164. And them that commit adultery with her into great tribulation. That this signifies grievous temptations to those who give themselves up to their falsities is evident from the signification of committing adultery, as being to falsify truths (concerning which see above, 141); hence to commit adultery with Jezebel is to give themselves up to the falsities of those signified by Jezebel; and from the signification of tribulation as being infestation of truth by falsities (concerning which also see above, n. 47), in this case temptation, inasmuch as temptation is nothing else but infestation of truth by falsities with man (as may be seen in The Doctrine of the New Jerusalem 188, 196, 197). Therefore by casting those who commit adultery with her into great tribulation, is signified the grievous temptations of those who give themselves up to their falsities. The subject here treated of is those with whom the spiritual or internal man is not so much closed, because they are in some spiritual affection for truth, and yet suffer themselves to be led astray by those who are in the doctrine of falsities (as may be seen above, n. 162). Because these receive falsities into the memory of their natural man, with which the spiritual internal man cannot agree - for this receives nothing but truths - therefore a combat commences between the spiritual and the natural man: this combat is temptation, which is signified by great tribulation. (That temptation is a combat between the spiritual and natural man, may be seen in The Doctrine of the New Jerusalem 190, 194, 197, 199.)

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.
