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.

2172. That “Abraham” is here the Lord in that state as to good, is evident from the representation of Abraham. When he is speaking with Jehovah, as here, Abraham represents the Lord in the Human (as also before, n. 1989, where he represented the Lord in the state and at the age there described, because then also he spoke with Jehovah). In other cases Abraham represents the Lord’s Divine good, and Sarah His Divine truth; hence Abraham now represents the Lord’s rational good.
