There are many men, who form good hopes not by abstaining from their sins, but by thinking that hell is not so terrible as it is said to be, but milder than what is threatened, and temporary, not eternal; and about this they philosophize much. But I could show from many reasons, and conclude from the very expressions concerning hell, that it is not only not milder, but much more terrible than is threatened. But I do not now intend to discourse concerning these things. For the fear even from bare words is sufficient, though we do not fully unfold their meaning. But that it is not temporary, hear Paul now saying, concerning those who know not God, and who do not believe in the Gospel, that
“they shall suffer punishment, even eternal destruction.”
How then is that temporary which is everlasting?
“From the face of the Lord,” he says.
What is this? He here wishes to say how easily it might be. For since they were then much puffed up, there is no need, he says, of much trouble; it is enough that God comes and is seen, and all are involved in punishment and vengeance. His coming only to some indeed will be Light, but to others vengeance.
