Commentaries
1:14-19 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.
Ge 1:14-19. Fourth Day.
14. let there be lights in the firmament—The atmosphere being completely purified, the sun, moon, and stars were for the first time unveiled in all their glory in the cloudless sky; and they are described as "in the firmament" which to the eye they appear to be, though we know they are really at vast distances from it.
