Alter2Ego,
Your questions can be most constructively pursued by addressing these 10 questions. It is past midnight on New Year's Eve. So I will simply pose these questions to see if there are enough intellectually curious and open-minded seekers on this site to motivate me to address them in detail biblically.
(1) "Shall mortal man be more just than God (Job 4:17)?"
What is your answer to this divine question to Job?
(2) If God is pure unconditional love, would His love not express itself through reformative postmortem justice rather than just retributive justice?
(3) If God is pure unconditional love and wants to save everyone, why should that divine quest be terminated by the sinner's death?
(4) Are you aware of the implied biblical teaching that Hell is like an educational mirror that teaches its denizens what life would be like in a realm based on the principle that like attracts like?
(5) Jesus' preferred word for "Hell" is "Gehenna." He prefers that word because He embraces the more hopeful and moral standard ancient rabbinic view of Hell. Have you considered the implications of this for your OP?
(6) Are you aware that in both Hebrew ("amunah") and Greek ("aionios") the word translated "eternal" often does not mean that? Can you see why this has implications for the morality of the standard evangelical belief in Hell?
(7) Are you aware the King James translation of "Sheol" as "Hell" is a mistranslation and that Sheol is not a realm of conscious intelligent existence?
(8) C. S. Lewis was one of the most respected evangelical authors of the 20th century. But he provocatively said, "The gates of Hell are locked from the inside." Do you know what he meant by that and what the biblical justification for his belief is?
(9) id you know that C. S. Lewis believed in Purgatory? Most Pentecostals dismiss Catholic doctrinal distinctives as false man-made church traditions and are blissfully ignorant of how Catholic apologetics seeks to justify these distinctives biblically. For example, do you know how an informed Catholics would justify their beliefs in Purgatory from Scripture? Do you see the relevance of this question to your OP?
(10) Are you aware of all the New Testament texts that teach the possibility of ultimate release from Hell?
