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.

2661. 'Because of his son' means for the reason that He delighted in it, that is, in the first rational. This is clear from the meaning of 'son', that is to say, the son of the servant-girl, as the merely human or first rational, dealt with already. The reason for the grief is not actually mentioned here but it is nevertheless evident from what follows. Love is plainly the reason for that grief, for it is said [that Abraham was distressed] 'because of his son', and this son is the subject in verses 13-21 which follow. But so that it may be known why this grief existed, that is, why it is said that 'the matter was deeply distressing to Abraham because of his son', let the following few comments serve by way of illustration.

[2] The Lord did not come into the world to save those who are celestial, but to save those who are spiritual. The Most Ancient Church, which was called Man, was celestial, and if this Church had remained uncorrupted there would have been no need for the Lord to be born a human being. But as soon as it began to decline the Lord foresaw that the celestial Church would cease to exist altogether in the world, and therefore a prophecy was given there and then about the Lord's Coming into the world, Genesis 3:15. After the era of that Church there was no longer a celestial Church but a spiritual Church. The Ancient Church, which came after the Flood, was this spiritual Church, referred to many times in Volume One. This Church, or the people who belonged to the spiritual Church, could not have been saved unless the Lord had come into the world. This is what the Lord's words in Matthew are used to mean,

Those who are well have no need of a physician, but those who are sick. I did not come to call the righteous, but sinners to repentance. Matthew 9:12-13.

And the following in John are used with the same meaning,

And other sheep I have which are not of this fold; I must bring them also, and they will hear My voice, and there will be one flock and one shepherd. John 10:16.

And the same is also meant in the parable about the hundred sheep, in Matthew 18:11-13.

[3] Now seeing that 'Isaac', representing the Lord's Divine Rational, also means those that are celestial, who are called 'heirs', while 'Ishmael', representing the Lord's merely human rational, also means those that are spiritual, who are referred to as 'sons' - as may also be evident from what has been stated above in 2658 - the words used in the present verse therefore mean that because of His Divine Love the Lord suffered grief. This is also the meaning of what follows in verses 13-21, where Hagar's son and she his mother represent the spiritual Church, and where the subject is the state of that Church, that is, of those who are members of that Church, 2612. Any further declaration regarding these arcana is not as yet possible. All that can be stated here is that with the Lord when in the world all states of the Church were represented, and also the way in which those who belonged to it were to be saved through Him. Consequently the same states of the Church are also meant by those same names.
