1820. 'By what shall I know that I shall inherit it?' means temptation directed against the Lord's love which wished to be made quite certain of the outcome. This becomes clear from the feeling of doubt which the words express. Anyone who is undergoing temptation experiences doubt as regards the end in view. That end is the love against which evil spirits and evil genii fight and in so doing place the end in doubt. And the greater his love is, the more they place it in doubt. Unless the end in view which a person loves is placed in doubt, and even in despair, there would be no temptation. A feeling of certainty about the outcome precedes, and is part of, victory.

[2] Since few people know what temptations really are, let a brief explanation of them be given here. Evil spirits never contend against any other things than those which a person loves, and the more intensely he loves them the more fiercely do those spirits contend. Evil genii are the ones that contend against the things of affection for what is good, and evil spirits are the ones that do so against the affection for what is true. As soon as they detect even the smallest thing that a person loves or get a scent, so to speak, of what is delightful and precious to him, they attack it instantly and try to destroy it, and so the whole person, since his life consists in his loves. Nothing ever gives them greater delight than to destroy a person; nor would they leave off but would continue even for ever, if the Lord did not drive them away. Those who are ill-disposed and deceitful worm their way into those very loves by flattering them, and in this way they bring a person in among themselves. And once they have so brought him in, they very soon try to destroy his loves and so to slay that person, which they do in a thousand unimaginable ways.

[3] Nor are the attacks which they make solely those in which they reason against goods and truths - the making of such attacks being nothing to them, for if they were defeated a thousand times over they would carry on with them because their supply of reasonings against goods and truths can never be exhausted. Rather, in their attacks, they pervert goods and truths, setting these ablaze with a certain kind of evil desire and of persuasion, so that the person himself does not know any other than that similar desire and persuasion reign within him. At the same time they infuse those goods and truths with delight which they seize from the delight which that person has in some other thing. In these ways they infect and infest him most deceitfully, doing it all so skillfully by leading him from the one thing to another that if the Lord did not come to his aid, that person would never know other than that it was indeed so.

[4] They act in similar ways against the affections for truth that constitute conscience. As soon as they become aware of anything, whatever the nature of it, that is a constituent part of that conscience, they mould an affection out of the falsities and weaknesses that exist with that person, and by means of that affection they dim the light of truth and so pervert it, or else they cause him anxiety and torment. In addition to this they keep his thought firmly fixed on one single thing; and they fill that thought with delusions, at the same time secretly incorporating evil desires within those delusions. Besides this they use countless other devices which cannot possibly be described so as to be understood. These are a few of the ways - and only very general ones - by which they are able to get at a person's conscience, which above all else they take the greatest delight in destroying.

[5] These few, indeed very few, observations show the nature of temptations - in general that the nature of a person's temptations is as the nature of his loves. They also show the nature of the Lord's temptations, that these were the most dreadful of all, for as is the intensity of the love so is the dreadfulness of the temptations. The Lord's love - a most ardent love - was the salvation of the whole human race; it was therefore a total affection for good and affection for truth in the highest degree. Against these all the hells contended, employing the most malicious forms of guile and venom, but the Lord nevertheless conquered them all by His own power. Victories have this effect, that after they have been won, wicked genii and spirits do not dare to attempt anything; for their life consists in their being able to destroy, but when they perceive that a person is able to withstand them, they flee even when they are making their first assault, as they usually do when they draw near to merely the threshold of heaven. They are straightaway gripped with horror and dread and hurl themselves back in retreat.

4307. In the internal historical sense 'Jacob asked and said, Tell me, I pray, your name' means evil spirits. This becomes clear from many connections in this sense, in which these words and those that follow have reference to the descendants of Jacob; for the meaning in the internal sense depends on the specific subject under discussion. For not good spirits but evil ones are meant by him who wrestled with Jacob, as becomes clear from the consideration that 'wrestling' means temptation, 3927, 3928, 4274; and no temptation is ever carried out by good spirits, only by evil ones. For temptation consists in the activation of the evil and falsity residing with a person, 741, 751, 761, 1820, 4249, 4299. Good spirits and angels never activate evils and falsities but defend a person against them and turn them to good; for good spirits are led by the Lord, and from the Lord nothing except holy good and holy truth ever proceeds. The Lord does not tempt anyone, as is well known from teaching accepted in the Church; see also 1875, 2768. From this and also from the fact that the descendants of Jacob gave in to every temptation not only in the desert but also after that, it is evident that they were not good spirits but evil ones who are meant by him who wrestled with Jacob. What is more, the nation meant by 'Jacob' here was not governed by any spiritual or celestial love, only by bodily and worldly love, 4281, 4288-4290, 4293. The spirits present with any people depend on the loves governing those people, good spirits and angels being present with those who are governed by spiritual or celestial love, evil spirits with those who are governed solely by bodily or worldly love. So true is this that anyone can know which kind of spirits are present with him merely by noting the nature of his own loves, or what amounts to the same, the nature of his ends in view, since everyone has that which he loves as his end in view.

[2] The reason the one who wrestled with him called himself 'God' is Jacob's own belief that he was. In this he was like his descendants who believed unceasingly that Jehovah was present in their holy external observances, when in fact Jehovah was present solely in what these represented, as will be clear from what follows below. They also believed that Jehovah led them into temptations, was the author of all evil, and was full of anger and fury whenever they were punished. It is because they believed He was like this that such descriptions of Him appear in the Word, when in actual fact Jehovah never leads anyone into temptations, is never the author of anything evil, and is never full of anger, still less of fury, see 223, 245, 592, 696, 1093, 1683, 1874, 1875, 2395, 3605, 3607, 3614. This also explains why the one who wrestled with Jacob was unwilling to reveal his name. The reason why in the internal spiritual sense the one who wrestled with Jacob is used to mean the angelic heaven, 4295, is that the Lord, who in the highest sense is there represented by 'Jacob', allowed even angels to enter in and tempt Him, and that the angels were in that case left alone to their proprium, as has been shown in the paragraph just referred to.
