14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: 15 and let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. 16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. 17 And God set them in the firmament of the heaven to give light upon the earth, 18 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. 19 And the evening and the morning were the fourth day.
Dear children, today we shall learn about God’s creative works on the fourth day of Creation – He made two great lights and the stars (v. 16), and “set them in the firmament of the heaven” (v. 17).
The two great lights are the sun and the moon. They are to be “for signs, and for seasons, and for days, and years” (v. 14). In other words, they were created to be a measurement of time. Time can be measured by the cycles of the rising and setting of the sun, whereby one day is delineated by one cycle of “evening and morning”. 365 such days make up one solar year.
In the Old Testament, we see God used time to tell His people of things that will happen in the future. For example, He told Abraham that Sarah would give birth to Isaac “at this set time in the next year” (Genesis 17:21). When God’s appointed time came, Sarah gave birth to a baby boy, and His prophecy was fulfilled.
The two great lights, together with the stars, were set in the galaxy to “give light upon the earth” (v. 15, 17) as well. The “greater light” (i.e. the sun) is to rule the day while the “lesser light” (i.e. the moon) is to rule the night. So, man receives sunlight during the day to guide him in his work and life on earth, whereas in the night, he has the sun’s reflected
light via the moon (together with the stars) to guide him around. These physical lights, while acting as luminaries in the sky, also serve as a spiritual visual guide which silently point to their Maker, the LORD God Almighty.
My young readers, whenever you walk around during the day or in the night, you ought to appreciate these lights that God has given to man. Therefore, let us thank Him for these wonderful creations, without which we cannot measure time nor find
our way around during the day or night.
