Yes. The fire of hell is a real and created fire, which will affect even the bodies of men who die at enmity with God. I grant that it will differ in various characteristics from natural fire as we know it. Christ chose the word fire as being that element best known to us which produces results most similar to the effects of the fire of hell. Yet fire as we know it depends upon combustion. The fire of hell will not depend upon being constantly fed with fuel, but upon God’s will, the principle of all existing things. If God can will that fire should exist with the aid of fuel to which He gave its properties, He certainly can produce and conserve fire by simply willing it, and without the aid of created fuel. Thus He manifested to Moses a bush in flames yet unconsumed.
