John 1: 1,4,5 ESV
“In the beginning was the Word, and the Word was with God, and the Word was God…In him (Jesus) was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it.”
As Jesus is the light, and we receive that light as our Savior, we too become the light to a dark world…the darkness will NOT overcome that light in us.
