John 1:4, 9, 14, 18

In him was life, and the life was the light of men.

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

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.

No one has ever seen God; the only God, who is at the Father’s side, he has made him known.
