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 bore witness about him, and cried out, “This was he of whom I said, ‘He who comes after me ranks before me, because he was before me.’”) For from his fullness we have all received, grace upon grace. For the law was given through Moses; grace and truth came through Jesus Christ. No one has ever seen God; the only God, who is at the Father’s side, he has made him known.
John 1:14-18 (ESV)
John 1:14-18 proclaims the identity of Jesus in two complimentary ways. Jesus is Deity distinct from the Father, yet equal to and worthy to be called the one true God. Jesus was a real human being who enter our world as Emmanuel, God with us. The mission of Jesus was to bring grace: the unmerited, abundant favor and forgiveness of God to those who believe in Him.
