The best depiction of this has been painted onto the canvas of creation in the Sun and moon. The Sun is infinitely greater than the moon, the Sun creates light and brings life, while the moon neither creates nor brings about anything apart from the sun. The moon simply testifies to the existence of something infinitely greater, that which is its source. Simply put the Moon is meant to "bear the image" or "Reflect the image" of the sun and Testify even when it appears as though the sun if no longer visible (ie. At Night). If the moon could fail to do this(I realize it does not have much of a choice), it would not mean that the sun does not exist. For example in a lunar eclipse the moon does not reflect the radiance of the Sun, but the Sun is still every bit as illuminating and brilliant.
We were created to bear his image and reflect his light, just as the moon reflects the light of the Sun. We are in darkness without the Light of God. So it is with the moon, who is unable to illumine anything apart from the Sun's light shining on it.
Today we have the choice to either be "image bearers" of God and shine HIS light, to be the "light of the world" or to not. Our participation his little to do with whether he will continue to shine, it will only affect whether or not we "enlighten" the world and testify that something greater gives us our source of Light. Or we will simply continue to tolerate the darkness, and fail "to proclaim the excellencies of him who called us out of darkness and into his marvelous light".
Will we declare today? Will you be an "image bearer" and reflect his marvelous light or be content with dwelling in the darkness?
-Give us your Grace oh God, we need you...
