Charles Spurgeon Commentary Genesis 1:14-19

"And God said, Let there be lights in the firmament of heaven to divide the day from the night; and let them be for signs, and for seasons, and for days and years: and let them be for lights in the firmament of heaven to give light upon the earth: and it was so. And God made the two great lights; the greater light to rule the day, and the lesser light to rule the night: [he made] the stars also. And God set them in the firmament of heaven to give light upon the earth, 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. And there was evening and there was morning, a fourth day." — Genesis 1:14-19 (ASV)

Whether the sun and moon are here said to be absolutely created, or whether they were only created as far as our planet was concerned by the dense vapors being cleared away so that the sun, moon, and stars could be seen, is a matter of no consequence at all to us. Let us rather learn a lesson from them. These lights are to rule, but they are to rule by giving light. And, brothers, this is the true rule in the Church of God.

He who gives most light is the truest ruler. The man who aspires to leadership in the Church of God, if he knows what he is doing, aspires to be the servant of all by devoting himself to the good of all, even as our Savior said to his disciples, Whosoever of you will be the chiefest, shall be servant of all. The sun and moon are the servants of all humankind, and therefore they rule by day and by night. Stoop, my brothers, if you wish to lead others. The way up is downward. To be great, you must be little. He is the greatest who is nothing at all to himself, but all for others.
