3494. 'And he called Esau his elder son' means the affection for natural good, or the good of life. This is clear from the representation of 'Esau' as the Divine Good of the Natural, dealt with in 3300, 3302, 3322. And because the good of the natural is that which manifests itself in affection and life, it is accordingly the affection for natural good, or the good of life, that 'Esau' represents here. The affection for good in the natural and consequently the good of life is that which is called 'the elder son', whereas the affection for truth and consequently the doctrine of truth is that which is called 'the younger son'. The fact that the affection for good and consequently the good of life is the elder son, that is, the firstborn, is quite evident from the consideration that good reigns in anyone's children at first. Indeed they are in a state of innocence, and a state of love towards their parents or nursemaid, and a state of mutual charity towards playmates, so that good is the firstborn with everyone. This good which is fostered in this state within a person when he is a small child remains with him, for whatever is instilled in infancy acquires life to itself; and because it remains it becomes the good of life. Indeed if a person were devoid of such good as he has had with him from earliest childhood he would not be human but would be more savage than any wild animal of the forest. Not that its presence is apparent, for everything that has been instilled in earliest childhood inevitably appears to be something natural, as is quite evident from being able to walk, from all our other bodily movements, and from the right and proper ways to behave among other people; also from being able to talk, and from so many other abilities. From this it may be seen that good is 'the elder son', that is, the firstborn, and truth therefore 'the younger son', or one born later, for truth is not learned until childhood, adolescent, and adult years are reached.

[2] Each of them, good and truth in the natural or external man, is 'a son', that is to say, a son of the rational or internal man, for whatever comes into being in the natural or external man flows in from the rational or internal man, and from there comes into being and is born. That which does not come into being and is not born from there is not living and human, but is like what you might call body and senses without a soul. Hence both good and truth are called 'sons', and indeed sons of the rational. Yet it is not the rational that produces and gives birth to the natural, but an influx by way of the rational into the natural, an influx coming from the Lord. His 'sons' therefore are all the young children who are born, and after that time whenever they become wise. Also, insofar as the latter are at that time 'young children' - that is, insofar as the innocence of a young child, the love of a child for its parent (who is now the Lord), and mutual charity towards playmates (who are now the neighbour) exist in them, they are adopted by the Lord as 'sons'.

3138. These three verses deal with the preparation and enlightenment of the natural man so that the truth which was to be joined to good in the Rational might be summoned from there. With regard to that preparation and enlightenment the position is that there are two kinds of light which shape man's intellectual concepts - the light of heaven, and the light of the world. The light of heaven comes from the Lord who to angels in the next life is the Sun and Moon, see 1053, 1521, 1529, 1530. The light of the world comes from the sun and moon which a person sees with his physical eyes. The internal man receives his sight and understanding from the light of heaven whereas the external man receives his sight and understanding from the light of the world. The influx of the light of heaven into ideas formed in the light of the world produces enlightenment and at the same time recognition - the recognition of truth if a correspondence exists, the recognition of falsity instead of truth if that correspondence does not exist. But enlightenment and recognition are not possible unless affection or love is present, which is spiritual warmth and imparts life to the things illumined by the light. This may be compared to the light of the sun. It is not the light of the sun but the warmth within the light that imparts life to plants, as is evident from the seasons of the year.

[2] The verses which follow immediately after this describe the preparation further - the light of heaven, which is the Lord's Divine light, flowed into the ideas formed in the light of the world in His natural man so that He might bring forth from there the truth that was to be joined to good in the Rational. Thus it was to be brought forth in what is the ordinary way. Therefore to make His Human Divine the Lord came into the world in the ordinary way, that is, He was willing to be born as any other person is born, to receive instruction as any other does, and to be born again as any other, but with this difference: Man is born again from the Lord, whereas the Lord not only regenerated Himself from Himself, but also glorified Himself, that is, made Himself Divine; also man is made new through the influx of charity and faith, whereas the Lord was made so through the influx of Divine Love that was within Him and that was His own. From this it may be seen that man's regeneration is an image of the Lord's glorification, or what amounts to the same, that in the process of man's regeneration as the image one can envisage, though remotely, the process of the Lord's glorification.
