It’s both! We know He is a consuming/purifying fire. (LOF as symbol of that spiritual, yet literal, truth.)
Soberly looking at WHERE in Revelation lake of fire is mentioned - and Jude 7 saying it is NOT a place:
#1 mention, is at fiery armageddon during which the Lord returns (aka, manmade, therefor is earthly prophecy like the rest of the book). #2 mention is at the final defeat of the adversary, beFore the resurrection of all not yet saved before their death. And #3 mention is at the “all made new” event when “the elements melt with furious, consuming heat and there is a new heavens and Earth where rightness will dwell” God now being “all in all” and “will TABERNACLE with mankind upon Earth”.
“The bear will graze with the cow, the lion will eat straw like the ox” (Is.11:7).
And note this! Yhvh/God Most High has given us the outline of the Son’s long second advent. TRUMPETS (sound) then 10days/1000yrs (yes? see the calendar of Lev.23). Followed by DAY oF ATONEMENT (DOA for the - initially - doa) consisting of 500yrs (represented by 5days, Lev.23).
And then! “God will now TABERNACLE with mankind upon Earth made anew” (after the re-genesis). Any not by then experiencing the 3 R’s (repentance, reconciliation, renewal) will experience it during that “all made new” event (called the 2nd death?) when “the elements will melt in furious heat” (lake of fire made for dragon&co).
Lev.23; [[2Pet.3:12-13-#3 lake of fire - 2Pet.3:10 being #1 lake of fire (the two being like bookends outlining the long 2nd advent)]]
Rev.20 & 21:1-5; 1Cor.15:(22-)28; Jude7, see Is.24:20! Is.11:7see Mic.4:3-4
The Lord said “all those in the tombs” (graves) “will hear His voice and will come forth ..some in the resurrection of life, and some in the resurrection of judgment” (Jn.5:28-29). Which is “after the thousand years” (Rev.20:5).
And he said, Matthew 25:46 - “these will rise into aionian-kolasis *AGE*LasTing-CORRECTION” (translated, everlasting punishment) “but the righteous into aionian life” (the millennium, called THE age).
