2670. Because he is thy seed. That this signifies that they also have salvation from the Lord’s Divine Human, is evident from what was said above (n. 2666). That “seed” is faith, but the faith of charity, may be seen above (n. 255, 880, 1025, 1447, 1610, 1940).

2666.

In Isaac shall thy seed be called. That this signifies that from the Lord’s Divine Human is all salvation for those who are in good, is evident from the representation of Isaac, as being the Divine rational (as shown before), thus the Divine Human (for the human commences in the inmost of the rational, n. 2106); and from the signification of “seed,” which is predicated of Isaac, as being the celestial rational, or what is the same, those who are celestial (see n. 2085, 2661). Thus that “thy seed shall be called” signifies that they will be heirs, consequently that they will have salvation. The spiritual also are “seed,” but from the son of the handmaid, as is said in the following verse: “and also the son of the handmaid, I will make him a nation, because he is thy seed;” and therefore the spiritual also have salvation if they are in good, as will appear from the internal sense of these words. The Lord also teaches the same in many places, and plainly in John:

As many as received Him, to them gave He power to become the sons of God, to them that believe in His name who were born, not of bloods, nor of the will of the flesh, nor of the will of man, but of God (John 1:12-13).
