John 1:4, 9, 14, 18

In him was life, and that life was the light of all mankind.

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

The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth.

No one has ever seen God, but the one and only Son, who is himself God and is in closest relationship with the Father, has made him known.
