The Word Became Flesh

What does it mean that Jesus was God and Man?

John 1:1-3 ESV

In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made.

John 1:14 ESV

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.
