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.

6854. 'And I have come down to deliver them from the hand of the Egyptians' means that He would stoop down to them to release them from the power of false factual knowledge, which tries to destroy the truths of the Church. This is clear from the meaning of 'coming down' as stooping down, dealt with below; from the meaning of 'to deliver' as to release, for one who releases people from falsities delivers or sets them free; from the meaning of 'the hand' as the power, dealt with in 878, 3387, 3563, 4931-4937, 5544; and from the meaning of 'the Egyptians' as false factual knowledge, which is opposed to the Church's truths, dealt with in 6651, 6679, 6683, and so which tries to destroy them. As regards the Lord's coming down, the situation is that the Lord is said to come or stoop down when He comes to judgement, 1311, and also when He comes down to lower things, in this instance to those belonging to the spiritual Church, who are meant by 'the children of Israel'. For the subject in the internal sense is the way in which those people are molested by falsities, at which time they undergo temptations, and the way in which after that they are set free in order that they may be led into heaven.

[2] But the contents of the internal sense of this verse and of those that follow hold an even deeper mystery which the Church does not yet know about and which must therefore be disclosed. Those who are termed spiritual are people for whom only the understanding part of their mind, not the will part, can be regenerated. In the understanding part of their mind the Lord therefore implants a new will, a will which conforms to the teachings that compose the faith of their Church. These people, that is to say, spiritual ones such as these, were saved solely by the Lord's Coming into the world. The reason why is that the Divine passing through heaven, which was the Divine Human before the Lord's Coming, could not reach them; for to be sure the teachings of their Church were for the most part not truths, and consequently the good in their will was not good either, 6427. Since those people could be saved solely by the Lord's Coming, they could not be raised into heaven before then. They were therefore kept in the meantime on the lower earth, in places there which in the Word are called 'pits'. This lower earth was besieged on every side by the hells where there were falsities, by which they were molested greatly during that time. In spite of this however the Lord protected them. But after the Lord came into the world and made the Human within Himself Divine, He set free those who were in the pits there and raised them to heaven. From these He also formed the spiritual heaven which is the second heaven. This is what is meant by the Lord's descent into the lower parts ¹ and by His deliverance of those who had been bound.

[3] This is the even deeper mystery that is described in the internal sense of this verse and of those that follow. See what has been shown already regarding those who are spiritual,

The spiritual are in obscurity so far as the truth and good of faith are concerned, 2708, 2715, 2718, 2831, 2849, 2935, 2937, 3241, 3833, 6289.

Their obscurity is lightened by the Lord's Divine Human, 2716, 4402.

Because they are in obscurity so far as the truth and good of faith are concerned they are under strong attack from the hells; but the Lord is constantly protecting them, 6419.

Those who are spiritual cannot have the will part of their mind regenerated, only the understanding part; and there the Lord forms a new will, 863, 875, 895, 927, 918, 1023, 1043, 1044, 2156, 4328, 4493, 5113.

The spiritual were saved by the Lord's Coming into the world, 2833, 2834, 3969.

[4] Various places in the prophetical part of the Word mention 'the bound' or 'the bound in the pit' and the fact that the Lord delivered them. The bound' should be taken to mean specifically those spoken of just above, as in Isaiah,

I Jehovah have called you in righteousness, and will hold your hand, because I will guard you, and give you to be a covenant of the people, ² a light of the nations, to open the blind eyes, to bring the bound out of prison, out of the dungeon-house those who sit in darkness. Isaiah 42:6-7.

In the same prophet,

I have guarded you, and I have given you as covenant of the people - to restore the land; to share out the devastated inheritances; to say to the bound, Go out; to those who are in darkness, Reveal yourselves. They will feed along the ways, and on all slopes will their pasture be. Isaiah 49:8-9.

This plainly refers to the Lord. 'The bound' stands in particular for those who were held back on the lower earth until the Lord's Coming, when they were raised up to heaven, and in general for all who are governed by good, yet are held back as though bound by falsities, from which however they wish to break away.

[5] In Zechariah,

Through the blood of your covenant I will let out your bound ones from the pit. Zechariah 9:11.

In Isaiah,

They will surely be gathered together, the bound ones in the pit, and they will be shut up in the dungeon; after a multitude of days they will be visited. Isaiah 24:21.

'The bound ones in the pit' stands for the same people. And in addition to these places the same meaning can be seen from the following words in Isaiah,

Jehovah has anointed Me to bring good tidings to the poor. He has sent Me to bind up the broken in heart; to preach liberty to captives, to those who are bound, to him who is blind; to proclaim the year of Jehovah's good pleasure. Isaiah 61:1-2.

And elsewhere,

The people walking in darkness have seen a great light; those dwelling in the land of the shadow of death, upon them has the light shone out. Isaiah 9:2.
