3 And God said, Let there be light: and there was light. 4 And God, looking on the light, saw that it was good: and God made a division between the light and the dark, 5 Naming the light, Day, and the dark, Night. And there was evening and there was morning, the first day.

6 And God said, Let there be a solid arch stretching over the waters, parting the waters from the waters. 7 And God made the arch for a division between the waters which were under the arch and those which were over it: and it was so. 8 And God gave the arch the name of Heaven. And there was evening and there was morning, the second day.

9 And God said, Let the waters under the heaven come together in one place, and let the dry land be seen: and it was so. 10 And God gave the dry land the name of Earth; and the waters together in their place were named 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.
