2507. Of Sarah his wife. That this signifies spiritual truth conjoined with the celestial, is evident from the signification of “Sarah” as a wife, as being intellectual truth conjoined with the Divine good, or what is the same, spiritual truth conjoined with the celestial (see n. 1468, 1901, 2063, 2065, 2172, 2173, 2198). What the spiritual is, and what the celestial, has often been stated before (see n. 1155, 1577, 1824, 2048, 2088). That is called Celestial, which is of good, that is, which is of love to the Lord and of charity toward the neighbor; and that Spiritual, which is of truth, that is, which is of faith derived from those loves.

1901. It may be that I shall be built up by her. That this signifies that in this way the rational could be born, may be seen from the signification of being “built up,” when predicated of generation, and thus without explication. By “Sarai,” as has been said, is signified intellectual truth which has been adjoined as a wife to good. Intellectual truth, which appertains to the inmost, is altogether barren, or like a childless mother, when as yet there is not any rational into which and through which it may inflow; for without the rational as a medium intellectual truth cannot inflow with any truth into the exterior man, as may be seen from the case of little children, who can know nothing whatever of truth until they have been imbued with knowledges; but, as before said, the better and more perfectly they are imbued with knowledges, so much the better and more perfectly can intellectual truth which appertains to the inmost, or to good, be communicated.

[2] This intellectual truth, represented by Sarai, is the spiritual itself which flows in through heaven, and this by an internal way, and with every man; and it continually meets the knowledges that are insinuated by means of the things of sense, and are implanted in the memory. Man is not aware of this intellectual truth because it is too pure to be perceived by a general idea. It is like a kind of light that illuminates the mind, and confers the faculty of knowing, thinking, and understanding. As the rational cannot come into existence except by means of the influx of the intellectual truth represented by Sarai, it stands related to this truth as a son. When the rational is being formed from truths that have been adjoined to good, and still more when it is being formed from the goods from which are truths, it is then a genuine son. Before this it is indeed acknowledged as a son, yet not as a genuine son, but as coming from a handmaid; and still it is adopted, which is the reason why it is here said that she might be built up by her.
