They can move through time and space, but cannot be everywhere at one time. They are behind the worst events of history and behind the most evil men. They are able to fool people into believing false religions and into believing that ghosts, poltergeists and other spirit manifestations are 'spirits of the dead' who are benign. All spirit manifestations of this nature are demonic and all of them are evil. They are NOT spirits of the dead.
Demons merely pretend to be departed humans.
They are able to do this because they have observed those who died and can mimic their looks, voices and general personality traits. The word of God, completely and utterly, is perfect and without flaw or contradiction. It is our only guide for living and for faith. Everything we think, say or do, must come from, be based on and return to, this word, which was written by men inspired to do so by the Holy Spirit. We do not, as BTM, accept other versions, which are based on corrupt sources and texts.
