“And God saith, `Let luminaries be in the expanse of the heavens, to make a separation between the day and the night, then they have been for signs, and for seasons, and for days and years, and they have been for luminaries in the expanse of the heavens to give light upon the earth:’ and it is so.
And God maketh the two great luminaries, the great luminary for the rule of the day, and the small luminary — and the stars — for the rule of the night; and God giveth them in the expanse of the heavens to give light upon the earth, and to rule over day and over night,
and to make a separation between the light and the darkness; and God seeth that [it is] good; and there is an evening, and there is a morning — day fourth.
Genesis 1 : 14 – 19 ( Young’s Literal Translation )
“In the fourth day’s work, the creation of the sun, moon, and stars is accounted for. All these are the works of God.
The stars are spoken of as they appear to our eyes, without telling their number, nature, place, size, or motions; for the Scriptures were written, not to gratify curiosity, or make us astronomers, but to lead us to God, and make us saints.
The lights of heaven are made to serve him; they do it faithfully, and shine in their season without fail. We are set as lights in this world to serve God; but do we in like manner answer the end of our creation?
We do not: our light does not shine before God, as his lights shine before us. We burn our Master’s candles, but do not mind our Master’s work.”
