7Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it(Ecclesiastes 12:7).
There are no ghosts,because all spirits go back to God who gave them,so they are not roaming around,which our soul is what lasts forever.
If you are with Jesus,no demon or devil can mess with you.
If you want to go to a haunted house to see if there are demons or devils there,why would you do that if you are with Jesus,and why would demons and devils be hanging around a house for,to get a cut of the money that people pay to enter the haunted house.
There are no ghosts roaming around on this earth.
15And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye? 16And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded(Acts 19:15-16).
If someone did go to a haunted house,thinking it was haunted by deceased humans,ghosts,and then came to find out is was really demons in that house,they better not be a hypocrite,and they better have the authority of Jesus in their life,or else they might find themselves running out of that house naked and wounded,after the demon whips their butt.
