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.

7166. 'Why is this, that You have sent me?' means when yet the law going forth from God seems to promise something different. This is clear from the meaning of 'Why is this?' as, Why is this so when something different is said? from the representation of Moses, who uses these words in reference to himself, as the law from God, dealt with just above in 7164; and from the meaning of 'being sent' as going forth, dealt with in 4710, 6831. Consequently 'Why is this, [that] you have sent me?' means that the law going forth from God seems to promise something different. Because these words are spoken by one complaining about the molestation by falsities, the law from God appears to promise something different. This is why the expression 'seems to promise something different' is used, though in actual fact it does not promise anything different. For the law from God is the law of order, and the law of order so far as those passing through a state of molestations by falsities are concerned is that they must be molested until they reach the point of despair. Unless they reach the point of despair the final advantage to be gained from molestation is lost. The fact that temptation grows ever stronger until a person reaches the point of despair is plainly evident from the Lord's temptation in Gethsemane, Matthew 26:38-39; Mark 14:33-36; Luke 22:44, and also after that on the Cross, Matthew 27:46, when it was made to reach the state of despair. Now the Lord's temptation is the pattern which the temptation of faithful believers follows, which is why the Lord says that those who wish to follow Him must take up their cross, Matthew 10:38; 16:24. For the glorification of the Lord is the pattern that the regeneration of man follows, 3138, 3212, 3296, 3490, 4402, 5688; and regeneration is effected chiefly by means of temptations.
