We could say the Lord’s love “has always been and will always be,” but even that really doesn’t cover it – the Lord is beyond time, and in fact time came from Him. We could say that Lord’s love is expressed “everywhere and in everything,” but even that really doesn’t cover it – the Lord is beyond both space and the stuff that fills space, and in fact space and stuff both came from Him.

So the Lord’s love never changes: It simply is. And the expression of that love – what the Writings call “divine truth” – never changes: It simply is.

People, on the other hand, change all the time, both as individuals and as societies. We turn toward the Lord and toward each other; we turn away from the Lord and away from each other. We look to spiritual things; we look to bodily things. That means our reception of the Lord’s love changes all the time, and the Lord’s love, in its complete desire to be joined to us, adapts its external forms constantly to try to reach us.

That’s what’s described here, in John 1:6-18. Humankind had always received the divine truth, but the forms had become more external as people got more external. Among the earliest, most innocent people The Lord could flow in directly; later he reached people through the minds, using symbolic stories and nature as a container. As people became entirely external, however, His love flowed out in the stony form of the laws of Moses. Understood spiritually, these laws and the other stories and prophecies of the Old Testament contain infinite ideas about the Lord and connections to His love – they contain all of the divine truth. But the Children of Israel themselves couldn’t understand that; the best they could do was obey.

That historic process is described in verses 9-13, which show the creative and sustaining power of divine truth (represented by both “the Light” and “the Word”), as well as the fact that those who received it became “sons of God,” or angels in heaven. As time went on, though, most people “received him not” and “knew him not.” In fact, as the Jewish leaders twisted the externals of Scripture to their own selfish ends, the world grew so evil that according to the Writings humanity was in danger of losing its connection to the Lord altogether.

So “the Word” – divine truth, the expression of the Lord’s love – was “made flesh” in the form of Jesus. In a way, this was the most external form the divine truth could take, extending from spiritual reality to give itself a physical form. But the purpose was to turn the process around: Jesus would reveal the deeper meanings of Scripture and teach the divine truth more directly, through commandments of love and caring. He would start humanity on a spiritual journey back toward a more internal life, one more receptive of the Lord’s love.

So what’s the role of John the Baptist here? John represents the external, literal meaning of the Old Testament, and to “witness” means to confirm what is good by using the things we know to be true. So John here witnesses first to “the light,” reminding the people of the time that Scripture is holy and urging them to return to its forms; and later to Jesus, confirming through the letter of Scripture that he was the promised Messiah, come to offer us truth and grace – which represents the delight we feel in things that are true – and ultimately to “declare” the Father to us, or to bring us into connection with the love that is the Lord’s essence.

(References: The Apocalypse Explained 151:4, 294 [16])

151. These things saith the Son of man, signifies the Lord in respect to the Divine Human, from which is that essential of the church. This is evident from the signification of "the Son of man," as being the Lord in respect to the Divine Human, and in respect to Divine truth, since Divine truth proceeds from Him (See above, n. 63); also as being that from which is that essential of the church, namely, the opening of the internal or spiritual man, and the conjunction thereof with the external, since everything of the church with man is from the Lord's Divine Human. For everything of love and faith, which two constitute the church, proceeds from the Lord's Divine Human, and not immediately from the Divine Itself; for what proceeds immediately from His Divine Itself, does not fall into any thought and affection of man, nor consequently into faith and love, because it is far above them. This can be seen from the fact that man is not able to think of the Divine Itself apart from the human form, except as he thinks of nature, as it were, in things least. Thought that is not determined to a certain figure is diffused in every direction, and what is diffused is dissipated. This has been given me to know most especially from those in the other life who are from the Christian world, who have thought only of the Father, and not of the Lord, that they make nature in its minutest parts their God, and finally fall away from all idea of God, consequently from the idea and faith in anything of heaven and the church.

[2] It is otherwise with those who have thought of God under the human form; these have all their ideas determined to the Divine, nor do their thoughts, like the thoughts of those mentioned before, wander in every direction. And as the Divine under the Human form, is the Lord's Divine Human, therefore the Lord bends and determines their thoughts and affections to Himself. This, because it is the primary truth of the church, unceasingly flows in out of heaven with man; consequently it is, as it were, implanted in everyone to think of the Divine under the human form, and thus to see His Divine inwardly in himself, with the exception of such as have extinguished in themselves this implanted thought (See in the work on Heaven and Hell 82). From this the reason can also be seen, why all men, whatsoever after death, when they become spirits, turn themselves to their own loves, and thus why those who have worshiped the Divine under the human form turn themselves to the Lord, who appears to them as a sun above the heavens. But those who have not worshiped the Divine under the human form, turn themselves to the loves of their natural man, all of which have reference to the loves of self and the world, thus turning backwards from the Lord; and turning oneself backwards from the Lord is turning towards hell. (That all in the spiritual world turn themselves to their own loves, see in the work on Heaven and Hell 17, 123, 142-145, 151, 153, 255, 272, 510, 548, 552, 561).

[3] All who lived in ancient times and worshiped the Divine saw the Divine in thought under the human form, and hardly anyone thought of an invisible Divine; and the Divine under the human form was even then the Divine Human. But as this Divine Human was the Divine of the Lord in the heavens and passing through the heavens, when at length heaven became enfeebled, because men, of whom heaven is made up, from internal successively became external and thus natural, therefore it pleased the Divine Itself to put on a human, and to glorify it, or make it Divine, that thus from Himself He might affect all, both those who are in the spiritual world and those who are in the natural world, and might save those who acknowledge and worship His Divine in the Human.

[4] This is clearly stated in many passages in the Old Testament Prophets, as well as in the Evangelists; of these I will cite only the following in John:

In the beginning was the Word, and the Word was with God, and God was the Word. All things were made through Him, and without Him was not anything made that hath been made. In Him was life; and the life was the light of men. And that Light shineth in the darkness; and the darkness apprehended it not. It was the true Light, which lighteth every man coming into the world. He was in the world, but the world acknowledged Him not. And the Word became flesh, and dwelt among us, and we beheld His glory (John 1:1-14).

It is plainly evident that the Lord in respect to the Human is here meant by "the Word," for it is said, "the Word became flesh, and dwelt among us, and we beheld His glory." It is also evident that the Lord made His Human to be Divine, for it is said, "the Word was with God and God was the Word, and this became flesh," that is, a man. And since all Divine truth proceeds from the Lord's Divine Human, and this is His Divine in the heavens, therefore by "the Word" is also signified Divine truth; and thence He is said to be "the Light which lighted every man coming into the world." Moreover, "light" is Divine truth; and because men from being internal became so external or natural as no longer to acknowledge Divine truth or the Lord, therefore it is said that "the darkness apprehended not the light," and that "the world acknowledged Him not." (That the Word is the Lord in respect to the Divine Human and Divine truth proceeding therefrom, see The Doctrine of the New Jerusalem 263, 304. That "light" is Divine truth, and "darkness" the falsities in which those are who are not in the light, see in the work on Heaven and Hell 126-140, 275.)

[5] That they who acknowledge the Lord and worship Him from love and faith, and are not in the love of self and the love of the world, are regenerated and saved, is also taught in these words in John:

As many as received Him, to them gave He power to be children of God, even to them that believe in His name; which were born, not of bloods, nor of the will of the flesh, nor of the will of man, but of God (John 1:12, 13).

Here "of bloods" means such as destroy love and charity. "The will of the flesh" is every evil from the love of self and love of the world, also man's will-proprium, which in itself is nothing but evil; "the will of man" is falsity thence that comes from that will-proprium. That those who are not in these loves receive the Lord and are regenerated and saved, is meant by its being said that those who "believe in His name become children of God," and are "born of God."

(That to "believe in the Lord's name" is to acknowledge His Divine Human and to receive love and faith from Him, see above. n. 102, 135.

That "bloods" are the things that destroy love and charity, see Arcana Coelestia 4735, 5476, 9127; that "flesh" is man's will-proprium, which in itself is nothing but evil, n. 210, 215, 731, 874-876, 987, 1047, 2307, 2308, 3518, 3701, 3812, 4328, 8480, 8550, 10283, 10284, 10286, 10732; and that man's proprium is the love of self and the love of the world, n. 694, 731, 4317, 5660.

That "man" [vir] is the intellectual, and therefore truth or falsity, since the intellectual is of the one or the other, see n. 3134, 3309, 9007.

Thus "the will of man" [viri] is the intelligence-proprium, which, when it exists from the will-proprium [which in itself is nothing but evil], is nothing but falsity, for where evil is in the will there is falsity in the understanding.

That to be "born of God" is to be regenerated by the Lord, see The Doctrine of the New Jerusalem 173-184.

Moreover, that all in the universe, from influx out of heaven and from revelation, worship the Divine in the human form, see Earths in the Universe 98, 121, 141, 154, 158, 159, 169; likewise all angels of the higher heavens, see in the work on Heaven and Hell 78-86.)

[6] From this it can now be seen that everything of the church, thus also everything of heaven with men, is from the Lord's Divine Human. For this reason "the Son of man," who is the Divine Human, is described in the first chapter of Revelation by various representatives; and from that description the introductory sentences to each of the churches are taken (as may be seen above, n. 113, and what is said to this church in particular treats of this chief essential of the church, namely, the conjunction of the internal and external, or the regeneration of the man of the church; for it is said to the angel of this church, "These things saith the Son of God, that hath His eyes as a flame of fire."
