I would agree with Goodlife on this. I was taught that hell is just the common grave of mankind. In fact I read somewhere (can't remember where) that the church of England is now re-assessing this doctrine.
Actually the word “hellfire” is an English distortion of “Gehenna,” this is the name of the refuse dump outside the city walls of Jerusalem. This is where the Jews burnt their rubbish and the bodies of criminals which were not considered worthy of a burial place. Jesus used this at Matthew 10 v 28 as a symbol of everlasting destruction.
Hell is translated from the Hebrew "Sheol" and Greek "Hades", and means the grave.
