Commentary - John 1:14

14 And the Word was made flesh, and dwelled among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.

Perhaps the most important single statement in the entire New Testament. “The word (God) became flesh, and dwelled among us...” John’s metaphor states the parameters of God’s intervention. Jesus came into the world as a human being, no more and no less with the same feelings, emotions and energy that you and I experience when things go right or wrong or in any one of the thousands of variations that come along every day including all forms of diversion and temptation.
Another point that must be made is that according to John, Jesus brought with him into this world no supernatural power whatsoever. Jesus came as human flesh. Most Christian theology proclaims that Jesus came as a God Man, fully God and fully man. John said that Jesus came as a man.

In the second part of this verse, John acknowledges that a distinct difference does exist between the begotten son of the Living God and those of us who are the sons of mere humans. As we proceed through the book, many of these differences will become apparent. John's reference here to “grace” and “truth” reflect John’s admiration for Jesus’ style and appearance. Jesus must truly have been a striking individual with remarkable mental clarity.
