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.

3138. These three verses deal with the preparation and enlightenment of the natural man so that the truth which was to be joined to good in the Rational might be summoned from there. With regard to that preparation and enlightenment the position is that there are two kinds of light which shape man's intellectual concepts - the light of heaven, and the light of the world. The light of heaven comes from the Lord who to angels in the next life is the Sun and Moon, see 1053, 1521, 1529, 1530. The light of the world comes from the sun and moon which a person sees with his physical eyes. The internal man receives his sight and understanding from the light of heaven whereas the external man receives his sight and understanding from the light of the world. The influx of the light of heaven into ideas formed in the light of the world produces enlightenment and at the same time recognition - the recognition of truth if a correspondence exists, the recognition of falsity instead of truth if that correspondence does not exist. But enlightenment and recognition are not possible unless affection or love is present, which is spiritual warmth and imparts life to the things illumined by the light. This may be compared to the light of the sun. It is not the light of the sun but the warmth within the light that imparts life to plants, as is evident from the seasons of the year.

[2] The verses which follow immediately after this describe the preparation further - the light of heaven, which is the Lord's Divine light, flowed into the ideas formed in the light of the world in His natural man so that He might bring forth from there the truth that was to be joined to good in the Rational. Thus it was to be brought forth in what is the ordinary way. Therefore to make His Human Divine the Lord came into the world in the ordinary way, that is, He was willing to be born as any other person is born, to receive instruction as any other does, and to be born again as any other, but with this difference: Man is born again from the Lord, whereas the Lord not only regenerated Himself from Himself, but also glorified Himself, that is, made Himself Divine; also man is made new through the influx of charity and faith, whereas the Lord was made so through the influx of Divine Love that was within Him and that was His own. From this it may be seen that man's regeneration is an image of the Lord's glorification, or what amounts to the same, that in the process of man's regeneration as the image one can envisage, though remotely, the process of the Lord's glorification.
