This little light is not mine

 John himself was not the light; he was simply a witness to tell about the light.  The one who is the true light, who gives light to everyone, was coming into the world. John 1:8-9

Being the light is too big a responsibility, far beyond the nature and scope of the human soul. Human beings reflect the light of Christ. By the inspiration of His Spirit we are part of His light-giving presence in the world,  but the light does not originate in us.

Lord, be Sun to my moon; shine through the dark places that still lurk in me that others might see Your light.
