The Divine needs to connect with what's been created, especially to what is human. Since the Divine Itself is, in its essence, beyond human comprehension, we can see and know it from its visible forms which are the Word, Jesus Christ, the created universe, and even the the human mind and body. These and many other things express the Divine Human.

To understand this further, imagine that you are completely paralyzed, to the point that you can’t make a sound or even move your eyes or the muscles of your face. Someone you love walks up to you. Inside, you feel a surge of affection. But how can you show it? You can’t say it, can’t smile, can’t even form an expression in your eyes. It can’t be done; you have no communication at all.

To be expressed, then, love needs a vessel, something capable of communication. That vessel is what Swedenborg calls the “human.”

For us, in the physical world, that “human” is in the form of our physical bodies. Through them we can smile, laugh, speak, hug, kiss, write - and can also strike out, shout in anger and criticize. Our bodies are the vessels that let us share what’s inside with the people around us. Through our bodies we also see, hear and feel the things inside others. They are the mode through which we interact.

But imagine if you could read minds, and could allow your mind to be read by others. You would no longer need your body as a vessel, but the things you shared would still be human; they would be human thoughts, human feelings, human ideas, still distinctly your own and reflective of the kind of person you are. You’d still have a “human,” but it would be your mind instead of your body.

That can give us some idea of what the Lord’s “human” is: it is the vessel through which we can receive His love and His guidance. It’s not something physical, like our human bodies, but is spiritual, as our minds are spiritual. And it puts His love into feelings, images and ideas, just as our minds do.

Put that way, it’s easy to see that the Lord’s humanity has always been, and was indeed an agent of creation: in creating the universe, the Lord used his human to give form to His love, forms that would be separate from Him, forms that He could love. It’s also easy to see that His humanity will always be: He is love itself, and that love will always need a vessel.

The Lord’s “human” also fills another great need. We are finite; the Lord is infinite. We live in a world of dead physical matter; the Lord is life itself. We are born into selfish loves; the Lord loves us infinitely. We live in time and space and can only think in terms of time and space; the Lord is outside of time and space, uncontained and uncontainable. For these and many other reasons the Lord, in His essence, is inconceivable to us; we have no mental tools to form an idea of the infinite. We can, however, think of the Lord as a human, and can thus worship him in the form of His divine human. By relating his love to us, his humanity makes it possible for us to relate to Him.

That leaves one great question: what about Jesus? He was human, but also kind of God, too. How does that relate to the idea of the divine human?

The answer lies in how we receive what the Lord gives us, and how that reception has changed over the millennia.

The Lord’s love is conveyed to us through the divine human in the form of what Swedenborg calls “divine truth,” which is essentially the Lord’s thoughts, His ideas. These thoughts are, of course, all about love, and are filled to overflowing with His love.

The earliest people, those of what Swedenborg calls the “Most Ancient Church,” could receive those thoughts directly, and accept the love in them directly. From this they were pure and innocent to a degree we can barely imagine, with wisdom and insight that sprang from the love they shared.

As people drew away from the Lord, though, their ability to accept the love contained within the divine truth began to degrade. In what Swedenborg calls the “Ancient Church” people received it in the form of love of one another, and accessed it through powerfully symbolic stories and the symbolism of nature. Finally, with the Children of Israel, the love and the truth were almost completely separated, with the Lord’s ideas contained within ritual, but His inspiration to be good operating in a disconnected way. Ultimately those people grew so evil that the desire for good was in danger of being choked off forever.

So the Lord rendered his “human” into physical flesh, born as a child to the virgin Mary. As always, that human was a vessel for the Lord’s love, but it was a vessel that could share divine truth in a tangible way. Swedenborg’s works say that Jesus spent his life stripping away His mortal aspects by battling temptations, and was a form of divine truth when He began His ministry. During His ministry he stripped away his mortal loves, until in the final temptation on the cross he was fully reunited with the divine love that was His soul. In His ministry, then, he shared His deepest ideas, and in His death He shared the love that formed and filled those ideas. It was enough to save humankind forever.

In doing this the Lord also changed His relationship with us. He gave us deeper truths about how to be loving, and taught us that love is more important than ritual. He also opened for us the idea that the Bible is full of deeper and richer meanings: that it is itself a form of divine truth. With these tools we now have the ability to use the Lord’s ideas as a key to accept His love. By knowing what’s right, knowing what the Lord teaches, we can compel ourselves to act in loving ways even if we don’t feel the love, and the Lord will use that to reform us so that we come to actually love what is good.

So the Divine Human is still a vessel for the Lord’s love, as it has always been. It’s a vessel that has adapted according to our needs and the paths the Lord can use to draw us toward heaven.

151. These things saith the Son of man. That this signifies the Lord as to the Divine Human, from which is that constituent of the church, is evident from the signification of the Son of God, as denoting the Lord as to His Divine Human, and as to Divine truth, inasmuch as the latter proceeds from Him (concerning which see above, n. 63). That it also denotes from whom is that constituent of the church, that is, the opening of the internal or spiritual man and its conjunction with the external, is, that everything of the church pertaining to man is from the Lord's Divine Human. For everything of love and faith constituting the church proceeds from the Divine Human of the Lord, and not immediately from the Divine itself; for what immediately proceeds from the Divine itself does not enter into any thought or affection of man, and consequently not into faith and love, because it is far above them, as is evident from the fact that a man cannot think of the Divine without connecting with such thought the human form, unless he thinks of nature, as it were, in its minutest parts. The thought which is not directed to some particular form is diffused in all directions, and what is thus diffused is dissipated. This it has been specially granted me to know, from those in the other life who come from the Christian world, and who have thought only of the Father, and not of the Lord, that they make nature in its minutest parts their God, and at length fall away from any idea of God, consequently from the idea and faith of all things of heaven and the church.

[2] It is different with those who have thought of God in the human form; all these have their ideas directed to the Divine, nor do their thoughts, like those of the former, wander in every direction. And, inasmuch as the Divine under a human form, is the Divine Human of the Lord, therefore the Lord bends and determines their thoughts and affections to Himself. Because this is the essential of the church, therefore it continually flows in from heaven with man, consequently it is, as it were, implanted in every one to think of the Divine under a human form, and thus inwardly in themselves to see the Divine, except in the case of those who have extinguished this impression in themselves (as may be seen in the work, Heaven and Hell 82). It is therefore evident why all men after death, however vast their number, when they become spirits, are turned to their own loves, and that hence those who have worshipped the Divine under the human form turn to the Lord, who is seen by them as a Sun above the heavens. But those who have not worshipped Him under the human form are turned to the loves of their own natural man, all of which have reference to the loves of self and of the world; thus they turn backwards from the Lord; and to turn themselves backwards from the Lord, is to turn towards hell. (That all turn themselves to their own loves in the spiritual world, may be seen in the work, Heaven and Hell 17, 123, 142-145, 151, 153, 255, 272, 510, 548, 552, 561.

[3] All those who lived in ancient times, and worshipped the Divine, saw the Divine, in thought, under a human form, and scarcely any one thought of an invisible Divine; and the Divine under the human form, even at that time, was the Divine Human. But because this Divine Human was the Lord's Divine in the heavens and passing through the heavens, when heaven became weakened for the reason that men, of whom heaven consists, from internal became successively external, and thus natural, it therefore pleased the Divine Himself to put on the Human, and to glorify this, 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 save those who acknowledge and worship His Divine in the Human.

[4] This is manifest from many passages in the Prophets of the Old Testament, and also in the Evangelists, from which we shall adduce 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 by him, and without him was not anything made that was made. In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not. That was the true light, which lighteth every man that cometh into the world. He was in the world, and the world knew him not. And the Word was made flesh, and dwelt among us, and we beheld his glory" (1:1-14).

That the Lord as to the Human is there meant by the Word, is quite clear, for it is said, "the Word was made flesh, and dwelt among us, and we beheld his glory;" and that the Lord made His Human Divine, is also plain from these words, "the Word was with God, and God was the Word," and this was made flesh, that is, man. And whereas all Divine truth proceeds from the Divine Human of the Lord, and this is His Divine in the heavens, therefore by the Word is also signified Divine truth; and it is said, He was the true light which lighteth every man that cometh into the world. Light also is Divine truth; and because men, from being internal, became external or natural, because they no longer acknowledged Divine truth, or the Lord, therefore it is said that the darkness comprehended not the light, and that the world acknowledged Him not. (That the Word is the Lord as to the Divine Human, and Divine truth thence proceeding, may be seen in The Doctrine of the New Jerusalem 263 and 304. That light is Divine truth, and that darkness denotes the falsities in which those are who are not in the light, may be seen in the work, Heaven and Hell 126-140, 275.)

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

"As many as received him, to them gave he power to become the sons of God, 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 (vir), but of God" (1:12, 13).

Those who are born of bloods, are those who destroy love and charity; the will of the flesh denotes all evil derived from the loves of self and of the world, and is man's voluntary proprium, which in itself is nothing but evil; the will of man is falsity derived from that voluntary proprium. That those who are not in these loves receive the Lord, are regenerated and saved, is meant by them that believe in His name becoming the sons of God, and being born of God. (That to believe in the name of the Lord, is to acknowledge His Divine Human, and to receive from Him love and faith, may be seen above, n. 102, 135. That bloods denote those things that destroy love and charity, see Arcana Coelestia 4735, 5476, 9127: that flesh denotes the voluntary proprium of man, which in itself is nothing but evil, n. 210, 215, 731, 874-876, 987, 1047, 2307, 2308, 3518, 3701, 3812, 4328, 8480, 8550, 10283-10286, 10731; and that man's proprium is the love of self and the love of the world, n. 694, 731, 4317, 5660. That man (vir) denotes the Intellectual, and hence truth or falsity, because the Intellectual is from the one or the other, see n. 3134, 3309, 9007, thus the will of man (vir) denotes the intellectual proprium, which, when it exists from the voluntary proprium, which in itself is nothing but evil, is nothing but falsity; for where evil is in the will there falsity is in the understanding. That to be born of God is to be regenerated by the Lord, may be seen inThe Doctrine of the New Jerusalem 173-184. Moreover, that all in the universe, from influx out of heaven, and from revelation, worship the Divine under the human form, may be seen in the small work, The Earths in the Universe 98, 121, 141, 154, 158, 159, 169; and likewise all the angels of the higher heavens, in the work, Heaven and Hell 78-86.)

[6] From these considerations it is now evident that the all of the church, thus also the all of heaven pertaining to men, is from the Lord's Divine Human. It is on this account that the Son of Man, who is the Divine Human, is described, in the first chapter of the Apocalypse, by various representatives, and afterwards from that description are taken the exhortations to the several churches (as may be seen above, n. 113), and specifically to this church, in writing to which this great essential of the church is treated of, that is, 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 man, who hath his eyes like unto a flame of fire."
