Punishment and death is eternal, just as the life everlasting is eternal....
to deny that is to deny the Bible.
Hell is nothing more than a Norse myth. Google it.
I went to a very conservative Seminary and it was acknowledged by the professors quite reticently that probably around 60 percent if not higher of Protestant pastors are in fact universalist in their private beliefs. Universalism is the belief that an omnipotent and loving God would not send anyone to an eternal Hell and thus all will arrive at Heaven. I’m sure there are some variants but that is the gist of it.
Even someone like William Barclay admitted to this belief in his autobiography - he’s not the best example. Rob Bell along with all the guys in the emergent church/ social justice persuasion are not surprisingly falling into this heterodox belief system.
