In the 61st chapter of Isaiah, there is a beautiful prophecy of the Lord's advent, and of the impact that it would have. It begins this way:

“The Spirit of the Lord God is upon Me, Because the Lord has anointed Me To preach good tidings to the poor; He has sent Me to heal the brokenhearted.... (Isaiah 61:1)

In the New Testament, in Luke 4:14-22, we see confirmation of this prophecy, in this story:

"14 And Jesus returned in the power of the Spirit into Galilee: and there went out a fame of him through all the region round about.

15 And he taught in their synagogues, being glorified of all.

16 And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read.

17 And there was delivered unto him the book of the prophet Esaias. And when he had opened the book, he found the place where it was written,

18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised,

19 To preach the acceptable year of the Lord.

20 And he closed the book, and he gave it again to the minister, and sat down. And the eyes of all them that were in the synagogue were fastened on him.

21 And he began to say unto them, This day is this scripture fulfilled in your ears.

22 And all bare him witness, and wondered at the gracious words which proceeded out of his mouth. And they said, Is not this Joseph's son?"

In this passage, who are the poor, and the brokenhearted? They are people who do not yet know enough real truth, or who therefore are not yet able to receive real good. They are people who "are ignorant of truth and who desire it." (Inner Meaning of the Prophets and Psalms 61).

Here's another source:

"These things (above) are said of the Lord. 'The poor' to whom Jehovah has anointed Him to preach good tidings, refers to those who are in few truths, and yet desire truths that their soul may be sustained by them. The 'broken in heart' stand for those who as a consequence are in grief." (Apocalypse Explained 811[17]).

Every person has two spiritual faculties that work together -- a will (the things we love), and an understanding (the things we know and believe in). We're born with both, and they gradually develop. Our original will is mostly selfish, and it needs to be gradually expunged, and replaced by a new unselfish will that the Lord wants to implant and develop in us. On our personal spiritual journeys, that's the the big thing that needs to happen.

Our understanding, at some points in that process, needs to step out ahead of the will, and learn true ideas, and construct them into a framework. There has to be a part of the will that directs the understanding to make this effort, and wants to use the framework. There's another part of the will that says -- no, not interested, don't bother, maybe later. But it's the unselfish part - the good part - that feels this driving need for truth. It's people who are in this state that are poor (needing to learn truth), and brokenhearted (in grief, and therefore wanting to learn truth, so that they can be good, and receive the Lord's love). See Arcana Coelestia 6854[3] and its related cross-references for an interesting discussion of this process.

5114. 'And on the vine three shoots' means derivatives from this even to the final one. This is clear from the meaning of 'the vine' as the understanding part, dealt with immediately above in 5113; from the meaning of 'three' as complete and continuous even to the end, dealt with in 2788, 4495; and from the meaning of 'shoots' as derivatives; for since 'the vine' means the understanding part, 'shoots' means nothing else than derivatives from this. Because 'three' means that which is continuous even to the end, that is, which goes from first to last, 'three shoots' means derivative degrees extending from the understanding part to the final level, which is that of the senses. The first in the sequence is the actual understanding part, and the last is the senses. In general the understanding part is the sight which the internal man possesses and which sees by the light of heaven radiating from the Lord; and everything it sees is spiritual or celestial. But the senses, in general, belong to the external man; and here the sensory power of sight is meant because this corresponds to and is subordinate to the understanding part. The sensory power of sight sees by the light of the world radiating from the sun; and everything it sees is worldly, bodily, or earthly.

[2] In the human being there exist derivatives from the understanding part that dwells in the light of heaven; and they extend to the senses which dwell in the light of the world. Unless these derivatives existed the senses could not possess any life of a human quality. A person does not owe the life which his senses possess to what he sees by the light of the world, for the light of the world holds no life within it; he owes it to what he sees by the light of heaven, for this light does hold life within it. When the light of heaven falls on the perceptions a person has gained by the light of the world, it brings life to them and enables him to see objects in an intelligent manner, and thus as a human being. In this way a person possessing factual knowledge born from things which he has seen and heard in the world, and therefore from those which have entered in through the senses, comes to possess intelligence and wisdom, on which in turn he bases his public, private, and spiritual life.

[3] As regards derivatives specifically, the nature of their existence in a person is such that no brief explanation of them is possible. They exist as degrees, like steps, from the understanding part down to the senses. But no one can have any conception of those degrees unless he knows how they are related to one another, that is to say, that they are quite distinct and separate from one another, so distinct that interior degrees can come into being and remain in being without exterior ones, but not exterior degrees without interior ones. For example, a person's spirit can remain in being without a material body, as it also actually does when death separates it from the body. For a person's spirit exists in an interior degree, his body in an exterior one. Similarly with a person's spirit after death. If he is one of the blessed his spirit exists in a final and outermost degree when in the first heaven; in a more interior degree when in the second; and in the inmost one when in the third. When it exists in the inmost it exists at the same time in the other degrees, though these are inactive with him, almost as the human body is inactive during sleep, but with this difference that interiorly angels are at such times fully awake. Therefore as many distinct and separate degrees exist in the human being as there are heavens, apart from the final one, which is the body and the bodily senses.

[4] From all this regarding a person's spirit one may gain some idea of the way derivatives are related to one another from the first to the final one, that is, from the understanding part to the senses. A person's life, which he receives from the Lord's Divine, passes through these degrees from the inmost to the final one. At every degree there exists a derivative of that life which becomes increasingly general, until in the final degree it is the most general. Derivatives in the lower degrees are merely combinations - or to put it more appropriately, structured forms - of the individual and particular constituents of the higher degrees ranged consecutively, with the addition of the kinds of things drawn from purer nature, and after that from grosser nature, that can serve as containing vessels. Once these vessels are done away with, the individual and particular constituents of the higher degrees, which had received form in those vessels, move back to the degree immediately above. And because in the case of the human being there is a link with the Divine, and his inmost being is such that it can accept the Divine - and not only accept but also make Him its own, by acknowledging and having an affection for the Divine, thus by a reciprocal response to Him - and because he thereby has the Divine implanted within him, he can never die. Indeed what is eternal and infinite exists with him, not only through their flowing into him but also through his reception of them.

[5] From this one may see how uninformed and senseless in their thinking regarding the human being those people are who compare him to animals and imagine that he will not be alive after death any more than they are. Such people do not take into consideration the fact that with animals there is no acceptance of the Divine or any acknowledgement or affection leading to a reciprocal response to the Divine by making Him their own, or any consequent joining to Him. Nor do those people take into consideration the fact that, as the animal state is like this, the recipient forms of life which these possess are inevitably dissipated; for with animals that which flows into them passes through their organic forms into the world, where it comes to an end and melts away, never to make any return there.
