What is the lake of fire?


And the devil, who deceived them, was thrown into the lake of burning sulfur, where the beast and the false prophet had been thrown. They will be tormented day and night for ever and ever. Revelation 20:10
Then death and Hades were thrown into the lake of fire. The lake of fire is the second death. Revelation 20:14
            The lake of fire is a reference to hell.  HELL in the Greek is geenna and it means a place of future punishment.  Jesus used the term eleven times.
            Strong’s Concordance says, Hell is the place of the future punishment call "Gehenna" or "Gehenna of fire". This was originally the valley of Hinnom, south of Jerusalem, where the filth and dead animals of the city were cast out and burned; a fit symbol of the wicked and their future destruction.
            Everyone who does not believe in Jesus or who caused others to not believe in Jesus will be thrown there, tossed away, where they will be persecuted.
