, but he placed them there with his own hands; and they are placed, particularly the sun, at such a particular distance as to be beneficial and not hurtful: had it been set nearer to the earth, its heat would have been intolerable; and had it been further off it would have been of no use; in the one case we should have been scorched with its heat, and in the other been frozen up for the want of it. The various expressions used seem to be designed on purpose to guard against and expose the vanity of the worship of the sun and moon; which being visible, and of such great influence and usefulness to the earth, were the first the Heathens paid adoration to, and was as early as the times of Job, Job 31:26 and yet these were but creatures made by God, his servants and agents under him, and therefore to worship them was to serve the creature besides the Creator,

To give light upon the earth; this is repeated from Gen 1:15 to show the end for which they were made, and set up, and the use they were to be of to the earth; being hung up like so many lamps or chandeliers, to contain and send forth light unto the earth, to the inhabitants of it, that they may see to walk and work by, and do all the business of life, as well as be warmed and comforted thereby, and the earth made fertile to bring forth its precious fruits for the use of creatures in it: and it is marvellous that such light should be emitted from the sun, when it is at such a vast distance from the earth, and should reach it in so short a space. A modern astronomer (m) observes, that a bullet discharged from a cannon would be near twenty five years, before it could finish its journey from the sun to the earth: and yet the rays of light reach the earth in seven minutes and a half, and are said to pass ten millions of miles in a minute.

two great lights--In consequence of the day being reckoned as commencing at sunset--the moon, which would be seen first in the horizon, would appear "a great light," compared with the little twinkling stars; while its pale benign radiance would be eclipsed by the dazzling splendor of the sun; when his resplendent orb rose in the morning and gradually attained its meridian blaze of glory, it would appear "the greater light" that ruled the day. Both these lights may be said to be "made" on the fourth day--not created, indeed, for it is a different word that is here used, but constituted, appointed to the important and necessary office of serving as luminaries to the world, and regulating by their motions and their influence the progress and divisions of time.
