English: King James Version -
This is a key moment in this story. The beginning of John 1 explained that the Lord is perfect, infinite love which gave itself expression as divine truth. The duality of love and expression formed a template for humanity, which meant that the Lord’s duality made him the ultimate, divine human. It showed that the divine truth was the power of creation, and that the Lord shared that truth with humanity from the outset, so that people could receive His love and return it. But people kept turning away, and the Lord had to keep expressing his love in more and more external forms to maintain a connection.
By mentioning John the Baptist, the chapter showed that the Jews of the time still had the truth – the Lord’s Word – contained inside the rough-hewn images of the Old Testament. But they were so steeped in evil loves and false thinking that the connection to the Word – to the love within the Old Testament – was about to be snipped forever.
So the Word became flesh. The Lord passed the full expression of His love and His full humanity into physical flesh as Jesus. That way He could once again show the life within the existing Scriptures and could make His own life and His own words part of an expanded expression of truth for a new age of humanity. People could no longer see and feel the Lord’s love through the Old Testament, but they could see and feel it in the face and hands and words of Jesus.
The "glory" here expresses the blinding brilliance of that truth. The "Father" represents the Lord’s actual love itself, and being "begotten" means that the love was expressed in the form of truth. Being full of "truth" has a pretty obvious meaning, but "grace" means an affection, a love for what is true.
The Lord had to come. He had to let His humanity flow down into the flesh, into the most external of forms, because that was the only way we were going to see and embrace it.
