453. Verse 18. By these three was a third part of men killed, by the fire, and by the smoke, and by the brimstone, that issued out of their mouths, signifies that it is from these that the men of the church perish. "A third part of men being killed," signifies that the men of the church perish by the three things just now mentioned (n. 452); for by "being killed" is signified to be killed spiritually, which is to perish as to the soul; and by "a third part" is signified all who are in those falsities, which have been frequently enumerated above; what is signified by "fire," "smoke," and "brimstone," and what by "issuing out of their mouths," may be seen above (n. 452). It is from these falsities, that in the whole Christian world it is not known that "fire" here spoken of is the love of self and of the world, and that this love is the Devil; also that "the smoke" from this fire is the pride of one's own intelligence, and that this pride is Satan; as also that "brimstone" kindled by this fire, by means of that pride, is the lusts of evil and falsity; and that these lusts are the crew of the Devil and Satan, of which hell consists; and when these things are not known, it cannot be known what sin is, for sin derives all its delight and pleasantness from them.
