John 1:4, 9, 14, 18

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

That was the true Light which gives light to every man coming into the world.

And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.

No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has declared Him.
