There was a man sent from God, whose name was John. He came as a witness, to bear witness about the light, that all might believe through him. He was not the light, but came to bear witness about the light.

The true light, which gives light to everyone, was coming into the world. He was in the world, and the world was made through him, yet the world did not know him. He came to his own, and his own people did not receive him. But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh
nor of the will of man, but of God.
John 1:6-13

God, Who made the sun, also made the moon.
The moon does not take away from the brilliance of the sun.
The moon would be only a burnt-out cinder floating in the immensity of space were it not for the sun. All its light is reflected from the sun. On dark nights we are grateful for the moon; when we see it shining, we know there must be a sun. So in this dark night of the world when men turn their backs on Him Who is the Light of the World, we … await the sunrise.
~Archbishop Fulton Sheen from The World’s First Love

John the Baptist was clear: he was a witness to the True Light Jesus, not the light himself.

He reflected the origin of light, like the moon reflects the sun.

We are naturally wary of prophets, not knowing who to believe and who leads us astray. God warns us about false prophets, yet we have difficulty discerning truth, so turn our backs to it, missing the Light.

Instead, when I see moonlight, I try to remember the message of John the Baptist: seeing the moon glow reminds me the Sun is the true origin of Light. And so as God’s children, we are to reflect the Light as well, bearing witness in the darkness.

I am reading slowly through the words in the Book of John over the next year. At the beginning of each week, I will invite you to “come and see” what those words might mean as we explore His promises together.
