3377. Verses 4-5 And I will cause your seed to multiply as the stars of heaven, and I will give to your seed all these lands; and in your seed all the nations of the earth will be blessed, because Abraham hearkened to My voice and practiced My observances, My commandments, My statutes, and My laws.

'I will cause your seed to multiply as the stars of heaven' means truths and cognitions of faith 'And I will give to your seed all these lands' means derivative Churches. 'And in your seed all the nations of the earth will be blessed' means all with whom good is present, both inside and outside the Church. 'Because Abraham hearkened to My voice' means the union of the Lord's Divine Essence with the Human Essence by means of temptations. 'And practiced My observances, My commandments, My statutes, and My laws' means through revelations constantly coming from Himself.

3636. It is an entirely general and all-embracing law that the Lord is the Sun of heaven and that this is the source of all the light in the next life; that nothing at all from the light of the world is visible to angels and spirits, that is, to beings in the next life; and also that the light of the world which comes from the sun is to angels nothing else than thick darkness. From the Sun of heaven, or the Lord, comes not only light but also warmth; but these are spiritual light and spiritual warmth. The light that strikes their eyes is seen as light but it holds intelligence and wisdom within it since it is the outward manifestation of these. And the warmth is experienced by their senses as warmth but has love within it since it is the outward manifestation of that love. This being so, love is called spiritual warmth and is also the producer of the warmth which man's life possesses, while intelligence is called spiritual light and is also the producer of the light which his life possesses. From this all-inclusive correspondence all other correspondences are derived, for every single thing has regard to good which belongs to love and to truth which belongs to intelligence.
