God made two big lights, the larger to take charge of Day, The smaller to be in charge of Night; and he made the stars. God placed them in the heavenly sky to light up Earth And oversee Day and Night, to separate light and dark. God saw that it was good. - Genesis 16:18
The sun is the source of all light.
The moon is simply a reflection of that light.
It cannot shine on its own.
The moon reflects the sun only when the earth is not in the way.
I believe the relationship between the sun and moon are symbols of God's purpose for your life and mine.
Think about it: God IS light. He is the source of all illumination. There is no light apart from Him. There is no darkness where He is, and darkness has absolutely no power over Him.
On the other hand, the moon possesses no light of its own. It is only a reflection of the sun. The only reason we can see the moon is because the sun makes it possible.
Here's where I'm going: Just as the moon reflects the light of the sun, so we reflect the true-light of God. We cannot shine apart from Him. We also cannot reflect Him when the things of earth (worry, doubt, fear, regret, anger, prejudice, greed, lust, etc.) stand between us and God.
If we turn our faces to God and set our eyes on Jesus, those around us will see His reflection. They may not recognize the reflection but they will know something is different about us.
Allow me to challenge you: Every morning, for the next week--when you wake--turn your heart to the face of God. Before you even put your feet on the floor, let a prayer of gratitude be the first words to leave your lips. Then before you turn on the news, open Facebook or Instagram, turn to a verse of Scripture and let them be the first words you read.
Position yourself to be the reflection of God you were designed to be. Then, go and be light in someone else's darkness.
