2979. Abraham buried Sarah his wife. That this signifies that they received from the Lord truth conjoined with good, is evident from the signification of "burying," as being to regenerate (see n. 2916, 2917; that man is regenerate when he has received from the Lord truth conjoined with good will be shown presently); from the representation of "Abraham," as being the Lord (of which often before); and from the representation of "Sarah as a wife," as being truth conjoined with good (see n. 2063, 2065, 2507).
 With the regeneration of the spiritual man the case is this. He is first instructed in the truths of faith, and then he is held by the Lord in the affection of truth. The good of faith, which is charity toward the neighbor, is at the same time insinuated into him, but in such a way that he is scarcely aware of it; for it lies hidden in the affection of truth, and this to the end that the truth which is of faith may be conjoined with the good which is of charity. As time goes on, the affection of truth which is of faith increases, and truth is regarded for the sake of its end, that is, for the sake of good, or what is the same, for the sake of the life, and this more and more. Thus is truth insinuated into good, and when this takes place the man imbues himself with the good of life according to the truth that has been insinuated; and so he acts or seems to himself to act from good. Previous to this time, the truth of faith was principal, but afterwards the good of life becomes so.
 When this is the case the man is regenerate; but he is regenerate according to the quality and the amount of the truth that has been insinuated in good; and when truth and good act as one, he is regenerate according to the quality and the amount of the good: such is the case with all regeneration. Regeneration is effected to the end that man may be received into heaven. Heaven is nothing else than the marriage of truth and good, and of good and truth (see n. 2508, 2618, 2728, 2729); and if the marriage of truth and good be not formed with a man, he cannot be in the heavenly marriage, that is, in heaven.
