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.

2. We can see clearly that the specific Word meant here is the Word made known through Moses, the prophets, and the evangelists, since this is the actual divine truth from which angels get all their wisdom and from which we get our spiritual intelligence. In fact, angels in the heavens have the very same Word that we have in the world, though for us in the world it is earthly, while in the heavens it is spiritual. Further, since it is divine truth, the Word is also something divine that is emanating, and this is not only from the Lord but is the Lord himself.

Since it is the Lord himself, absolutely everything written in the Word is about the Lord alone. From Isaiah to Malachi every detail has to do with the Lord, either directly or in an opposite, negative sense.

No one has seen this before, but anyone who knows this and thinks of it can see it while reading, especially given the knowledge that in the Word there is not only an earthly meaning but a spiritual one as well; and that in this latter meaning the names of persons and places are used to mean something about the Lord and therefore something about heaven and the church that come from him-or something opposed to the Lord.

Since absolutely everything in the Word is about the Lord, and since the Word is the Lord because it is divine truth, we can see why it says “The Word became flesh and lived among us; and we saw his glory” [John 1:14]. We can also see why it says “While you have the light, believe in the light, so that you may become children of the light. I have come into the world as a light; anyone who believes in me will not remain in darkness” [John 12:36, 46]. “Light” is divine truth and therefore the Word.

For this reason, even nowadays anyone who turns to the Lord alone while reading the Word and who prays to him will find enlightenment in it.
