He speaks of the “fire that never shall be quenched.” Now, do not begin telling me that that is metaphorical fire: who cares for that? If a man were to threaten to give me a metaphorical blow on the head, I should care very little about it; he would be welcome to give me as many as he pleased.
And what say the wicked? “We do not care about metaphorical fires.” But they are real, sir—yes, as real as yourself. There is a real fire in hell, as truly as you have now a real body—a fire exactly like that which we have on earth in everything except this—that it will not consume, though it will torture you. You have seen the asbestos lying in the fire red hot, but when you take it out it is unconsumed.
So your body will be prepared by God in such a way that it will burn for ever without being consumed; it will lie, not as you consider, in metaphorical fire, but in actual flame.
