Saying that a Loving and Just God will tortue billions, and that FOREVER, has been taught in nearly EVERY religion in the world in various forms! CHURCHianity adds worms given eternal life to gnaw on them!
This is COMPLETELY alien to the Bible, which uses fire as a Symbol of destruction , since that was it's main use (othere than cooking & warmth) in those ancient times!
A Baptist 'minister' once said God taught it to "scare people to Heaven"!
That was a HALF truth; God never taught it, but MAN does- to scare people to their CHURCH! (Money, money, money!)
