When Jesus spoke again to the people, he said, "I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life."
Put your trust in the light while you have it, so that you may become sons of light.
But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sins.
1 John 1:7
You are the light of the world. A city on a hill cannot be hidden.
