The idea of eternal conscious torment is one of those traditions carried over from medieval Catholicism (ultimately coming from Greek philosophy) that's heavily defended in Protestantism but not really taught in Scripture, or if it is, not plainly, as it is only inferred from certain expressions like "unquenchable fire" which speaks of the fire being unquenchable but does not say it will not burn anyone up. It can be defended with proof-texts to be sure, but is it explicitly and clearly taught? No. The annihilation of the souls of the wicked, however, is explicitly taught in at least two verses: 0 vs 2.
In large part the idea of eternal conscious torment in hell is based on the Platonic concept of the natural immortality of the soul. Plato and the Platonizing "church fathers" believed the soul to be so immortal by its very nature that God could not destroy it even if he wanted to. The result is that all God can do with the souls of the wicked in this philosophy is to dump them somewhere for all eternity. (In Platonism the soul was conceived as actually being a breakaway from God's substance or essence, thus sharing the nature of God and indestructible.)
But does scripture teach the natural immortality of the soul, or does it teach that souls are only immortal so long as God deems them to be so by his will?
1 Timothy 6:15-16 NIV "which God will bring about in his own time—God, the blessed and only Ruler, the King of kings and Lord of lords, who alone is immortal and who lives in unapproachable light, whom no one has seen or can see. To him be honor and might forever. Amen."
According to Scripture, God alone is immortal by nature. The soul then is only conditionally immortal. That is, only immortal if God says so. That means the biggest presupposition that caused the "church fathers" to develop the theory of eternal conscious torment is false, according to scripture.
Once you understand that, you will find a different story in Jesus' sayings on the subject. You will be free from the tyranny of Platonic philosophy and tradition based thereon, which before prevented you from taking Jesus at his word when he said:
Matthew 10:28 NIV "Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell."
He said "destroy" but tradition has always forced us to interpret "destroy" as "torment"! If we re-evaluate the tradition, and correct the root problem (Platonic misunderstanding of the nature of the soul) we no longer have to force ourselves to misinterpret the Bible in this way.
There's an entire website dedicated to a growing movement of Protestants who are Rethinking Hell, which is the name of the site: http://rethinkinghell.com/
And furthermore, there is one verse in the Bible that positively clinches the case by explicitly stating the wicked will be devoured by fire:
But the wicked shall perish, and the enemies of the Lord shall be as the fat of lambs: they shall consume; into smoke shall they consume away. (Psalm 37:20 KJV)
But the wicked will perish: Though the Lord’s enemies are like the flowers of the field, they will be consumed, they will go up in smoke. (Psalm 37:20 NIV)
In your other question about hell, Would Jesus weep for the souls in Hell? I noticed the following. You quote a girl who claims to have visited hell as saying that Jesus said to her:
because of sin and the lack of repentance, humanity ends here, and there are more that perish than those who reach My glory
Notice how even in the traditional Platonic paradigm the scriptural word "perish" (which means to cease to exist) is used, but what they're talking about isn't perishing, its continuing to be tormented forever and ever. The fact that "perish" is used is a clear demonstration that eternal conscious torment is not the original doctrine. If it were the original doctrine then "torment" would be the word used in scripture and would have become the word traditionally used to describe the fate of the lost, but since "perish" persists as the word of choice, being the scriptural word, we know that the present traditional doctrine arose after the New Testament was written, and after this language of "perish" was already so well established that it could not be replaced. The same argument applies to the word "destroy" in Matthew 10:28.
