751. Therefore rejoice, ye heavens, and ye that dwell in them.- That this signifies the salvation and consequent joy of those who become spiritual by the reception of Divine Truth, is evident from the signification of rejoicing, as denoting joy on account of salvation; from the signification of the heavens, as denoting those who are spiritual (concerning which we shall speak presently); and from the signification of ye that dwell, as denoting those who live, here spiritually. That to dwell signifies to live, may be seen above (n. 133, 479, 662). The heavens signify those who are spiritual, because all who are in the heavens are spiritual, and because men who have become spiritual are also in the heavens, although they are in the world as to the body; therefore ye that dwell in the heavens means not only angels, but also men, for every man with whom the interior mind, which is called the spiritual mind, has been opened, is in the heavens, indeed, he also sometimes appears amongst the angels there. That this is so, has not been known in the world up to the present time. It must therefore be understood, that man as to his spirit is among spirits and angels, and indeed in that society of them into which he is to come after death. The reason of this is that the spiritual mind of man is formed exactly according to the image of heaven, and in such a way that it is a heaven in least form; consequently that mind, although still in the body, must nevertheless be where its form is. But this has been more fully dealt with in Heaven and Hell 51-58), where it is shown that every angel, and also every man as to his interiors, if he be spiritual, is a heaven in its least form, corresponding to heaven in its greatest form. For this reason where the Word treats of the creation of heaven and earth, the internal and external church is in general meant, and, in particular, the internal and external man, that is the spiritual and natural man. From these things it is evident that the heavens and those that dwell in them signify all who are there, and also those men who are becoming spiritual by the reception of Divine Truth in doctrine and life.

1692. What temptations, or the conflicts that constitute temptations, accomplish, scarcely anyone is able to know. They are the means by which evils and falsities are broken up and dispersed. They are also the means by which an abhorrence of these is produced, and a conscience is not only given but also strengthened, and man is accordingly regenerated. This is the reason why those who are being regenerated are led into conflicts and undergo temptations and why those who do not experience them during their earthly life do so in the next life, provided they are such as can be regenerated. And it is for these reasons also that the Lord's Church is called 'militant'. The Lord alone however underwent from His own strength or power the most cruel conflicts that constitute temptations, for He was beset by all the hells and constantly overcame them.

[2] It is also the Lord alone who fights in the temptation-conflicts of those who do undergo these. Man by his own power can accomplish nothing in the slightest against evil or hellish spirits, for they are so closely linked to the hells that if one were vanquished another would rush to take his place, and so on for ever. They are like the sea pressing against every part of a dike. If the dike were to develop a split or crack the sea would never cease to pour through and flood the land until nothing was left standing. It would be like this with man if the Lord alone did not bear up against the conflicts experienced by man in temptations.
