Why would religion embrace the sick concept of hell; because they are convinced that God wants that.
Why would a Great Loving merciful God, want eternal pain for anyone? That is a great contridiction, but certain scriptures seem to imply it. Thats WHY certain believers, then believe it.
And I want to examine that contridiction in detail.
Peace.
Why? because the clergy teach the flock.
But according to Acts [20vs29,30] the clergy dress in sheep's clothing in order to fleece the flock. Often the clergy have a political agenda instead of Christ's.
In scripture 'fire' can be figurative of destruction.
Gehenna was a garbage dump where things were destroyed and not kept burning forever. So Gehenna [hellfire] is a fitting symbol of destruction and why Psalm 92v7 mentions destruction or annihilation forever.
2nd Thess1v9 mentions punished, not with fire, but everlasting destruction.
God want all to repent [2Peter 3v9b] so as not to perish or be destroyed.
As far as 'eternal hell' please notice Rev 20vs13,14 because once all in hell are delivered up [resurrected] then 'emptied-out hell' dies a symbolic second death of no return.
