>Some are irredeemable though
Nonsense.
There are three heavens mentioned in the bible. The first heaven and hell are here on earth.
Who rules hell? Who rules earth?
Go tell these kids they're not in hell.
Putting down the "holy books" is the last thing people should do. Opening their minds when they read them is what they need to do. Read from a position of looking for truth in the message, rather than reading from the position of authority of the book.
There's very valuable information in the scriptures, and not just the bible. Look past the words and see the Word (Truth) so to speak.
