The following is by J. Preston Eby

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 apostate Churches say about it, nor what tradition says about it; but I certainly believe what the Bible says about it.
The teaching concerning the lake of fire does not appear anywhere in Scripture except in the book of Revelation where it is spoken of in the following passages: Rev. 14:10-11; 19:20; 20:10; 20:13-15 and 21:8. This last passage definitely states, "But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolators, and all liars shall have their part in the lake which burns with fire and brimstone: which is the second death."

There should be no question remaining as to the certainty of this lake of fire; neither should there be any doubt as to the awful consequence of having to be cast into it. These Scriptures with their dreadful foreboding should be a fearful warning to all unthinking and foolish people who, because of their love for the world, the flesh, and the devil, have dared to ask why we should serve God now if all are going to be saved eventually. Such people have no love for God nor fear of God, and they manifest by what they say that their professed serving of God is only a pretense, arising - not from any true love for Him - but from fear of punishment. If there were no prospect of hell these would promptly tell God to go to hell and they would, themselves, go to the devil. It is not thus with those who truly love God, for they serve not from fear, but from pure love and devotion. Remove punishment completely from the universe, and they would still serve God with all their hearts.

Because of the gross misunderstanding of almost all people concerning the lake of fire, I would like to draw your attention to three words found in the passage quoted above. "But the fearful, and unbelieving, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars shall have their part in the lake which BURNS with FIRE and BRIMSTONE: which is the second death."

The word BURN means combustion, or to consume. To consume does not mean to annihilate, for there is no such thing as annihilation in the absolute sense. When fire consumes a log in your fireplace it does not destroy any of the elements within the log, it merely changes their form. Combustion is the process by which chemicals combine to form new chemicals. For example: a tree might be cut down, sawed into fire wood, and burned. When the wood is burning the heat causes the chemicals of which the wood is composed to vaporize, mixing with the oxygen in the air to form new chemicals, including water and the gas carbon dioxide. So what was formerly a tree is no longer identified as the form of a tree, but the substance thereof is now simply CHANGED into a DIFFERENT FORM and exists in its new form within the atmosphere as water, carbon dioxide, etc. Thus, to bum, means to CHANGE. Furthermore, it is interesting to note that fire does not burn down; it always burns up; it seeks the highest level. And all that it consumes "goes up in smoke," to exist in a new form in a higher dimension. Even if you take a pan of water and place it over a fire, before long the water will take on the property of the fire and will begin to go up in steam. To burn means to CHANGE, and the change is always UPWARD in its motion.

FIRE is the heat and light that you feel and see when something burns. It takes heat to start a fire, but once the fire is started it produces heat that keeps the process going. Thus, fire is really HEAT and LIGHT.In my study of the lake that burns with fire and brimstone I was very much helped and impressed by the understanding given by Charles Pridgeon and I would like to quote from his scholarly work on the subject of BRIMSTONE. He says: "The Lake of Fire and Brimstone signifies a fire burning with brimstone; the word 'brimstone' or sulphur defines the character of the fire. The Greek word THEION translated 'brimstone' is exactly the same word THEION which means 'divine.' Sulphur was sacred to the deity among the ancient Greeks; and was used to fumigate, to purify, and to cleanse and consecrate to the deity; for this purpose they burned it in their incense. 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.' The idea of judgment need not be excluded. Divine purification and divine consecration are the plain meaning in ancient Greek. In the ordinary explanation, this fundamental meaning of the word is entirely left out, and nothing but eternal torment is associated with it" -end quote.

I realize that the above thoughts define the subject very briefly, but let us summarize the meanings thus: 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 AND LIGHT PRODUCING A CHANGE! Is such a process eternal? All the laws of nature shout that it is not!
More than 2500 years ago the Holy Spirit warned the wicked inhabitants of Jerusalem that God would kindle a fire at Jerusalem's gates which would devour her palaces. "But if you will not hearken unto Me ... then will I kindle a fire in the gates thereof, and it shall devour the palaces of Jerusalem, and it shall not he quenched" (Jer. 17:27). Did not God say this fire "shall NOT BE QUENCHED?" This prophecy was fulfilled and the fire did occur a few years later and it did destroy all the houses of Jerusalem (Jer. 52:13). Since God said no person or thing would "quench" this fire, did that mean that it would burn for ever? Since it accomplished the work it was sent to do, and since it is NOT BURNING TODAY, it obviously went out by itself after accomplishing its purpose!

Unquenchable fire is not eternal fire - it is simply fire that cannot be put out until it has consumed or changed everything it is possible for it to change! It then simply goes out, for there is nothing more to burn. Yet I hear the preachers ranting and raving about poor souls being cast into bell fire where "their worm dies not, and the fire is not quenched" and this, we are told, means eternal, unending torment. How foolish, illogical, and deceptive! Such a view contradicts the plain meaning of the term "unquenchable" and its use in the Word of God.

Are the judgments of God permanent? Isaiah says, "When Your judgments are in the earth, the inhabitants of the world will learn righteousness" (Isa. 26:9). And Mat. 12:20 says, "A bruised reed shall He not break, and smoking flax shall He not quench, till He send forth judgment unto victory." Judgment, therefore, is not an eternal condition, but it is given to produce that victory. Judgments of themselves do not save anyone, but they are used by God to bring one to one's self, to effect a change of attitude and will, to consume away the stubbornness and rebellion of men. Punishment by fire is a beneficent one. "Our GOD is a consuming fire" (Heb. 12:29).

The basic purpose of this divine fire of God is to cleanse, purify, purge, temper and change. It is to rid of impurities, of filth, of undesirable elements. There is no better way to deal with filth than to deal with it by fire.The punishment by penal fire leads back to the beginning of things. The final work of God in this world will be the destruction of the world (order) by penal fire. That will change all things. That will melt all the elements, so that no man can tell you where his original grab was. It will burn up all the governments, institutions, systems, and fruitage of the carnal mind. It will melt all the customs, cultures, traditions, and practices of society and make of this earth a new earth wherein dwells righteousness. Every man's work will eventually be tested in this fire. The fire will try every man's work of what sort it is. If you and I build into our walls wood, hay, and stubble, that fire will find it out, and the wall will come tumbling down.
When God turns on the HEAT, the BLAZING LIGHT OF HIS SPIRIT AND WORD - some things begin to change! The fire is never sent to destroy the PERSON, but to purge out all that hinders and separates him from his God, to consume the pride, arrogance, hostility, defiance, and rebellion of the flesh, the carnal mind, that He might then be wooed and drawn by the Holy Spirit unto the Father of Spirits and live.

More than three centuries ago when the Black Plague swept through London, England, more than 68,000 men, women, and children were sickened with the putrid fever, suffered nameless agonies, passed into delirium, sometimes with convulsions, and then died. Before the end of the terrible nightmare of anguish and death, what was thought to be an even greater tragedy occured. The city caught fire, the whole heavens were ablaze as the Great Fire destroyed more than 13,200 homes and 89 churches. Most of the city, which was built largely of wood, lay in ashes. Wonder of wonders! As soon as the last dying embers cooled and the smoke cleared, the inhabitants of the city discovered that the Plague had been stayed! Not another person died of the epidemic. The Plague never returned. The fire had killed the bacteria-carrying fleas and rats that caused the Plague. It took a fire to do it!

Fire is a great cleanser, purifier, and changer.We all know that a horse must be broken, that is, its will must be broken before it is of any practical use to man. God put that will in the horse, but it must be broken and made to conform to the will of man. Just as surely did God put the will in man, BUT IT MUST BE BROKEN and we will benefit by the very process of breaking. Man may do a lot of crying and wailing, but when he is broken to HIS will, what a wonderful condition it is. God may take man over some rough places, even through the lake of fire and brimstone, but the love of God will break every man to His will.If you think the Kingdom of God is rosewater, or eau-de-cologne, you are mistaken. You cannot war on the devil with that. You cannot war on the carnal minds of men with that. You have to make war on the world, the flesh, and the devil with a sword sharper than any twoedged sword. You have to make war on the carnal mind with fire, divine fire that must burn up every inherent altar of Baal, and lick up the very dust around.
Make no mistake! OUR GOD is a consuming fire! He is man's "horse breaker" and He will break you, precious friend of mine, and bring you to the foot of the cross of Jesus no matter how hot He has to build the fire around you! Even if long ages of fiery judgment and tormenting darkness fall upon you, they will last no longer than till the Great Fire of God has melted all arrogance into humility, and all that is self has died in the bloody sweat and all-saving cross of the Christ, which will never give up its redeeming power till sin and sinners have no more a name among the creatures of God.
