John 1:4-9

In him was life, and that life was the light of all mankind. The light shines in the darkness, and the darkness has not overcome it. There was a man sent from God whose name was John. He came as a witness to testify concerning that light, so that through him all might believe. He himself was not the light; he came only as a witness to the light. The true light that gives light to everyone was coming into the world.
