8644. 'The father-in-law of Moses' means the source of the good that was joined to God's truth. This is clear from the meaning of 'the father-in-law' as the good from which sprang the good that was joined to truth, dealt with in 6827; and from the representation of 'Moses' as God's truth, dealt with in 6752, 6771, 7010, 7014, 7382. The reason why 'the father-in-law' means the good from which sprang the good that was joined to truth is that the wife means good when the man means truth, 2517, 4510, 4823. Since the subject in what follows below is the joining together of Divine Good and Divine Truth, to the end that the arranging of truths into order may as a result take place with the member of the Church, it should be recognized that there is a difference between Divine Good and Divine Truth, in that Divine Good exists within the Lord, but that Divine Truth emanates from the Lord. They are like the fire of the sun and the light radiating from it. Fire exists within the sun but the light radiates from the sun; light holds no fire, only heat.

[2] Furthermore in the next life the Lord is the Sun, and He is the Light too. The Sun there, that is, He Himself, is Divine fire, which is the Divine Good of Divine Love. That Sun is the source of Divine light, which is Divine Truth emanating from Divine Good. This Divine Truth also holds within it Divine Good, though not such as it is in the Sun; it is modified for its reception in heaven. Unless it had been modified for reception, heaven could not have come into existence; for no angel can bear the flame coming from Divine Love. An angel would be consumed by it instantly, just as anyone would be the instant that the flame of the sun in the world breathed on him.

[3] But the way in which the Divine Good of the Lord's Divine Love is modified for reception cannot be known by anyone, not even by angels in heaven, because it is a modification of the Infinite for the finite. The Infinite is such that it lies far beyond all the power of understanding which the finite possesses, so far beyond that when that power of understanding tries to fix its attention on the Infinite it falls away like someone sinking into the depths of the sea and perishes. Regarding the Lord, that He is the Sun in heaven, that the Sun there is the Divine Good of His Divine Love, and that the Light from it is Divine Truth, the source of intelligence, see 1053, 1521-1533, 1619-1632, 2776, 3094, 3138, 3190, 3195, 3222, 3223, 3225, 3339, 3341, 3636, 3643, 3993, 4180, 4302, 4408, 4409, 4415, 4523, 4533, 4696, 7083, 7171, 7174, 7270, 8197.

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.
