The words “spirit” and “ghost” are really the same word in the
Bible. We see this in the way we describe the Holy Spirit as the Holy Ghost.
But the folklore of ghosts comes from legend and myth.
We believe ghosts are spirits that return to earth to communicate,
haunt, get revenge, whatever it is ghosts want to do. That is not the case.
When we die, our spirits depart from our body and wait in a place
called “the grave” or “Hades” until Christ determines the time to return to
Earth and reunite our spirits with a resurrected body, which is spiritual,
physical and super-natural.
So will it be with the resurrection of the dead. The body that is sown is perishable, it is raised imperishable; it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; it is sown a natural body, it is raised a spiritual body. 1 Corinthians 15:42-44
So during that time after we die to the time Christ returns, we
are in a spiritual state. Call it a ghost if you want, but you won’t be Casper
the friendly kind.
When God allowed the witch of Endor to call up the spirit of
Samuel the prophet for King Saul, this is how it was described:
The woman said, “I see a spirit coming up out of the ground.”
“What does he look like?” he asked.
“An old man wearing a robe is coming up,” she said.
Then Saul knew it was Samuel, and he bowed down and prostrated himself with his face to the ground. 1 Samuel 28:13-14
This was a one-time experience in the Bible, not a common
thing. Spirits didn’t routinely come
from the dead. God allowed this to
happen for Saul to see what he was messing with.
But notice, Samuel’s spirit was recognizable and had personality. It was a spirit and it was a person.
So yes, we will be a ghost/spirit for a time, then we will be in
physical/resurrected state.
However, you won’t be roaming around the earth scaring your
friends, but content in the presence of God.
