[2] The manner in which the Lord's first rational was conceived and born has been stated in the previous chapter where Ishmael, who represented that rational, was the subject. This chapter and the next deal with that Rational which was made Divine by the Lord, something He achieved through the marriage-like conjunction of Divine Good with Divine Truth. The only possible way the first rational can be conceived is by the influx of the Internal Man into the External Man's affection for knowledge. Nor can it be born from anything other than the affection for knowledge, an affection represented by 'Hagar, Sarai's servant-girl', as shown in the previous chapter, in 1896, 1902, 1910, and elsewhere in that chapter.

[3] But the second or Divine Rational is not conceived and born in the same way but by the conjunction of Truth in the Internal Man with Good in the same, and the resulting influx. In the Lord's case this was achieved by His own power derived from the Divine itself, that is, from Jehovah. As stated in various places already, His Internal Man was Jehovah. And Good itself, represented by 'Abraham', belonged to the Internal Man, as also did Truth itself, represented by 'Sarah'. Both were on that account Divine, and from them both the Lord's Divine Rational was conceived and born. Indeed it was conceived and born from the influx of good into truth, and so by means of truth, for the principal element in the rational is truth, as stated above in 2072. Hence the statement here 'whom Sarah will bear to you', which means Divine Truth joined to Good from which it will come into being, and at verse 17 above the statement 'Sarah a daughter of ninety years' means that Truth joined to Good will accomplish this.

[4] With all human beings, since each has been created in the likeness and image of God, something similar yet not comparable takes place, in that his first rational too is conceived and born through the influx of his internal man into the life of his external man's affection for knowledge, but his second rational results from the influx of good and truth from the Lord by way of his internal man. This second rational he receives from the Lord when he is being regenerated, for at that time he senses within his rational what the good and truth of faith are. The internal man with anyone is above his rational, and is the Lord's. This is dealt with in 1889,1940.
