At what time they become warm, they vanish: when it is hot, they vanish out of their place.

33. For all persons that are ruled by concern for the present life, are brought to nought by the loss of it, and then they are undone without, who have for long been undone within by disregarding the things of eternity. Concerning whom it is rightly added, When they have become hot, they shall be dissolved from their place. For every wicked man when he ‘has become hot is dissolved from his place,’ in that, in drawing near to the Judgment of the Interior Severity, when he has now begun to be heated in the knowledge of his punishment, he is severed from that gratification of his flesh whereunto he had long time clung. Hence it is that it is delivered by the Prophet against the reprobate, And vexation alone shall only give understanding to the hearing [Is. 28, 19]; in that verily they never understand the things of eternity, saving when they are already made to undergo punishment for those of time without remedy. Thus the mind is heated, and inflames itself with the fires of a fruitless repentance, it shrinks from being led to punishment, and holds fast to the present life in desire, but it is dissolved from its place, in that panting from the gratification of the flesh, its hardness is melted by suffering chastisement. But seeing that we have heard what all the wicked will undergo in the hour of their removal, let us hear further some of the ways in which their course is perplexed in the career of their freedom.
