"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" (John 1:14).
"The Word," as John 1:1 reminds us, is God himself, the Logos (the Greek word translated "Word"), who always was eternally God, not created. The Trinity has always existed, and the Word is the second person of the Trinity. He is infinite, eternal, and unchangeable.
God the Word came down as flesh in the person of Jesus and walked on the earth He had created.
1 Timothy 3:16
And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory. (KJV)
