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.

1530. The truth of this could be proved to anyone from the Word, for example, when the Lord revealed Himself to Peter, James, and John, for His face at that time shone like the sun and His garments became white as the light, Matthew 17:2. The sole reason why He appeared to them in this way was that their interior sight had been opened. The same is also confirmed from the Prophets, as in Isaiah when reference is being made to the Lord's kingdom in heaven,

The light of the moon will be as the light of the sun, and the light of the sun will be sevenfold, as the light of seven days. Isaiah 30:26.

And in John, where reference is being made to the Lord's kingdom which is called the New Jerusalem,

The city has no need of the sun or of the moon to shed light in it; for the glory of God gives it light, and its lamp is the Lamb. Revelation 21:23.

And elsewhere in the same book,

There will be no night there, nor do they need a lamp or light of the sun, for the Lord God gives them light. Revelation 22:5.

And in addition when the Lord appeared to Moses, Aaron, Nadab, Abihu, and the seventy elders, it is said that they saw the God of Israel under whose feet there was so to speak a paved work of sapphire stone, like the substance of the sky for clearness, Exodus 24:10. Because the Lord's celestial and spiritual appears before the external sight of the angels as the Sun and the Moon, 'the sun' in the Word therefore means what is celestial, and 'the moon' what is spiritual.
