2524. 'She herself also said, He is my brother' means that the rational itself so declared that celestial good should be coupled with it. This becomes clear from the meaning of 'a sister', to whom 'she herself' refers here, as the rational, 1495, 2508, and from the meaning of 'a brother' as good that stands related to truth, 367, 2508. For the implications of this are as follows: Divine Good and Divine Truth are united to each other as if in a marriage. From this comes the heavenly marriage, and also conjugial love, even down to the natural world below. But the good and truth of the rational are not joined to each other as if in a marriage but as in a blood relationship like that of brother and sister. For as regards truth, the rational is conceived from an influx of Divine Good into the affection for knowledge and cognitions, see 1895, 1902, 1910, whereas the good of the rational comes through an influx of Divine Good into that truth, which then becomes that good itself which belongs to charity and is 'the brother' of faith, or what amounts to the same, of truth, 367.

[2] As regards the way in which the good and truth of the rational are acquired, its good comes from Divine good, but not its truth from Divine truth, for the truth of the rational is acquired through knowledge and cognitions which are implanted by means of the senses, external and internal, and so by an external route. Consequently many illusions that result from sensory impressions cling to the truths of that rational which cause those truths not to be truths. Nevertheless when Divine Good flows into them and takes hold of them they are in that case seen as truths and are acknowledged as truths, even though they are no more than appearances of truth. The good itself within those truths undergoes modification determined by the shadows there and comes to have the same nature as the truth. This is one arcanum which lies concealed in these words, that the rational so declared that celestial good should be coupled with it.

1902. 'And Abram hearkened to Sarai's voice' means it could not have been achieved in any other way. This becomes clear from the train of thought in the internal sense and from the necessity that the human rational can be born in this and no other way. If man were not steeped in any hereditary evil, the rational would be born straightaway from the marriage of the celestial things belonging to the internal man with the spiritual things belonging to the same; and through the rational the faculty of knowing would be born. This would mean that on entering the world a person would possess straightaway within himself fully-formed faculties of reason and of knowing, for this would all be in accordance with the order that belongs to influx. This may be deduced from the fact that all animals without exception are born into a fully-formed faculty of knowing what they need and what is suitable for them in the way of food, safety, habitat, and producing offspring, because their inborn nature is in accordance with order. For what other reason is man born without the same faculties than that in his case order has been destroyed - for he alone is born without any knowledge?

[2] That which causes him to be born without any knowledge is hereditary evil received from his father and from his mother. Because of that evil all his faculties are turned in a contrary direction insofar as goods and truths are concerned, so that the latter are not able through an immediate influx of celestial and spiritual things from the Lord to be translated into correspondent forms. This is the reason why man's rational has to be formed in an entirely different manner or way, that is to say, by means of facts and cognitions entering in through the senses, and so by the external route, thus by what is a reversal of order. In this way, miraculously so, a person is made rational by the Lord. This is described by 'going in to the servant-girl', which means the joining of the internal man to the exterior man, and by the statement that 'Abram hearkened to the voice of Sarai', which means that it could not have been achieved in any other way.

[3] Because the Lord was born as any other is born and had a heredity from the mother, He was like any other in this respect also, the purpose being that through the conflicts brought about by temptations and through victories He might restore all things to order. His Rational as well therefore was conceived and born as it is with any other, yet with the difference that the Divine, or Jehovah - and so the life belonging to love towards the whole human race, on whose behalf and for whose salvation He fought in all His temptations - resided in every single thing that was His inmostly.
