John 1:1-5

1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was with God in the beginning. 3 Through him all things were made; without him nothing was made that has been made. 4 In him was life, and that life was the light of all mankind. 5 The light shines in the darkness, and the darkness has not overcome it.

John 8:12

12 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.
