The Writings offer a tremendous amount of material on angels. The book "Heaven and Hell" offers detailed discussions as it describes heaven; "Conjugial Love" has much to say about marriage and romantic love in heaven; "Divine Love and Wisdom" offers insight into how angels in their nature reflect the nature of the Lord. So we'll offer some basics here and recommend those books to those who want more detail.

Basically, the Writings say that if people in this life open themselves to the Lord, follow the Lord's teachings and let the Lord change their selfish desires into generous loves, they will go to heaven as angels after they die. If they don't, and instead embrace their selfishness, they will go to hell as evil spirits. The Writings also say that this is the only source of angels and evil spirits - they were all once people. There is no separately created race of angels, no fallen angel Lucifer who is now the Devil; that belief is based solely on a few lines of misinterpreted scripture.

This makes sense if you look at it logically. If the Lord could create beings that would live in love and harmony with him with no possibility of evil, why would He have bothered with us? Why not just make more of them? The fact is, such beings would not have any choice in their actions, making them no better than animals. And ultimately, if they were purely good then they would really just be extensions of the Lord, so in loving them He would be loving Himself. The reverse is true of the idea of Satan or "the" Devil. The Lord creates us from love so that he can love us, bring us to heaven and make us happy. For Satan to exist, the Lord would have had to create him, and it would be contrary to His essence to create something that was not intended for heaven, for joy, and for union with the Lord.

So angels were once people, who got to be angels by embracing the idea of being good and followed the Lord's teachings as best they could. The Writings make it clear these people can come from anywhere, from any religious background. Some churches may have doctrine that is closer to the truth than others, but the point of any religion is for people to desire to be good and try to be good using the tools they have.

When those people die, they go first to a place called the "world of spirits." There everyone who has recently died can learn about the Lord and spiritual life and prepare for heaven. There also, people's inner affections start showing on the surface; those who are ultimately evil start losing the ability to cover it up, and the love starts shining through for those who are ultimately good. As this continues and as people learn more, they naturally start congregating with others who have similar loves. This way evil people eventually take themselves to hell, where they can be with others who share their evil. Good people, on the other hand, can be prepared for heaven.

Two important things have to happen for us to truly enter fully into heaven. First, the Lord will push aside our remaining evil desires, so they cannot hurt us or tempt us anymore; angels are in a marvelous state of peace, with no active evil to trouble them. Second, we will each be led by the Lord to the perfect married partner, the one whose soul matches ours, the one we can love blissfully to eternity. All angels are married, because the marriage of a man and a woman represents the marriage of love and wisdom in the Lord, and also the marriage of the desire for good and understanding of truth in each of us. Because of this, we can only fully receive and return the Lord's love as married partners, and heaven is suffused with the sphere of marriage and the love of marriage.

The angelic couples will find their way to communities of other angels whose loves match their own, people with whom they can share the deepest friendships imaginable. They will have houses which reflect the character of their loves, and will be given work to do that springs from their loves and fills them with joy. Beyond that, their lives are much as life might be in this world, though free of sickness and aging and boredom and conflict. They have bodies that are human in form - no wings! - but a beauty in face and form that reflects the good loves they have inside. They eat and drink and laugh and sleep and have parties and games; all filled with the delight of mutual love.

The Writings tell us the work angels do is varied far beyond what we can imagine, though they only describe a few aspects. Among other things, angels care for people in this life, passing on to them true ideas and desires for good from the Lord. They also teach those in the World of Spirits, greet those who have just died, raise those who died as children, keep order in hell and do many other things.

We would finally note that there are three degrees of angelic life, based on the loves people embraced in this life. The first, lowest heaven, called the "natural heaven," is filled by those who are in the love of service. Angels there love to do what's right because they know it is right. The second, middle heaven, called the spiritual heaven, is filled by those who are in the love of the neighbor. Angels there love to engage their minds with spiritual questions to gain an ever-deeper understanding of how to be loving to one another. The third, highest heaven, known as celestial, is filled with those who are in love of the Lord Himself. From that love they have such innocence that they look like children, and they instantly perceive what is true, in all its variety, from the light of that love.

133. Something now needs to be said about heaven's warmth. In its essence, heaven's warmth is love. It emanates from the Lord as the sun, which is divine love for the Lord and from the Lord, as has been explained in the preceding chapter. We can therefore see that heaven's warmth is just as spiritual as its light, because they come from the same source. ¹

There are two things that emanate from the Lord as the sun, divine truth and divine good. Divine truth comes out in heaven as light and divine good as warmth. However, divine truth and divine good are so united that they are not two, but one. For angels, though, they are separated. There are angels who accept divine good more readily than divine truth, and there are angels who accept divine truth more readily than divine good. The ones who are more open to divine good are in the Lord's heavenly kingdom; the ones who are more open to divine truth are in the Lord's spiritual kingdom. The most perfect angels are the ones who are equally open to both.

2500. 'Abraham travelled from there towards the land of the south' means the Lord's advances in goods and truths of faith. This is clear from the meaning of 'travelling' as advancing, dealt with in 1457, and from the meaning of 'the land of the south' as the good and truth of faith, dealt with in 1458. Previously in Chapter 12 it was said of Abraham when entering Egypt that 'he travelled, going on and travelling towards the south', verses 9-10, which meant in the internal sense that the Lord, when a boy, made advances into goods and truths as regards knowledge consisting of cognitions, 1456, 1459. Now in the present chapter it is said that he travelled towards the land of the south, which means further and more interior advances, made this time into goods and truths as regards the doctrine of faith. This is why the expression 'the land of the south' is used here, for 'land' in its proper sense means the Church, for whose sake doctrine exists, 566, 662, 1066, 2117, 2118.

[2] As regards the Lord's instruction in general, the nature of it is quite plain from the internal sense of this chapter. From that sense it is plain that He was taught through a whole succession of revelations and so through Divine perceptions and thoughts from Himself, that is, from His Divine. These perceptions and thoughts He implanted in Divine intelligence and wisdom, and continued to do so until the perfect union of His Human and His Divine had been effected. This way of becoming wise is not at all open to anyone else, for it sprang from the Divine itself, which was His inmost, being the Father's, from whom He had been conceived. Thus it sprang from the Divine Love itself which the Lord alone possessed and which constituted His desire to save the entire human race.

[3] It is an arcanum as yet known by scarcely anyone that love itself holds wisdom and intelligence within it, but that the nature of these is determined by that of the love. The reason wisdom and intelligence exist within love is that all influx takes place into the love, or what amounts to the same, into the good, and so into the life itself of man. This is the source of the wisdom and intelligence possessed by angels, which are beyond description. It is the source also of the wisdom and intelligence possessed by men who are governed by love to the Lord and charity towards the neighbour. Although during their lifetime the latter do not discern at all the presence with them of such wisdom and intelligence, they nevertheless enter into these after death for the reason that they exist within love itself and within charity itself, see 2494. As for the Lord's love however, this was infinitely higher than the love which exists in angels, for it was Divine Love itself, and therefore He had within Himself the acme of all wisdom and intelligence. Yet into the possession of this, because He was born a human being (homo) and advanced as a human being does according to Divine order, He entered by successive degrees so that He might in that way unite His Human to the Divine and make it Divine, doing so by His own power.
