Just a thought: In the book of Deuteronomy God is called a consuming Fire (Deut 4:24), and we also know the that voice of God was heard from heaven through the fire. The lake of fire in the book of Revelation is associated with the second death, and the second death is the final Judgement. The scripture also tells us that they who are in Christ shall not be hurt of the second death, and that those who have part in the first resurrection, the second death hath no power. The scripture also tells us that those who are not in Christ, the son judges not, but the Judgement returns to the Father. So those whom it is said have prophesied in his name, and cast out demons in his name, and have done all of these wonderful works in his name, but in that day Jesus will say to them depart from me for I never knew you. They have not taken part in the first resurrection, so they face the second death. They face the lake of Fire. They face the Judgement seat of the Father, for God is a consuming fire. So ultimately when they go into the lake of fire, they are going back to God who created them.
