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.

2495. It has been stated and shown in many places already that the Word has an internal sense within it that is not seen in the letter. Also the nature of that sense is evident from the explanation given so far from Genesis 1 onwards. Even so, because the few at the present day who do believe in the Word do not in spite of that belief know about the existence of such an internal sense, let further confirmation of it be given.

[2] The Lord describes the close of the age, that is, the final period of the Church, as follows,

Immediately after the affliction of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken. Matthew 24:29; Mark 13:24-25.

That 'the sun' here does not mean the sun, nor 'the moon' the moon, nor 'the stars' the stars, but that 'the sun' means love to the Lord and charity towards the neighbour, 'the moon' faith received from love and charity, and 'the stars' cognitions of good and truth, has been shown in 31, 32, 1053, 1521, 1529-1531, 2120, 2441. Thus these words spoken by the Lord mean that when the close of the age or final period has arrived there will no longer be any love or any charity, or consequently any faith. It is evident that this is their meaning from similar words of the Lord that occur in the Prophets, as in Isaiah,

Behold, the day of Jehovah comes, to make the earth a desolation, and He will destroy its sinners from it. For the stars of the heavens and their constellations will not shine with their light. The sun will be darkened in its rising, and the moon will not give its light. Isaiah 13:9-10.

This too refers to the final period of the Church, or what amounts to the same, the close of the age.

[3] In Joel,

A day of darkness and thick darkness, a day of cloud and obscurity. The earth quaked before Him, the heavens trembled. The sun and the moon were darkened, and the stars withdrew their shining. Joel 2:2, 10.

Here the meaning is similar. Elsewhere in the same prophet,

The sun will be turned into darkness, and the moon into blood, before the great and terrible day of Jehovah comes. Joel 2:31.

In addition in the same prophet,

The day of Jehovah is near. The sun and the moon have been darkened, and the stars have withdrawn their shining. Joel 3:14-15.

In Ezekiel,

When I have blotted you out, I will cover the heavens and darken their stars, I will cover the sun with a cloud, and the moon will not give its light. All the bright lights in the heavens I will make dark over you, and I will put darkness over your land. Ezekiel 32:7-8.

Likewise in John,

When he opened the sixth seal I looked, and behold, a great earthquake took place, and the sun became black as sackcloth made of hair, and the full moon became like blood, and the stars fell to the earth. Revelation 6:12-13.

In the same book,

The fourth angel sounded, so that the third part of the sun was struck, and the third part of the moon, and the third part of the stars, and a third part of them was darkened. Revelation 8:12.

[4] These places show clearly that the Lord's words in the Gospels embody much the same as the Lord's words in the Prophets - namely that in the last times there will be no charity and no faith - and that this is the internal sense. All this is further evident in Isaiah,

The moon will blush, and the sun be ashamed, for Jehovah Zebaoth will reign on Mount Zion and in Jerusalem. Isaiah 24:23.

The meaning here is that faith, which is 'the moon', will blush, and charity, which is 'the sun', will be ashamed because their condition is such; for it cannot be said of the moon and the sun that they will blush and be ashamed. And in Daniel,

The horn of the he-goat grew towards the south, and towards the east, and grew even towards the host of heaven, and it cast down to the earth some of the host, and of the stars, and trampled on them. Daniel 8:9-10.

Here it is evident to anyone that 'the host of heaven' does not mean a host, nor 'the stars' the stars.
