3373. 'And to your seed' means truth. This is clear from the meaning of 'seed' as truth, dealt with in 29, 255, 1025, 1447, 1610, 1940, 2848, 3310, and so truth from the Lord's Divine, which is 'your seed'. Those who understand the Word solely according to the sense of the letter can know no more than this, that 'seed' means descendants - here Isaac's descendants through Esau and Jacob, primarily through Jacob since the Word existed among that nation and so many of its historical descriptions have to do with them. But in the internal sense 'seed' is not used to mean any descendants from Isaac but all who are the Lord's 'sons', and so who are 'the sons of His kingdom', or what amounts to the same, those in whom good and truth which come from the Lord are present. And as these constitute 'the seed' it follows that good and truth themselves from the Lord are 'the seed', for these are what make people His 'sons'. This is also the reason why truths themselves which come from the Lord are called 'the sons of the kingdom' in Matthew,

He who sows the good seed is the Son of Man, the field is the world, the seed are the sons of the kingdom. Matthew 13:37-38.

And for this reason also 'sons' generally means truths, 489, 491, 533, 1147, 2623.

[2] Anyone who thinks rather more deeply or inwardly may recognize that the seed of Abraham, Isaac, and Jacob, mentioned so many times, and spoken of so many times as those who were to be blessed, and more so than all nations and peoples in all the world, cannot in the Divine Word mean the descendants of those three. For among all nations they least of all were moved by the good that flows from love to the Lord and from charity towards the neighbour. Nor indeed did any truth of faith exist with them. Who the Lord is, what His kingdom is, and so what heaven is and what the life after death, they did not know at all. They did not know these things because for one thing they did not wish to know and for another because if they had come to know about them they would have denied them completely in their hearts and so would have profaned interior goods and truths, as they did exterior by becoming on so many occasions open idolaters. This is the reason why any interior truths are rarely visible in the literal sense of the Old Testament Word. Because the nature of those people was such, the Lord therefore said about them, quoting Isaiah,

He has blinded their eyes and hardened their heart, lest they see with their eyes and understand with their heart, and are converted and I heal them. John 12:40.

What He said about them when they declared they were 'the seed of Abraham',

They said, We are the seed of Abraham. Our father is Abraham. Jesus said to them, If you were Abraham's sons, you would do the works of Abraham. You are from your father the devil, and the desires of your father you will to do. John 8:33, 39, 44.

Here also 'Abraham' is used to mean the Lord, as in every other instance in the Word. The Lord explicitly states that they were not His seed or sons but came from the devil. From this it is quite evident that 'the seed of Abraham, Isaac, and Jacob' in both the historical part and the prophetical part of the Word is in no way used to mean such descendants, for the Word is Divine in every detail Instead it means all who constitute 'the Lord's seed', that is, those with whom the good and truth of faith in Him are present. The fact that heavenly seed, that is, all good and truth, comes from the Lord alone, see 1438, 1614, 2016, 2803, 2882, 2883, 2891, 2892, 2904, 3195.

2803. As regards Divine Truth being meant by 'son' and Divine Good by 'father', this becomes clear from the meaning of 'son' as truth, dealt with in 489, 491, 533, 1147, 2623, and of 'father' as good, and also from the conception and birth of truth as taking place from good. As has been shown many times, truth cannot have being or manifest itself except from good. The reason 'son' here means Divine Truth, and 'father' Divine Good, is that the union of the Divine Essence with the Human Essence, and of the Human Essence with the Divine Essence, is the Divine Marriage of Divine Good to Truth, and of Truth to Good; and from that marriage comes the heavenly marriage. For within Jehovah or the Lord there is nothing but that which is infinite, and this being so, no other idea can be conceived of Him than that He is the Being and Manifestation (Esse et Existere) of all good and truth, that is, He is Good itself and Truth itself. Good itself is the Father, and Truth itself the Son. Now because the Divine Marriage, as has been stated, is a 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 said to Philip, Do you not believe 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 elsewhere in the same evangelist,

Jesus said to the Jews, Even though you do not believe Me, believe the works, that you may know and believe that the Father is in Me, and I in the Father. John 10:36, 38.

And elsewhere,

I pray for them - for all things that are Mine are Yours, and Yours are Mine - that they may all be one, as You, Father, are in Me and I in You John 17:9-10, 21.

And elsewhere,

Now is the Son of Man glorified, and God glorified in Him. If God is glorified in Him, God will also glorify Him in Himself. Father, glorify Your Son, that Your Son also may glorify You. John 13:31-32; 17:1.

[2] From these places one may see the nature of the union of the Divine and of the Human within the Lord - that each is linked mutually to the other and responds to the other - that is, it is a reciprocal union. This is the Union which is called the Divine Marriage, from which the heavenly marriage comes down, which is the Lord's kingdom itself in heaven and is referred to in John as follows,

On that day you will know that I am in My Father, and you in Me, and I in you. John 14:20.

And elsewhere,

I pray for these, that they may all be one, as You, Father, are in Me and I in You, that they also may be one in Us, I in them and You in Me, that the love with which You have loved Me may be in them, and I in them. John 17:21-23, 26.

[3] As regards this heavenly marriage being a marriage of good and truth, and of truth and good, see 2508, 2618, 2728, 2729 and following paragraphs. And since Divine Good cannot possibly have being or manifest itself without Divine Truth, and Divine Truth cannot possibly do so without Divine Good, but one is always reaching out to and responding to the other, it is therefore plain that the Divine Marriage has existed from eternity, that is, the Father in the Son, and the Son in the Father, as the Lord Himself teaches in John,

Now, Father, glorify Me in Your Own Self with the glory I had with You before the world was. John 17:5, 24.

But the Divine Human that had been born from eternity was also born in time, and what was born in time is the same as that which was glorified. This is what accounts for the Lord's saying many times that He was going to the Father who sent Him, that is, He was returning to the Father. And in John,

In the beginning was the Word (the Word being Divine Truth itself), and the Word was with God, and the Word was God. He was in the beginning with God. All things were made by Him, and without Him was not anything made that was made. Furthermore the Word became flesh and dwelt among us, and we beheld his glory, glory as of the Only Begotten from the Father, full of grace and truth. John 1:1-3, 14.
