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 between the light and the darkness. 5 And God called the light Day, and the darkness he called Night. And there was evening, and there was morning—the first day.

6 And God said, Let there be an expanse in the midst of the waters, and let it be a division between waters and waters. 7 And God made the expanse, and divided between the waters that are under the expanse and the waters that are above the expanse; and it was so. 8 And God called the expanse Heavens. And there was evening, and there was morning—a second day.

9 And God said, Let the waters under the heavens be gathered together to one place, and let the dry [land] appear. And it was so. 10 And God called the dry [land] Earth, and the gathering together of the waters he called Seas. And God saw that it was good.

Commentary on Genesis 1:3-5

(Read Genesis 1:3-5)

God said, Let there be light; he willed it, and at once there was light. Oh, the power of the word of God! And in the new creation, the first thing that is wrought in the soul is light: the blessed Spirit works upon the will and affections by enlightening the understanding. Those who by sin were darkness, by grace become light in the Lord. Darkness would have been always upon fallen man, if the Son of God had not come and given us understanding, 1 John 5:20. The light which God willed, he approved of. God divided the light from the darkness; for what fellowship has light with darkness? In heaven there is perfect light, and no darkness at all; in hell, utter darkness, and no gleam of light. The day and the night are the Lord's; let us use both to his honour, by working for him every day, and resting in him every night, meditating in his law both day and night.

Commentary on Genesis 1:6-13

(Read Genesis 1:6-13)

The earth was emptiness, but by a word spoken, it became full of God's riches, and his they are still. Though the use of them is allowed to man, they are from God, and to his service and honour they must be used. The earth, at his command, brings forth grass, herbs, and fruits. God must have the glory of all the benefit we receive from the produce of the earth. If we have, through grace, an interest in Him who is the Fountain, we may rejoice in him when the streams of temporal mercies are dried up.
