7950. 'Even to the firstborn of the prisoner who was in the dungeon' means falsified truths of faith that occupy the last place of all. This is clear from the meaning of 'the firstborn in the land of Egypt' as faith separated from charity, as just above in 7948, and so also falsified truth of faith, dealt with below; and from the meaning of 'the prisoner who is in the dungeon' as those who occupy the last place of all, for his firstborn is placed at the opposite end of the scale from 'Pharaoh's firstborn who was to sit on his throne', which means falsified truth of faith that occupies the first place, 7779, 7949. 'The prisoner who is in the dungeon' is used to mean in the spiritual sense closest to the actual words one who thinks only on the level of his physical senses, and so is in utterly thick darkness so far as matters of truth and good are concerned; for he does not even possess the ability to perceive, as those who think on a more internal level of the senses do. This is the reason why those who occupy the last place of all are meant.

[2] The reason why 'the firstborn in the land of Egypt' means falsified truth of faith is that 'the firstborn of Egypt' is faith separated from charity, 7948; and those with this kind of faith are in nothing but complete and utter darkness so far as truths of faith are concerned. They cannot be in any light, and so cannot at all perceive what truth is or whether something is true. This is because all spiritual light comes from the Lord through good, that is, through charity. For the good of charity is like a flame from which light radiates, since good comes of love, and love is spiritual fire, the source of enlightenment. Anyone who imagines that people leading an evil life can also receive enlightenment in the truths of faith is very much mistaken. Their state may be such that they are able to produce proofs, that is, they may be able to prove the teachings of their Church, sometimes with skill and ingenuity; yet they are not able to see whether the things they prove are true or not. The fact that even falsity can be proved so adroitly that it seems to be the truth, and that a person is wise not when he can prove that something is right but when he can see whether it is, see 4741, 5033, 6865, 7011, 7680.

[3] Therefore a person whose life is sunk in evil is steeped in falsity arising from his evil; and no matter how well he knows what is true he does not believe it. Sometimes he thinks he does, but he is mistaken. He will be allowed to know in the next life that he does not believe it, when his perceiving is made to conform to his desiring. When that is done he will disown the truth, oppose it, and spurn it, and will acknowledge its opposite - falsity - as the truth. This now explains why those who are governed by faith separated from charity cannot help falsifying the truths of faith.

7778. 'And all the firstborn in the land of Egypt will die' means the damnation of faith separated from charity. This is clear from the meaning of 'dying' as damnation, dealt with in 5407, 6119; and from the meaning of 'the firstborn' as the Church's faith through which charity comes, dealt with in 352, 2435, 6344, 7035. But 'the firstborn in the land of Egypt' is faith devoid of charity, about which see above in 7766.

[2] As regards faith devoid of charity, there is more to be said. Faith that is devoid of charity is not faith but merely knowledge of such things as constitute faith. For the truths of faith look to charity as their ultimate end in view, and later on proceed from charity as their first end in view. From this it is evident that the things which constitute faith do not exist with those who have no charity, even though they have a knowledge of the truths of faith, as is well known. This knowledge is what they call faith. And when they use the facts they know about the truth and good of faith to support falsities and evils, they no longer have the truths and forms of the good of faith because these come to be like the falsities and evils that such truths and forms of good serve. For now the very falsities and evils which they support are seen in them.

[3] Things that constitute genuine faith look upwards to heaven and the Lord, whereas those that constitute faith separated from charity look downwards - and when they support evils and falsities - to hell, from which too it is evident that faith separated from charity is not faith. All this goes to show what is meant by the damnation of faith separated from charity, that is to say, of the truth of faith when falsified and the good of faith when adulterated. For when truth has been falsified it is no longer truth but falsity, and when good has been adulterated it is no longer good but evil; and faith itself is no longer faith composed of truth and good but of falsity and evil, no matter what it looks and sounds like to outward appearance. Furthermore, and this is an arcanum, the character of anyone's faith is determined by the character of his life. If therefore his life is damned, so is his faith; for it is a faith composed of falsity when his life is a life of evil. It is not apparent in the world that this is so, but it is made plain in the next life. When the evil in that life are deprived of the truth and good they know there then emerge from evils the falsities which have lain hidden with those people.

[4] With some evil people a certain kind of conviction exists that the truth of faith is the truth; and this conviction too is thought to be faith. But it is not faith since it is induced by the intent to make it serve as the means by which wealth, important positions, and reputation can be acquired. As long as the truths they know are serving as the means to that end they love them for the sake of an evil intent. But when they no longer serve in that way they are abandoned, indeed are regarded as falsities. The term 'persuasive faith' is used to describe this kind of conviction, and it is what is meant by the Lord's words in Matthew,

Many will say to Me on that day, Lord, Lord, did we not prophesy though Your name, and through Your name cast out demons, and do many mighty works in Your name? But then I will confess to them, I do not know you; depart from Me, you workers of iniquity. Matthew 7:22-23.

The same kind of faith is also meant by 'lamps without oil' with the five foolish virgins, who also said, Lord, Lord, open to us. But He replying said, Truly, I say to you, I do not know you. Matthew 25:11-12.

The truths of faith are meant by 'lamps', and the good of charity by 'oil', so that 'lamps without oil' are truths of faith devoid of the good of charity.
