3373. And unto thy seed. That this signifies truth, is evident from the signification of “seed,” as being truth (see n. 29, 255, 1025, 1447, 1610, 1940, 2848, 3310); thus it signifies the truth which is from the Lord’s Divine, which is “thy seed.” They who apprehend the Word only according to the sense of the letter cannot know but that “seed” denotes posterity, consequently here the posterity of Isaac from Esau and Jacob, and chiefly from Jacob, because the Word was in that nation and it contains so many historical facts concerning them. But in the internal sense by “seed” there is not meant any posterity from Isaac, but all those who are sons of the Lord, thus the sons of His kingdom, or what is the same, who are in good and truth from the Lord; and because these are “seed,” it follows that the very good and truth from the Lord are “seed,” for hence come the sons; wherefore also the very truths from the Lord are called the “sons of the kingdom,” in Matthew:

He that soweth the good seed is the Son of man; the field is the world; the good seed are the sons of the kingdom (Matthew 13:37-38);

hence also by “sons” in general are signified truths (n. 489, 491, 533, 1147, 2623).

[2] Everyone who thinks somewhat more deeply or interiorly may know that in the Divine Word by the “seed of Abraham, of Isaac, and of Jacob,” so often mentioned, and concerning which it is so frequently said that it should be blessed, and this above all nations and people in the world, cannot be signified their posterity; for above all nations they were least of all in the good of love to the Lord and of charity toward the neighbor, and were not even in any truth of faith; for they were utterly ignorant of what the Lord is, what His kingdom, thus what heaven is, and what the life after death, both because they did not want to know, and because if they had learned about these things, they would at heart have totally denied them, and would thus have profaned interior goods and truths, just as they so frequently profaned exterior ones by becoming open idolaters; which is the reason why in the sense of the letter of the Word of the Old Testament any interior things so rarely stand forth to view. Being of this nature, the Lord has said concerning them, quoting Isaiah:

He hath blinded their eyes, and hardened their heart, lest they should see with their eyes and understand with their heart, and should be converted, and I should heal them (John 12:40);

and again when they said:

We are Abraham’s seed; Abraham is our father; Jesus said unto them, If ye were Abraham’s sons, ye would do the works of Abraham; ye are of your father the devil, and the desires of your father ye will to do (John 8:33, 39, 44);

by “Abraham” here is meant the Lord, as everywhere in the Word; and that the Jews were not his seed, or sons, but the seed of the devil, is plainly stated. All this shows very plainly that by the “seed of Abraham, of Isaac, and of Jacob” as mentioned in the historical and prophetical Word, are by no means meant their posterity-for the Word throughout is Divine-but all those who are the Lord’s “seed,” that is, who are in the good and truth of faith in Him. (That from the Lord alone comes heavenly seed, that is, all good and truth, may be seen above n. 1438, 1614, 2016, 2803, 2882-2883, 2891, 2892, 2904, 3195)

2803. That the Divine Truth is the “son,” and the Divine Good the “father,” is evident from the signification of a “son,” as being truth (see n. 489, 491, 533, 1147, 2633); and of a “father,” as being good; and also from the conception and birth of truth, which is from good. Truth cannot be and come forth [existere] from any other source than good, as has been shown many times. That the “son” here is the Divine Truth, and the “father” the Divine Good, is because the union of the Divine Essence with the Human, and of the Human Essence with the Divine, is the Divine marriage of Good with Truth, and of Truth with Good, from which comes the heavenly marriage; for in Jehovah or the Lord there is nothing but what is infinite; and because infinite, it cannot be apprehended by any idea, except that it is the being and the coming forth [esse et existere] of all good and truth, or is Good itself and Truth itself. Good itself is the “Father,” and Truth itself is the “Son.” But because as before said there is a Divine marriage of Good and Truth, and of Truth and Good, the Father is in the Son, and the Son is in the Father, as the Lord Himself teaches in John:

Jesus saith unto Philip, Believest thou not that I am in the Father and the Father in Me ? Believe Me that I am in the Father and the Father in me (John 14:10-11).

And again in the same Evangelist:

Jesus said to the Jews, Though ye believe not Me, believe the works; that ye may know and believe that the Father is in Me, and I in the Father (John 10:36, 38).

And again:

I pray for them; for all Mine are Thine, and Thine are Mine; and that they all may be one, as Thou Father art in Me, and I in Thee (John 17:9-10, 21).

And again:

Now is the Son of man glorified, and God is glorified in Him; if God be glorified in Him, God shall also glorify Him in Himself. Father, glorify Thy Son, that Thy Son also may glorify Thee (John 13:31-32; 17:1).

[2] From this may be seen the nature of the union of the Divine and the Human in the Lord; namely, that it is mutual and alternate, or reciprocal; which union is that which is called the Divine Marriage, from which descends the heavenly marriage, which is the Lord’s kingdom itself in the heavens—thus spoken of in John:

In that day ye shall know that I am in My Father, and ye in Me, and I in you (John 14:20).

And again:

I pray for them, that they all may be one, as Thou Father art in Me and I in Thee, that they also may be one in us, I in them and Thou in Me; that the love wherewith Thou hast loved Me may be in them, and I in them (John 17:21-23, 26).

That this heavenly marriage is that of good and truth, and of truth and good, may be seen above (n. 2508, 2618, 2728, 2729 and following numbers).

[3] And because the Divine Good cannot be and come forth without the Divine Truth, nor the Divine Truth without the Divine Good, but the one in the other mutually and reciprocally, it is therefore manifest that the Divine Marriage was from eternity; that is, the Son in the Father, and the Father in the Son, as the Lord Himself teaches in John:

And now O Father, glorify Thou Me with Thyself, with the glory which I had with Thee before the world was (John 17:5, 24).

But the Divine Human which was born from eternity was also born in time; and what was born in time, and glorified, is the same. Hence it is that the Lord so often said that He was going to the Father who sent Him; that is, that He was returning to the Father. And in John:

In the beginning was the Word (the “Word” is the Divine Truth itself), and the Word was with God, and the Word was God; the same was in the beginning with God. All things were made by Him, and without Him was not anything made that was made. And the Word was made flesh, and dwelt among us, and we saw His glory, the glory as of the Only-begotten of the Father, full of grace and truth (John 1:1-3, 14; see also John 3:13; 6:62).
