Arcana Coelestia #2085
2085. To his seed after him. That this signifies those who should have faith in the Lord, is evident from the signification of “seed,” as being faith (explained before, n. 1025, 1447, 1610, 2034). Those are here signified by “seed” who have the faith of love, that is, who have love to the Lord; consequently the celestial, or those who are of the celestial church; for the seed from Isaac is treated of. But they who have the faith of charity, that is, who have charity toward the neighbor-consequently the spiritual, or those who are of the spiritual church-are signified by “Ishmael,” who is treated of in the verse that now follows. (What the distinction is between the celestial and the spiritual, may be seen above, n. 2069, 2078; and also what the distinction is between having love to the Lord and having charity toward the neighbor, n. 2023)
Arcana Coelestia #1447
1447. And said, To thy seed will I give this land. That this signifies that celestial things should be given to those who should have faith in Him, is evident from the signification of “seed,” and from the signification of “land.” That “seed” signifies faith in the Lord, was shown above n. 255, 256); and that “land” signifies celestial things, was also shown above, at verse 1 of this chapter (and also n. 620, 636, 662, 1066). In the sense of the letter, by “the seed of Abram” is meant his posterity from Jacob, and by “land” is meant the land of Canaan itself, which would be given them for a possession, so that they might represent the celestial and spiritual things of the Lord’s kingdom and church, and that the Representative Church might be instituted among them, and because the Lord was to be born there; but in the internal sense nothing else is signified by “seed” than faith in the Lord, and by “land” nothing else than celestial things, and in the present passage that celestial things should be given those who should have faith in Him. What is meant by having faith in the Lord has already been shown repeatedly.
