New Defender's Study Bible Notes
28:7 familiar spirit. Communication with spirits is evidently as old as history, but has been strictly forbidden by God (Deuteronomy 18:9-14). The entities called forth by spirit mediums (a process called “channeling” in the New Age movement) are not the spirits of deceased human beings, as often claimed, but are evil spirits, or demons, under the direction of Satan. When a spirit controls the body of a medium, essentially the body is demon possessed. Any “guidance” from such a source will inevitably be deceptive and dangerous, leading the one so deceived still further from the Lord.
