2189. They said unto him, Where is Sarah thy wife? That this signifies rational truth, which did not then appear because it was in rational good, is evident from the representation here of Sarah, as being rational truth (spoken of above, n. 2173). How the case is with these things, as also with those which follow, where the state of the rational with the Lord is treated of, which is represented by Sarah, cannot be so well explained to the understanding unless it is known what in general is the state of the rational as to good and as to truth; and with the Lord, as to the Divine and as to the Human in which He then was.
 The primary thing of the rational with man is truth (as before said, n. 2072), consequently it is the affection of truth, to the end that man may be reformed, and so regenerated. This is effected by means of knowledges [cognitiones et scientifica] that are of truth, which are continually being implanted in good, that is, in charity, that so the man may receive the life of charity. It is on this account that the affection of truth in man is predominant in his rational. For it is the case with the life of charity (which is the heavenly life itself) that with those who are being reformed and regenerated it is continually being born and growing up and receiving increments, and this by means of truths; therefore the more of truth there is insinuated, the more is the life of charity perfected; wherefore according to the quality and quantity of truth, so is the charity with a man.
 From all this it may in some measure be evident how the case is with man's rational. In truth, however, there is no life, but in good. Truth is only a recipient of life, that is, of good. Truth is as the clothing or garment of good; therefore also truths are called in the Word "clothing," and also "garments." But when good constitutes the rational, truth disappears and becomes as if it were good. Good then shines through the truth, in the same way as takes place with the angels, for when they appear clothed, it is a brightness inducing the appearance of raiment, as was the case also when angels appeared before the prophets.
 This then is what is meant by rational truth not then appearing because it was in rational good, and which is signified by their saying to him, "Where is Sarah thy wife?" But as the Lord's rational good was then Divine, such as it can be with no angel, it cannot be described otherwise than by comparison, and thus by illustration from something similar, and which is not the same.
