It may have been shared but here it is again.
The fact is that eternal fire does not mean a fire that will never go out. The same expression is used in Jude 7 concerning the destruction of Sodom and Gomorrha. "Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth as an example, suffering the vengeance of eternal fire."
It is quite obvious that Sodom is not still burning today. The Dead Sea rolls over the place where those ancient cities once stood. Yet they burned with "eternal fire," and we are told that it was an example of something. What is it an example of? "And turning the cities of Sodom and Gomorrha into ashes condemned them with an overthrow, making them an ensample unto those that after should live ungodly." 2 Peter 2:6.
There it is! That eternal fire which brought Sodom to ashes is an example of what will finally happen to the wicked. If this text is true, the same kind of fire that destroyed Sodom and Gomorrha will also burn the wicked in the lake of fire. Does that mean it will also burn the wicked to ashes?
