I can't speak in depth about science or religion, but I can relay personal experiences. I know for most this won't mean a thing, but for others it might so I'll share. As a christian, I've been attacked in the spirit many times. For example, I have awaken in the middle of the night from a state of lucid dreaming and realize that demonic forces are present there with me in my bedroom and I'm literally paralyzed with fear and have a hard time breathing. My wife is sound asleep next to me unaware of what's happening to me, but I can't move and often times it feels as though an evil shroud is somehow blanketing me...it's terrifying. In the darkness I see nothing and I hear nothing, but in the spirit I know with complete certainty that I'm being attacked....evil is around me and it hates me and what I believe. When it first happened to me years ago I didn't know what to do or what to make of it, but I learned how to combat it. Now, I use "combat it" rather loosely as me personally....well....I'm powerless to do anything. In the occassions this happens to me I call out the name of Jesus very softly and the holy spirit washes over me like a flood from head to toe and every sense of evil vanishes in that instant. I pray for God's angels to surround me and my family and protect us and again the holy spirit washes over me and my entire body literally tingles from head to toe in a second. This isn't a psychotic episode. This isn't a state of delusion. This isn't a narcotic induced scenario. These are the demonic forces of evil that attack Christians especially those both newly saved and those with renewed convictions. Satan and his minions will do all they can to place us in a state of complete unrest, anxiety, doubt and fear. Fortunately, all that is needed is the name of Jesus spoken aloud or in silent prayer and in that instant the evil vanishes in fear. See, Jesus has already won the battle..the outcome has been determined and the enemy knows this and are trying to take as many victims down with them as they can before they are beaten forever; still, tormenting believers in the interim seems to be something they enjoy. Regardless, that's the power the name of our Lord commands and it's the best example of something physical or tangible I can illustrate. As has been said on many occassions, Satan's greatest victory is convincing man that God (and Satan) do not exist. Yes, they're very real, they're very powerful, but the world dismisses both because they are blinded to the reality of their existence....this thread is absolute proof of that.
