Personally, I’d happen to regard “hell” as referring to an eternal state, where persons will now eternally exist in unveiled God’s universe (presence?). To those who know and love God, existing eternally in such an unveiled presence of God will be bliss, as he or she will have been transformed into his (God’s) likeness, spiritually at our conversion and justification, and physically at Christ’s second coming (Romans 8:23). However, to those whose natures are fallen and unredeemed, the eternal existence of such people in the complete unveiled presence of God will produce intense pain and suffering, to varying degrees, dependent upon their own depravity and depths of sin in disharmony with the omnipresence existence of the holy (and sinless) God.
So, whilst I would personally hold to the position of “eternal conscious torment” for fallen unbelievers, in the (post-second coming) eternal state. None-the-less, I would also postulate as a possible explanation for this, that God himself does not actively punish or consciously torment these lost sinners, so therefore God is not himself responsible for the eternal sufferings of the lost which they will suffer eternally and also to varying degrees. As in my opinion, eternal conscious suffering is just the obvious result of God simply unveiling his presence to creation in the eternal state.
So I’d argue that the “fire,” and to the lake of fire, indicates God’s omnipresent unveiled presence; which produces pain in those who do not know God. At the present time God has actively veiled his presence, as without his presence being currently veiled, all persons across the world would instantly perceive God fully, thereby nullifying the need for faith (trust). So the riddle of hell isn’t that God is some sadist who actively tortures people, by some deliberate act of sadism. God has the complete right to unveil his presence from us, as this is his natural state, and when he does (eternally) unveil his presence, then the lost will suffer (eternally and also to varying degrees), from simply existing as sinful creatures in his presence. In doing so, God is not actively torturing people, God is passive, as it’s the sinner’s sin which causes their own pain and suffering in the presence of the unveiled holiness of God.
