"I believe every word that the Bible says about the lake of fire; I don’t believe what Rome says about it, nor what the church systems of man say about it, nor what tradition says about it, nor what Chuck Johnel says about it; but I certainly believe what the Bible says about it!"
"One would think that the lake of fire was a prominent theme throughout the scriptures from the book of Genesis to the book of Revelation. It is not. The fact is that the teaching concerning the lake of fire and brimstone does not appear anywhere in scripture except in the book of Revelation, the book with the most signs, symbols, and metaphors of any book in the entire Bible. If the book of Revelation had not been given us we would have no knowledge of the lake of fire at all. The Revelation speaks of the lake of fire five times."
Much more in the link:
"In Homer’s Iliad (16:228), one is spoken of as purifying a goblet with fire and brimstone. The verb derived from theion is theioo which means to hallow, to make divine, or to dedicate to a god (See Liddell and Scott Greek-English Lexicon, 1897 Edition)."
"To any Greek, or any trained in the Greek language, a ‘lake of fire and brimstone’ would mean a ‘lake of divine purification."
"BURN means combustion; to change the form of. FIRE means heat and light. BRIMSTONE means divine. Putting these three together can we not see that the lake burning with fire and brimstone is, actually, DIVINE HEAT (JUDGMENT) AND LIGHT (ILLUMINATION) PRODUCING A CHANGE! Is such a process eternal? All the laws of nature shout that it is not!"
