3 And God said, Let there be light: and there was light.   4 And God saw the light, that it was good: and God divided the light from the darkness.   5 And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

      We have here a further account of the first day's work, in which observe, 1. That the first of all visible beings which God created was light; not that by it he himself might see to work (for the darkness and light are both alike to him), but that by it we might see his works and his glory in them, and might work our works while it is day. The works of Satan and his servants are works of darkness; but he that doeth truth, and doeth good, cometh to the light, and coveteth it, that his deeds may be made manifest, John iii. 21. Light is the great beauty and blessing of the universe. Like the first-born, it does, of all visible beings, most resemble its great Parent in purity and power, brightness and beneficence; it is of great affinity with a spirit, and is next to it; though by it we see other things, and are sure that it is, yet we know not its nature, nor can describe what it is, or by what way the light is parted, Job xxxviii. 19, 24. By the sight of it let us be led to, and assisted in, the believing contemplation of him who is light, infinite and eternal light (1 John i. 5), and the Father of lights (Jam. i. 17), and who dwells in inaccessible light, 1 Tim. vi. 16. In the new creation, the first thing wrought in the soul is light: the blessed Spirit captives the will and affections by enlightening the understanding, so coming into the heart by the door, like the good shepherd whose own the sheep are, while sin and Satan, like thieves and robbers, climb up some other way. Those that by sin were darkness by grace become light in the world. 2. That the light was made by the word of God's power. He said, Let there be light; he willed and appointed it, and it was done immediately: there was light, such a copy as exactly answered the original idea in the Eternal Mind. O the power of the word of God! He spoke, and it was done, done really, effectually, and for perpetuity, not in show only, and to serve a present turn, for he commanded, and it stood fast: with him it was dictum, factum--a word, and a world. The world of God (that is, his will and the good pleasure of it) is quick and powerful. Christ is the Word, the essential eternal Word, and by him the light was produced, for in him was light, and he is the true light, the light of the world, John i. 9; ix. 5.. The divine light which shines in sanctified souls is wrought by the power of God, the power of his word and of the Spirit of wisdom and revelation, opening the understanding, scattering the mists of ignorance and mistake, and giving the knowledge of the glory of God in the face of Christ, as at first, God commanded the light to shine out of darkness, 2 Cor. iv. 6. Darkness would have been perpetually upon the face of fallen man if the Son of God had not come, and given us an understanding, 1 John v. 20. 3. That the light which God willed, when it was produced, he approved of: God saw the light that it was good. It was exactly as he designed it, and it was fit to answer the end for which he designed it. It was useful and profitable; the world, which now is a palace, would have been a dungeon without it. It was amiable and pleasant. Truly the light is sweet (Eccl. xi. 7); it rejoiceth the heart, Prov. xv. 30. What God commands he will approve and graciously accept; he will be well pleased with the work of his own hands. That is good indeed which is so in the sight of God, for he sees not as man sees. If the light is good, how good is he that is the fountain of light, from whom we receive it, and to whom we owe all praise for it and all the services we do by it! 4. That God divided the light from the darkness, so put them asunder as that they could never be joined together, or reconciled; for what fellowship has light with darkness? 2 Cor. vi. 14. And yet he divided time between them, the day for light and the night for darkness, in a constant and regular succession to each other. Though the darkness was now scattered by the light, yet it was not condemned to a perpetual banishment, but takes its turn with the light, and has its place, because it has its use; for, as the light of the morning befriends the business of the day, so the shadows of the evening befriend the repose of the night, and draw the curtains about us, that we may sleep the better. See Job vii. 2. God has thus divided time between light and darkness, because he would daily remind us that this is a world of mixtures and changes. In heaven there is perfect and perpetual light, and no darkness at all; in hell, utter darkness, and no gleam of light. In that world between these two there is a great gulf fixed; but, in this world, they are counterchanged, and we pass daily from one to another, that we may learn to expect the like vicissitudes in the providence of God, peace and trouble, joy and sorrow, and may set the one over-against the other, accommodating ourselves to both as we do to the light and darkness, bidding both welcome, and making the best of both. 5. That God divided them from each other by distinguishing names: He called the light day, and the darkness he called night. He gave them names, as the Lord of both; for the day is his, the night also is his, Ps. lxxiv. 16. He is the Lord of time, and will be so, till day and night shall come to an end, and the stream of time be swallowed up in the ocean of eternity. Let us acknowledge God in the constant succession of day and night, and consecrate both to his honour, by working for him every day and resting in him every night, and meditating in his law day and night. 6. That this was the first day's work, and a good day's work it was. The evening and the morning were the first day. The darkness of the evening was before the light of the morning, that it might serve for a foil to it, to set it off, and make it shine the brighter. This was not only the first day of the world, but the first day of the week. I observe it to the honour of that day, because the new world began on the first day of the week likewise, in the resurrection of Christ, as the light of the world, early in the morning. In him the day-spring from on high has visited the world; and happy are we, for ever happy, if that day-star arise in our hearts.

      14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:   15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.   16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.   17 And God set them in the firmament of the heaven to give light upon the earth,   18 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.   19 And the evening and the morning were the fourth day.

      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 xxvi. 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, v. 14, 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 (v. 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 (Luke viii. 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. xii. 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, Eccl. iii. 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, Matt. xvi. 2, 3. They do also give light upon the earth, that we may walk (John xi. 9), and work (John ix. 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! Ps. viii. 3, 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, Matt. v. 14. We burn our Master's candles, but do not mind our Master's work.

      II. In particular, v. 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 Ps. xix. 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, Matt. xx. 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 (v. 16, 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 Ps. cxxxvi. 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. xxxi. 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 Deut. iv. 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.
