Are ghosts real?
Yes they are! But what are they? Satan is the devil. He was cast out of heaven for Jesus said, ‘I beheld Satan as lightning fall from Satan.’ Luke 10:18. And Satan did not come alone. ‘And the great dragon was cast out, that old serpent, called the devil and Satan which deceiveth the whole world: he was cast into the world and his angels were cast out with him.’ Revelation 12:9.
These are what we know as ghosts. Like their leader they work to deceive us into contradicting the Bible, the Word of God. The devil is the enemy of God. The deceive by pretending to be those we loved before they died. The spirits through human mediums tell us things that were personal to someone and could convince us so easily. Do not dabble in anything like that. It is of evil.
