Burning the chaff with UNEXTINGUISHED fire

As a further evidence for what I said in post on the unquenched fire, here is what Jesus said. He said there is chaff which shall be burnt with UNEXTINGUISHED fire.
See Mt. 3:12, Lu. 3:17

Well, this makes a case for the "fire" of the Lake of Fire which consumes until there is no more fuel to burn, at which time the pain ceases.

The alternate view of Isaiah 66:24 - that the fire of the man is his own spirit and not an outside force - is still appropriate for Isaiah 66:24, but not for the "fire" of Gehenna or the "fire" of the Lake of Fire.
