Ken, it is interesting that you mentioned the lake of fire from Revelations. Firstly, Revelations is based for a large part on imagery and metaphor. I'm not saying the either of these is less truthful than any other means of communication, I simply state that it is generally accepted to be as such. Secondly, if you take a look throughout the Bible, what do you find that is eternal and fire? I'll save you a look and tell you that it is God. God appears as and uses fire numerous times in the Old Testament. Fire was also understood by the Jewish people as a purifier, a way in which one was made clean. So, some take the eternal lake of fire to be the purifying nature of God which come upon all those whose whose "name was not found written in the book of life" Rev 20:14. If you look at Rev 20:14-15 you can see it reads like this:
14 Then death and Hades were thrown into the lake of fire. The lake of fire is the second death. 15 If anyone's name was not found written in the book of life, he was thrown into the lake of fire.
If the lake of fire is Hell, then why is Hades (which is also translated into Hell throughout the New Testament) thrust into it. Hell goes to Hell?
Anyways, a few points to think upon.
