Ok, fair enough, fortigurn.
So your argument regarding the lake of fire really boils down to the fact that it is not explicitly stated in Revelation that persons cast into it come out of it. this is not much of an argument against our position, although you are correct in that the burden of proof is on us.
Well no, my argument is both positive and negative - nothing comes out of the lake of fire (negative), and that which goes in is demonstrably destroyed (positive).
There are, as far as I have gathered, two types of universalist explanation of this.
The first is the one I have put forth in this thread, namely that cotext and context indicate that the fire is purgatorial for the people who go into it.
It does not appear purgatorial in that it is the means by which death and the grave are destroyed.
The second is that those destroyed in the lake of fire will finally be resurrected in Christ.
The second has the problem of being complete speculation without any supporting evidence.
In defense of the first, I note that the context involves
a.) typical fire imagery - which always connotes purification (and we know that purification invovles destruction)
Fire imagery does not always connote purification, and the only contextual indicator for the function of this fire is the complete anihilation of death and the grave. That illustrates beyond doubt that the fire here is entirely destructive, not purifying.
b.) two Greek words (THEION and BASANIZO) used in conjunction, both which have purificatory connotations
Not in this context.
I also note that there are many verses which have all appearances of teaching universal reconciliation, thus affording the possibility that we are to shape our understanding of the lake of fire on these verses, rather than shaping our understanding of the UR verses on the lake of fire passages.
I note that this passage fits exactly the many eschatological passages in the Old and New Testament which speak of an everlasting reward for the righteous, an everlasting punishment for the wicked, and are utterly silent on the subject of a final release, rehabilitation, and reward of the wicked (see Daniel 12:2 and Matthew 25 for example).
