IS HELL BEARABLE?
It has been recorded as matter of illustration, encounters with people in the afterlife. Examples of Lazarus and the Rich Man (Luke 16:19-31), or the angels condemned already (Luke 8:26-33) but that refuse to stay in their place of punishment.
In both cases, the conversation seems intelligent to a high degree, even in the case of humans, like the Rich Man or prophet Samuel at Endor (1Samuel 28:8-25), which makes you think if the spirits of the condemned, are really in a place of torment.
From all stories told to us in the NT, we can gather two places, as it says Luke 16. A place of punishment and a place of reward. However, these places are not what we understand as Hell or Heaven as such.
The answer is that Hell, as the ultimate place of punishment, does not exits yet, therefore, the people who lie in it at the moment, do not experience the fulness of their punishment which will be accomplished only after the Great White Throne of Judgement, in the last Day (Revelation 20:11-15).
This ability of more or less being in control of our situation, is also a direct product of that condition. Condemned people are not in a place of torment where they will be punished according to their own sinfulness, but in a lesser state of suffering, that ends up being bearable somehow until the Day of Judgement.
On the other hand, since demons still have a role to fulfil on Earth until all creation is accomplished, they can also opt for leaving out of their cells in darkness, and step into creation in order to increase their condemnation by promoting others into disobedience to God Almighty
(Job 1:6-12; 2Peter 2:4; Jude 1:6).
Both ways are only an ante-Sala of what is to come eventually.
Only in Eternal Punishment, all altercation between humans and demonic entities, will be out of the question because it will be unbearable to them.
Only in Eternal Bliss, will be the righteous saved, and connect directly with God and each other, as God wants us to be.
