So maybe you would 'qualify' hell before assuming what Jesus believed.
Right. We should all qualify before assuming......
Jesus at John 11v11 said his friend was asleep.
When the disciples thought Jesus was talking about usual sleep they told Jesus in verse 12 that if he is asleep he would do well. However, in verse 13 Jesus spoke of his friend's death. So by verse 14 Jesus makes it plain that his friend's sleep was death. -John 5vs28,29.
At first glance Jesus words at Matt [25vs41,46] seem to promote a literal fire.
Jesus never contradicted God's Word which at Ecclesiastes 9v5 says the dead know nothing.
At Mark [9v47,48] the original Greek word translated 'hell' is Geenna.
This word comes from the Hebrew Geh Hinnon meaning Valley of Hinnom.
This Valley was outside of Jerusalem and in Jeremiah's day it was called the 'valley of slaughter' where carcases lie unburied. [Jer 7vs30-34]
So the valley of Hinnon would become, Not a place of torture, but disposal of dead bodies. By the time of Jesus day this valley [Gehenna] was a garbage dump where fire destroyed refuse and carcasses. So Jesus could easily use this valley of Hinnon or Gehenna [hellfire] as a fitting symbol of destruction not torture. Jesus further drives home his point at Matt 10v28 warning God can destroy both body and soul. The soul that sins dies.- Ezekiel 18vs4,20.
Under the Mosaic law justice was that the punishment must fit the crime.
Eye for eye, tooth for tooth, life for life...... Punishment was not to be greater than the crime. What crime fits burning forever?
Since literal fire can not burn spirit creatures such as Satan then Jesus words at Matt [25v41] were speaking symbolically just as Jesus was speaking about people not being literal sheep or goats in verse 32. This is in harmony with Psalm [92v7] speaking of the destruction or annihilation of the wicked and not burning them forever.
Sin does not go unpunished. That is why Romans [6v23] says the price tag [or punishment] of sin is: death. 'Death' according to Romans [6v7] is that one's death frees or acquits a person from sin. So 'death'
stamps the price tag of sin as "Paid in Full". This does not mean innocent but like a governor can pardon a person so the charges no longer stick. Jesus death pardons excluding ones like those Hebrews 10v26.
The punishment of Matt [25v46] from the Greek word kolasin is used in connection to cutting off or pruning as with tree branches.
So the everlasting punishment then would be forever cut off from life.
Or as 2nd Thess. [1v9] says punished with everlasting destruction.
That is why mortal Satan according to Hebrews [2v14 B] does not burn forever but Satan is destroyed by Jesus. Jesus proved to be the 'seed' of Gen [3v15] that deals Satan [serpent] a fatal death bruise to his head.
Since God takes No pleasure in the death of someone wicked according to Ezekiel [18v23]; 2nd Peter [3v9] , then how could God delight in burning someone for all eternity? Psalm [145v9] says God is good to all.... that is why God desires all to repent rather then 'perish' or be 'destroyed'.
Jesus did not go to Gehenna. Gehenna the place of no resurrection but destruction.
Rather as Peter said Jesus was not left in hell [ haides] - Acts 2vs27,31,32]
which is in harmony with the rest of Scripture.
The Psalms say of the dead that the dead sleep.
Such as:
6v5 that there is no remembrance of God in the grave.
13v3 sleeping the sleep of death
115v17 the dead do not praise God....
146v4 at death thoughts perish.
In connection to the resurrection [Acts 24v15], except for those destroyed of Matthew 12v32; Hebrew 6vs4-6; 10v26, death and hell 'delivered up' the dead according to Rev [20v13,14]. Emptying out hell will mean restoring life to the dead during Jesus 1000-year reign over earth. Then vacant, emptied-out hell, void of people, dies a symbolic second death of never returning and even death will be no more- Rev [21v4]. Our last enemy 'death' [1 Cor 15v26] is destroyed forever. 'Death' swallowed up forever as Isaiah [25v8] says.
So Just as Martha believed at John [11v24] there will be a resurrection on the last day, or Jesus peaceful millennial-long day of ruling over earth, when as the prophet Daniel looked forward [12vs2,13] that the worthy dead will awaken from death's sleep on resurrection morning, so to speak, from the dust of the ground to everlasting life.
