Hell is the separation of a human soul from GOD. The reason he is so separated is because that soul never knew GOD. The reason there is anguish in hell is because come Judgment Day, every soul will get a glimpse of GOD 's glory. If not found in the LAMB's BOOK of LIFE, that soul will be turned away from GOD's glory.
The fact that a person ends up in hell has nothing to do with GOD sending him there. That person in life made choices that led him/her to be in hell.
The people that are in heaven are there because they wanted to be one of GOD's children and were willing to set their desires aside to allow GOD to motivate them as HE saw fit at some point in their lives.
The awful thing is that anyone would be so stuck on their own plans, desires, their own ways, that they made no place for GOD and what he or she ends up with is the hell he or she fabricated for his or herself ------ totally apart from GOD.
Since Jesus was in hell (Acts 2:27,31) before God resurrected him, could it be said Jesus never knew God?
Did Jesus believe there was anguish in hell? Jesus likened being dead to being in a deep sleep according to John 11:11-14.
Didn't Jesus know the already written Hebrew OT Scriptures ? Jesus would have known what Solomon wrote at Ecc. (9:5,10) that the living know that they will die, but the dead know nothing.....
Jesus would have also been familiar with the Psalms. Such as Psalm (6:5) that in death there is no remembrance; (13:3) talks of sleeping the sleep of death; (115:17) the dead do not praise God; (146:4) at death thoughts perish.
Jesus would have also known Ezekiel (18:4,20) that the soul that sins dies.
Jesus even cautioned at Matthew (10:28) to be in fear of the One that can kill the soul.
What about Adam? Where is Adam today? Genesis (2:7) plainly states that Adam, after receiving the breath of life, that Adam became a living soul.
No where does it say Adam came to have a soul, or that Adam came to possess a soul, but rather Adam was a soul. Adam was from dust and at death Adam returned to dust.
Daniel wrote (12:2) that those that sleep in the dust will awaken.
With the exception of those of Matthew (12:32) and Hebrews (6:4-6) because they are not considered in hell but in Gehenna. (Gehenna symbolic of destruction). The majority of mankind will awaken from death on resurrection morning or the thousand-year reign of Christ. (Matthew 20:28)
At that time all in hell will be delivered up according to Rev 20:13,14.
Then emptied-out hell and death die a symbolic second death or dying out of existence forever. Isn't that why Revelation (21:4) could say that even death will be no more?
