God saw that the light was good. The darkness that before did cover the face of the waters, was not a creature of God, but a privation, or that which was caused by reason that light was not as yet in the world: so sin, that darkness that might be felt, is not the workmanship of God in the soul, but that which is the work of the devil; and that taketh occasion to be, by reason that the true light, as yet, doth not shine in the soul.
"And God divided the light from the darkness." As Paul saith, What communion hath light with darkness? they cannot agree to dwell together (2 Cor 6:14). We see the night still flies before the day, and dareth not come upon us again, but as the light diminisheth and conveyeth itself away. So it is in the new creation; before the light of the glorious gospel of Christ appears, there is night, all night, in the soul (Eph 5:8): but when that indeed doth shine in the soul, then for night there is day in the soul: "Ye were darkness [saith Paul] but now are ye light in the Lord" (v 9): And, "The darkness is past [saith John] and the true light now shineth" (1 John 2:8).
"And God divided the light from the darkness."
God took part with the light, and preserved it from the darkness. By these words, it seems that darkness and light began the quarrel, before that bloody bout of Cain and Abel (Gal 5:17). The light and the darkness struggled together, and nothing could divide or part them but God. Darkness is at implacable enmity with light in the creation of the world; and so it is in that rare work of regeneration, the flesh lusteth against the spirit, and the spirit against the flesh; as Peter saith, Fleshly lusts, they war against the soul. This every Christian feels, and also that which I mentioned before, namely, That before he be capable of opposing antichrist, with Abel, in the world, he findeth a struggling in his own soul between the light and the darkness that is there.
"And God called the light Day, and the darkness he called Night."
God doth not only distinguish by separating, but also by certain characters; that things which are distinguished and separate, may to us be the better known; he did so here in the work of creating the world, and he doth so also in the great concern of man's eternal happiness. The place of felicity is called heaven: The place of torment is called hell: that which leads to hell is called sin, transgression, iniquity, and wickedness; that which leads to heaven, righteousness, holiness, goodness and uprightness: even as in these types God called the light day, of which the godly are the children (1 Thess 5:5); but the darkness he called night, of which all ungodly men are the inhabiters and children also. Thus after the Spirit of God had moved upon the face of the waters; after God had commanded the light to shine, and had divided between the light and the darkness, and had characterized them by their proper names, he concludes the first day's work, "And the evening and the morning were the first day." In which conclusion there is wrapped up a blessed gospel-mystery; for God, by concluding the first day here, doth shew us how we ought to determine that one is made indeed a Christian: Even then when the Spirit of God hath moved upon the face of the heart, when he hath commanded that light should be there, when he divideth between, or setteth the light at variance with the darkness; and when the soul doth receive the characters of both, to observe them, and carry it to each according to the mouth of God.
"And God saith, Let there be a firmament" (v 6).
This firmament he calleth heaven (v 8). Now this firmament, or heaven, was to make a separation, or to divide between the waters and the waters (v 7); To separate, I say, the waters from the waters; the waters which were under the firmament, from the waters which were above the firmament. Now by waters is signified in the scriptures many things, as afflictions, worldly people (Psa 69:1,2), and particularly the saints (Rev 19:6); but in this place is figured forth, all the people in the world, but so as consisting of two parts, the children of God, and the children of the wicked one: They under the heaven, figure out the world, or ungodly: they above the firmament, the elect and chosen of God. And hence in scripture the one is called heaven, and the other is called earth, to signify the separation and difference that there is between the one and the other.
"And God made the firmament, and divided the waters—from the waters."
Indeed the world think that this separation comes, or is made, through the captiousness of the preacher: But in truth it is the handy work of God; And God made the firmament, and God divided, &c. "I," saith he, "will put enmity between thee and the woman, and between thy seed and her seed" (Gen 3:15). The good seed are the children of the kingdom of God, but the bad are the children of the wicked one (Matt 13:38).
