Arcana Coelestia #3380
3380. And in thy seed shall all the nations of the earth be blessed. That this signifies all who are in good, both within and without the church, is evident from the signification of “being blessed,” as being to be made fruitful in good and to be multiplied in truths (see n. 981, 1422, 1731, 2846, 3140); from the signification of “seed,” as being the goods and truths which are from the the Lord, (n. 3373); and from the signification of the “nations of the earth,” as being all who are in good (n. 1259, 1260, 1416, 1849). Thus by “all the nations of the earth being blessed in thy seed,” is signified that through the good and truth which are from the Lord all are saved who live in mutual charity, whether they are within the church or without it. (That the Gentiles who are without the church and who are in good are equally saved, may be seen above, n. 593, 932, 1032, 1059, 1327-1328, 2049, 2051, 2284, 2589-2604, 2861, 2986, 3263)
Arcana Coelestia #1731
1731. He blessed him. That this signifies the enjoyment of celestial and spiritual things, may be seen from the signification of “blessing,” as being to enjoy all goods (see n. 981, 1096). They are in the enjoyment of all goods who enjoy celestial and spiritual goods; for all goods, of whatever name, are from these. The things which are contained in this versedeclare and proclaim the conjunction of the Lord’s Human Essence with His Divine Essence; the blessing itself involves this.
