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.

2718. 'A wife from the land of Egypt' means the affection for knowledge, which the member of the spiritual Church possesses. This is clear from the meaning of 'a wife' as affection or good, dealt with in 915, 2517, and from the meaning of 'Egypt' as knowledge, dealt with in 1164, 1165, 1186, 1462. In this verse the member of the spiritual Church is described so far as the nature of his good, that is, the essence of his life, is concerned - that the good residing with him is obscure, but that it is brightened with light from the Lord's Divine Human. From that brightening of it the affection for truth arises in the rational part of his mind, and the affection for knowledge in the natural part. The reason the affection for good such as resides within the celestial man cannot arise in the spiritual man, but instead the affection for truth, is that the good residing with him is implanted in the understanding part of his mind, and is obscure compared with the celestial man's good, as shown in 2715. From this good no other type of affection can be generated and derived within his rational than the affection for truth, and through this affection for truth the affection for knowledge within the natural. No other truth is meant in this case than that which the person believes to be the truth, even though it may not in itself be the truth. Nor is knowledge used to mean such knowledge as the learned possess but all factual knowledge with which a person can be taught from what he experiences or hears in everyday life, from doctrine, and from the Word. It is the affection for such truth and knowledge that exists within the member of the spiritual Church.

[2] So that it may be known what is meant by the affection for truth existing with someone and what by the affection for good, let a brief statement be made regarding them. Those with the affection for truth think about, question, and discuss whether a thing is true, whether it is so. And when they are convinced it is true, or is so, they think about, question, and discuss what it is. Thus they remain rooted on the doorstep and cannot be admitted into wisdom until they no longer have any doubts. Those however with whom the affection for good exists know and perceive that the thing is so from the good itself governing them. Thus they do not remain on the doorstep but are in a room inside, having been admitted into wisdom.

[3] Take as an example the consideration that it is a celestial gift to think and to act from an affection for good, or from good. Those with whom the affection for truth exists discuss whether this is so, whether such a gift can exist, and what it may be. And so long as they are turning over doubts about it they are unable to be admitted. But those with the affection for good do not discuss or turn doubts over but assert that the thing is true and are for that reason admitted. For those with whom the affection for good exists, that is, those who are celestial, start off where those with the affection for truth, that is, those who are spiritual, come to a halt, so that the furthest point reached by the latter is the starting point for the former. That being so, those who are celestial are given to know, recognize, and perceive that affections for good are countless - as numerous as the communities in heaven - and that they are all joined together by the Lord into a heavenly form so as to constitute one human being so to speak. They are also given to define by perception the genus and species to which each affection belongs.

[4] Or take this example: All delight, blessedness, and happiness belong wholly to love, but the nature of the love determines that of the delight, blessedness, and happiness. The spiritual man fixes his mind on the question whether this is true and whether delight, blessedness, and happiness may not spring from some other source, such as from mixing with others, talking to others, meditation, or learning, and also whether they reside in possessions, position, reputation, and the glory resulting from these. As long as he is asking such questions he does not confirm himself in the truth that none of these accomplishes anything, only the affection born of love which is present within them and making them what they are. The celestial man however does not remain rooted in such preliminary questionings but immediately asserts that the thing is true. Consequently he is interested in the end in view and the realization of this, that is, he is governed by the very affections born of love which are countless, and in each one of which there are things beyond description, involving variations of delight, blessedness, and happiness that have no end.

[5] Take as a further example the consideration that the neighbour is to be loved for the good that resides with him. Those with whom the affection for truth exists think, question, and discuss whether this is true, that is, whether it is so. They ask what the neighbour is, what good is; but they go no further than this, and therefore they shut the door to wisdom against themselves. Those however with the affection for good assert that the thing is so and do not consequently shut the door against themselves but enter in and so come to know, recognize, and perceive from good who is pre-eminently the neighbour, also in what degree he is the neighbour, and that everyone in differing ways is the neighbour. Thus they perceive things beyond description, over and above what is known to those with the affection solely for truth.

[6] Take as yet another example the truth that a person who loves the neighbour for the good within him loves the Lord. Those with the affection for truth question whether this is so. And if they are told that anyone who loves the neighbour for the good within him loves the good, and that - since all good comes from the Lord and the Lord is present in good - when anyone loves good he also loves the Lord from whom that good comes and in which He is present, they then question whether that too is so. They also ask what loving good is, as well as what good is, and whether the Lord is present more so in good than in truth. As long as they remain rooted in such questionings they cannot get even a distant view of wisdom. But those with the affection for good know from perception that the thing is so and immediately behold the whole field of wisdom leading right on to the Lord.

[7] From these examples it may become clear why in comparison with those who have the affection for good, that is, with those who are celestial, obscurity exists with those who have the affection for truth, that is, with those who are spiritual Nevertheless the latter are able to pass from obscurity into light, provided that they are willing to adopt the affirmative attitude that all good belongs to love to the Lord and charity towards the neighbour; also that love and charity constitute spiritual conjunction, and that these are the source of all blessedness and happiness, thus that heavenly life consists in the good belonging to love received from the Lord, but not in the truth of faith separated from it.
