Lights of the Seasons

Genesis 1:14 says that God allowed the “lights in the expanse of the sky to separate the day from the night” and to serve as “signs to mark seasons and days and years.” We can call them the lights of the seasons.

Although light is essential for our existence, the Sun, Moon, and stars are intended to serve an additional purpose. In Genesis 1:1 God created the heavens and the Earth. “Heavens,” or “shamayim” in the original Hebrew, would include the Sun, Moon, and stars. Genesis 1:14 tells us that God lifted the cloud cover (described in Genesis 1:2 and Job 38:9) so that the heavenly lights could be clearly seen to establish the circadian rhythm, give us a way to determine directions, and allow us to mark the passage of time.

Today (December 21) is the time when the Sun reaches its lowest point in the sky. In the Northern Hemisphere, it is the shortest daylight and marks the first day of winter. In the Southern Hemisphere, it is the most extended daylight which marks the first day of summer. We call it the winter or summer solstice. The word “solstice” comes from two Latin words meaning “sun” and “stand still” because on this day the Sun appears to momentarily stop its southward journey and start back toward the north. (The opposite is true on June 21.)

When Earth has made one complete rotation on its axis, the Sun’s position shows us that one day of 24 hours has passed. When the Earth completes one revolution around the Sun (approximately 365 days), we can see that the Sun has finished one cycle of its apparent north-south swing. We know that one year has passed.

It’s the 23.4-degree tilt of Earth’s axis with respect to the Sun that causes us to have seasons as our planet makes its year-long solar revolution. That tilt makes it appear that the Sun is moving north and south through the sky each year and gives us seasons. Without seasons, only limited areas of Earth would be habitable. Without day and night, one half of the Earth would be baking in the sunshine while the other half would be continually cold and dark. When the Moon has made one revolution around Earth, we can see that it has completed all of its phases and we know that one lunar (or synodic) month has passed.

As we consider these lights of the seasons, keep one thing in mind. When Moses recorded the words of Genesis, people didn’t understand what caused “seasons, days, and years.” Now we do. We can see the full meaning of Genesis 1:14 when God opened the sky to reveal the lights of the seasons. Moses accurately recorded what God revealed to him, but he didn’t understand it. Science allows us to know how God did what He did. We believe that is what science is all about – discovering how God did it. True science and a correct understanding of the Bible are in complete agreement because God is the author of both.
