A fire which cannot be quenched, a worm which cannot die, I see existing, and consider them among the most blessed revelations of the gospel. I fancy I see them burning and devouring everywhere in the spiritual world, as their analogues do in the physical. I know that they have done so on me, and that their operation, though exquisitely painful, is most healthful. I see the world trying to quench and kill them; I know too well that I often do the same ineffectually. But, in the comfort that the worm cannot die and the fire cannot be quenched, I look calmly forward through endless ages to my own future, and the future of that world whereof it is written, "He shall reign until He hath put all enemies under His feet, and death and hell shall be cast into the lake of fire."

The Day of the Lord will be revealed in flaming fire, not merely to give new light and a day-spring from on high to those who sit in darkness and the shadow of death, but to burn up out of sight, and off the universe, the chaff, hay, and stubble which men have built on the One Living Foundation, Christ, in that unquenchable fire, of which it is written that Death and Hell shall one day be cast into it also, to share the fate of all other unnatural and abominable things, and God's universe be -- what it must be some day -- very good.

Because I believe in a God of absolute and unbounded love, therefore I believe in a loving anger of His, which will and must devour and destroy all which is decayed, monstrous, abortive, in His universe, till all enemies shall be put under His feet, to be pardoned surely, if they confess themselves in the wrong and open their eyes to the truth. And God shall be All in All. Those last are wide words.
