John 1:9, 8:12, 9:5, 12:35-36. 46

The true light, which gives light to everyone, was coming into the world.

Again Jesus spoke to them, saying, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.

As long as I am in the world, I am the light of the world.”

So Jesus said to them, “The light is among you for a little while longer. Walk while you have the light, lest darkness overtake you. The one who walks in the darkness does not know where he is going. While you have the light, believe in the light, that you may become sons of light.” When Jesus had said these things, he departed and hid himself from them.

“I have come into the world as light, so that whoever believes in me may not remain in darkness.” (ESV)
