Hi everyone. Recently I heard a discussion on ghosts and demons which is something I had not thought about too much in the past. I had always thought that demons were not visible and yet heard some say that what people see as ghosts are visible demons. Also that what some see as aliens are demons also. I read in the New Testament where Jesus convinces those who saw Him after the crucifixion that he was not a spirit, or as some may say today a ghost. So my questions are, can demons appear visually? Why if they appear to fool people into thinking the dead can appear as ghosts, don't they appear when requested by mediums who claim to be in contact with them? If they can appear when they want, then wouldn't them appearing on cue give greater power to their lies? As I see it, all who are asked to conjure them today fail (unlike that in 1 Samuel 28) so was it that in those days it was different? That they appeared back then but don't have the power to now?
