Isaiah 9:2 "The people who walked in darkness have seen a great light; those who dwelt in a land of deep darkness, on them has light shined.:
John 1:4-5, 14 "In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it. And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth."
