Lots of people were saying they saw my Mother after she died. They thought and still do, that they were bringing me comfort in saying that. Then I had a dream where she came to me and was scolding me for something. I invoked the name of Jesus and rebuked Satan. That was that.
Jesus said that we were not allowed to come back and talk to our loved ones. Even if it’s just to warn them about the reality of HELL.
So God’s not going to allow them to come back and give comforting messages and other BS either. If you see a ghost, know that it’s not a spirit that lost it’s way or hasn’t gone into the light, but something else. And they aren’t friendly. They deceive. And they posess.
Oh they do come back, not everyone can see them, but they do and once you have experienced it you know it.
I’m a little leery of this story too as Jesus mentioned once you die there is no coming back in the story of Lazarus and the Rich Man (Luke 16:19-31)
In the OT/Tanach the story of Saul calling Samuel from the grave through the witch of Endor indicates that the actual Samuel did speak from the other side. But the consorting with familiar spirits (like the way the witch of Endor had her 'craft') is abosultey forbidden.
And we have the witness of Paul and others that Jesus spoke to them personally even after He ascended into Heaven, and He certainly came from the dead to dwell with His deisicples for a perhaps forty days, in and out of their where/when, before He ascended to Heaven.
