251. The reason why the “serpent” means all evil in general, and specifically the love of self, is that all evil has had its rise from that sensuous part of the mind, and also from that memory-knowledge [scientifico], which at first were signified by the “serpent;” and therefore it here denotes evil of every kind, and specifically the love of self, or hatred against the neighbor and the Lord, which is the same thing. As this evil or hatred was various, consisting of numerous genera and still more numerous species, it is described in the Word by various kinds of serpents, as “snakes” “cockatrices” “asps” “adders” “fiery serpents” “serpents that fly” and “that creep” and “vipers” according to the differences of the poison, which is hatred. Thus we read in Isaiah:

Rejoice not thou, whole Philistia, because the rod which smiteth thee is broken, for out of the serpent’s root shall go forth a cockatrice, and his fruit shall be a flying fire-serpent (Isaiah 14:29).The “serpent’s root” denotes that part of the mind, or that principle, which is connected with the senses and with memory-knowledge [est sensuale et scientificum]; the “cockatrice” denotes evil originating in the falsity thence derived; and the “flying fire-serpent” the cupidity that comes from the love of self. By the same Prophet also similar things are elsewhere thus described:

They hatch cockatrice’s eggs, and weave the spider’s web; he that eateth of their eggs dieth, and when it is crushed there cometh out a viper (Isaiah 59:5).

The serpent described here in Genesis is called in the Revelation the “great and red dragon” and the “old serpent” and also the “devil and satan” that “deceives the whole world” (Revelation 12:3, 9; 20:2), where, and also in other places, by the “devil” is not meant any particular devil who is prince over the others, but the whole crew of evil spirits, and evil itself.

2261. 'If I find in Sodom fifty righteous persons in the midst of the city' means if truths are full of goods. This is clear from the meaning of 'fifty' as that which is full, and from the meaning of 'the midst of the city' as that which is present inwardly, or within truth, dealt with above in 2252, which see since the same words occur there. It may be assumed that a person is certain to be saved if truths are full of goods. But it should be recognized that very few truths exist with man; and if they do, that they have no life unless there are goods within them; and if they have goods within them, that he is saved, but on account of mercy. For as has been stated, very few truths reside with a person, and the goods contained within them receive their character from the truths and from that person's life.

[2] Regarded in themselves truths do not confer life; but goods do so. Truths are simply the recipients of life, that is, of good. Nobody is ever able to say therefore that he can be saved by means of truths or as is commonly asserted, by faith alone - not, that is, unless within the truths, which are part of the faith, good is present. And this good which must exist within them must be the good that flows from charity. This explains why in the internal sense faith itself is nothing else than charity, as shown above in 2231. When people say that the acknowledgement of truth is the faith that saves, it should be recognized that no acknowledgement can possibly exist with people who lead lives immersed in things contrary to charity, only some kind of persuasion which has the life of self-love or of the love of the world allied to it, so that the acknowledgement which they speak of does not have within it the life of the faith which is that of charity. The worst people of all, acting from self-love or from love of the world, that is, acting for the sake of excelling others in what are called intelligence and wisdom, and so acting for the sake of earning exalted positions, reputation, and gain, have the ability to grasp the truths of faith and to confirm them in many ways; but with them those truths are nevertheless dead. The life of truth and so of faith comes solely from the Lord, who is Life itself.

[3] The Lord's life is mercy, which is that of love towards the whole human race. Those people cannot possibly be drawing on the life that is the Lord's who, although they profess the truths of faith, despise others in comparison with themselves, and who, where their self-love and love of the world are affected, harbour hatred towards the neighbour and are delighted when he experiences loss of wealth, position, reputation, and life. But the position with the truths of faith is that it is by means of them that one is regenerated, for they are the actual vessels for receiving good. As are the truths therefore, also the goods within those truths, and the combination of those truths and goods and from this their capacity to be perfected in the next life, so is the state of blessedness and happiness of that person after death.
