4274. 'And a man wrestled with him' means temptation that concerns truth. This is clear from the meaning of 'wrestling' as temptation. Temptation itself is nothing other than a wrestling or conflict, for truth is attacked by the evil spirits and defended by the angels who are present with a person. And his awareness of that conflict taking place within himself is temptation, 741, 757, 761, 1661, 3927, 4249, 4256. But no temptation can arise unless the good of truth, that is, the love or affection for truth, exists in him. For anyone who does not love the truth he knows, or is not affected by it, does not trouble about it at all, whereas anyone who does love it is worried lest it should suffer harm. Nothing else constitutes the life in a person's understanding than that which he believes to be the truth, and nothing else the life of his will than that which, he has become convinced, is good. This being so, when that which he believes to be the truth is attacked the life of his understanding is attacked; and when that which, he has become convinced, is good is attacked the life of his will is attacked. And therefore when a person is being tempted his life is under attack.

[2] The reason why the conflict at first concerns truth or is about truth is that truth is what a person loves first. That which anyone loves is the object of evil spirits' attack, but once he starts to love good more than truth, which takes place when order is being turned around, the temptation of him concerns good. But few know what temptation is, because few at the present day undergo any temptation; for none are able to be tempted except those who are governed by the good of faith, that is, by charity towards the neighbour. If those who are not governed by such charity experienced temptation they would instantly give way; and in those who give way evil becomes more firmly established and falsity more firmly believed, because in their case the evil spirits with whom they are thereby associated are victorious. This is the reason why at the present day few are allowed to enter into any spiritual temptation, but only into some natural forms of distress in order that they may be held back by means of them from self-love and love of the world into which they would otherwise plunge without any restraint.
