Do you know how demons mess with people, forlorn? Its not all lamps flying through the air, and menecing laughter, or shadows creeping around(though that stuff can happen)
NO, its horrible sins you will start to fall into. Its chaos insuing in your house. People suddenly getting horrible angry, when before they never did. Abuse. Horrible nightmares. Depression. etc... I really would get rid of that book, and anythign else like it. But i cant force you. Just Seek Jesus with all you are. Truly He loves you, but he cant help you adn guide you, if you arent born-again, adn livnign for him, in order for him to keep you safe. SIgh...anyway...Your in my prayers my friend.
