Manga, I believe you, because I believe that Christianity's foundation isn't love or worship of God or hope or whatever. The main foundation of Christianity is fear. Without fear, they have nothing. And I know how powerful and gripping fear can be, especially when it seeps in from childhood.
So, if you were to learn that the hell that is mentioned in the Bible isn't the Hell that we have been raised to believe in, would it make a difference to your fear? It made all the difference to me. It started when I read a book called Love Wins, by Rob Bell, a Christian author. I recommend this book to people who are struggling with fear stemming from Christian teachings. (Brainwashing)
The main point is that every single place in the Bible that mentions the word Hell, has been translated from one of 3 different languages: Aramaic, Hebrew and Greek. And the people to whom these passages were written, understood a literal place that these words were talking about. Sheol, Gehenna and Hades. These 3 words have all been translated to the one umbrella word: Hell. But they were never meant to refer to what we think of as Hell today.
So even if you're questioning the Bible, you can be assured that there is no Hell to be afraid of. Put your energy into understanding the original meanings of "hell" and your fear may just dissipate on its own.
As far as the "visions" in the videos, i agree with Velma, BooksCatsEtc, and Pasta Chick.
