I believed everything.. never questioned any of the beliefs, no matter how odd they were. I even believed that everything and that happened was due to demons.. any odd noise was a demon. I once thought I had a demon attack because I was naughty enough to be reading a Stephen King book at the time ( I threw it out instantly). It turns out I had sleep paralysis.
The other belief that I still try to shake off is life after death/armegeddon. I have a big phobia of death because of the witnesses. I don't know what lies on the other side, and once in awhile I still worry about what happens if armegeddon comes and destroys me forever.
What woke me up was an elderly brother who I used to read the 'proclaimers' book to. He was a devoted brother for decades. Went through the ban on Jehovah's Witnesses in Canada, and one of the nicest, kindest, softest people you will ever meet. When he died, it threw me a curve ball. He spent 8 decades telling people god's kingdom is coming. He believed the end was just around the corner... and he of all people , never got to see that day. That was a " aha" moment and my heart became cold.
