Christ is represented by the sun. Malachi 4:2 tells us, “But to you who fear My name the Sun of Righteousness shall arise with healing in His wings…”
God’s truth is represented by light. John 1:1-5 states, “In the beginning was the Word [Jesus Christ], and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him, and without Him nothing was made that was made. In Him was life, and the life was the light of men. And the light shines in the darkness, and the darkness did not comprehend it.”
We are to be lights to the world, as Matt. 5:14-16 instructs: “You are the light of the world. A city that is set on a hill cannot be hidden. Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house. Let your light so shine before men, that they may see your good works and glorify your Father in heaven.”
Therefore we reflect God’s light. The moon does not produce its own light but merely reflects the light of the sun. Likewise God’s people, first ancient Israel and more recently the body of Christ, reflect the light of Christ. When the moon is full, it is as if many people are reflecting the light of Christ by their actions. The Harvest Moon, the full moon at its largest, occurs at the time of the Feast of Tabernacles, which pictures the future time when everyone will be living God’s way. When you see the Harvest Moon, think about what a joyous time it will be when everybody is reflecting God’s light.
