2092. My covenant will I set up with Isaac. That this signifies union with the Divine rational, is evident from the signification of a “covenant,” as being union (explained before); and from the representation of “Isaac,” as being the Divine rational (spoken of above, n. 2083).

1902. And Abram harkened to the voice of Sarai. That this signifies that it could not be done in any other way, may be seen from the connection in the internal sense, and from the necessity that exists for the rational to be born in this way. If man were imbued with no hereditary evil, the rational would then be born immediately, from the marriage of the celestial things of the internal man with its spiritual things, and the faculty of knowing would be born through the rational, so that on coming into the world a man would at once have in himself all the faculty of reason and of knowing, for this would be in accordance with the order of influx, as may be inferred from the fact that all animals whatever are born into all the faculty of knowing that is necessary and helpful in securing food, safety, habitation, and procreation, because their nature is in accordance with order. Why then is man not born into it, except for the reason that order has been destroyed in him, for he alone is born into no knowledge?

[2] The cause of his being so born is evil inherited from his father and mother. By reason of this all his faculties are turned in a contrary direction in regard to truths and goods, and therefore cannot be reduced into correspondent forms by the immediate influx of what is celestial and spiritual from the Lord. This is the reason why man’s rational must be formed by an altogether different process, that is, in a different way, namely, by means of knowledges [scientifica et cognitiones] introduced through the senses, thus flowing in by an external way, and so in inverted order. Man is thus made rational by the Lord in a miraculous manner. This is meant by “going in unto the handmaid,” by which is signified the conjunction of the internal man with the exterior man; and also by “Abram’s hearkening to the voice of Sarai,” which signifies that it could not be done in any other way.

[3] The Lord, being born as are other men, and because He had a nature inherited from the mother, was like other men also in respect to the miraculous formation of the rational by means of knowledges, to the end that by combats of temptations and by victories He might reduce all things into order. Therefore was His rational conceived and born in the same way as with other men, but with the difference that inmostly in all things that were His, in both general and particular, there was the Divine, or Jehovah, and thus the life of love toward the whole human race, for whom and for whose salvation He fought in all His temptations.
