Thanks for the good replies,
Scooter.
I also found this interesting passage -
Matthew 25:31-33, 41-43, 47
31“When the Son of Man comes in his glory, and all the angels with him, he will sit on his glorious throne. 32 All the nations will be gathered before him, and he will separate the people one from another as a shepherd separates the sheep from the goats. 33 He will put the sheep on his right and the goats on his left.
41“Then he will say to those on his left,
‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels.
46
“Then they will go away to eternal punishment, but the righteous to eternal life.”
The one passage that casts doubt in me still is Matthew 10:28. It seems to say that the soul can be "destroyed" in Hell.
28 Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell.
