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.

133. However, the effect of miracles on good people is different from their effect on evil people. Good people have no desire for miracles, but they believe the miracles in the Word. If they do hear anything about a miracle, they think of it only as a minor argument that strengthens their faith, because they base their thinking on the Word and therefore on the Lord and not on the miracle.

It is different for evil people. They can actually be constrained and compelled to faith and even to worship and devotion by miracles. This lasts only a short while, though, because their evils are pent up inside, and the compulsions and gratifications of those evils are constantly working away inside their outward worship and devotion. In the effort to let them break free of this confinement, these people think about the miracle and wind up calling it a sham, a trick, or a natural event, which enables them to return to their evil ways. People who go back to their evil ways after being worshipful profane what is good and true in worship, and the fate after death of people who profane what is holy is the worst of all. These are the people referred to in the Lord's discourse in Matthew 12:43-44, 45, the people whose last state is worse than the first.

Besides, if miracles did happen for people who do not believe in the miracles in the Word, they would be happening constantly where everyone like this could see them. This shows why miracles do not happen nowadays.
