8351. 'And the people grumbled against Moses' means grief caused by the bitterness of the temptation. This is clear from the meaning of 'grumbling' as complaint, the kind made in temptations, thus grief caused by the bitterness of the temptation. The temptations which those belonging to the Lord's spiritual Church underwent after they had been delivered from molestations, in addition to the temptations which members of that Church are destined to undergo, are described by the grumblings of the children of Israel in the wilderness. And since spiritual temptations are as a general rule protracted till a person is in despair, 1787, 2694, 5279, 5280, 7147, 7166, 8165, 'grumbling' means complaint because of grief felt in temptations, as in Exodus 16:2-3; 17:3; Numbers 14:27, 29, 36; 16:11. The words 'against Moses' are used because it was a grumbling against what was Divine; for 'Moses' represents Divine Truth, 6723, 6752, 6771, 6827, 7010, 7014, 7089, 7382.

[2] As regards the temptations which those belonging to the spiritual Church underwent, and the temptations which members of that Church are destined to undergo, it should be recognized that no faith, nor thus any charity, can ever be instilled into those who belong to the spiritual Church except by means of temptations. In temptations a person is involved in conflict against falsity and evil. These - falsity and evil - flow into the external man from the hells, while goodness and truth flow in from the Lord by way of the internal man; and so there arises from a conflict of the internal man with the external that which is called temptation. And in the measure that the external man is brought into a state of obedience to the internal, faith and charity are instilled; for the external or natural level of a person is a receptacle of truth and good from the internal. If the receptacle is not properly adjusted it does not receive anything flowing in from the more internal level but either repels, destroys, or stifles it, as a consequence of which there is no regeneration. So it is that temptation is necessary, in order that a person may undergo regeneration, which is effected through the instillation of faith and charity, and thereby through the formation of a new will and new understanding. This also explains why the term 'militant' is applied to the Lord's Church. See what has been stated and shown already about these matters in 3928, 4249, 4341, 4572, 5356, 6574, 6611, 6657, 7090 (end), 7122, 8159, 8168, 8179, 8273.

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.
