If a person is possessed by a demon. What exactly should be done.

Should we cast the demon out/ negotiate with the demon to leave the person/ allow the demon remain there/ flog the demon out/ disgrace the person publicly and watch the demon go/ make sacrifices to god or maybe dialogue.

Have we actually consider if the person wants to be delivered,or if the demon actually wants to leave the person. Or if the demon is for good or for bad. Also what gives us the impression that a person is possessed? Did we see it through a microscope or did we hear a voice from heaven telling us that a person is possessed. Also why can't we just leave it to God to handle. why do it our self.

if you see such a person, you either have him checked by a psychiatrist or have yourself checked by a psychiatrist.

Logic Mind: have yourself checked by a psychiatrist.

OP, try this.

God created Lucifer and all the demons, so those demons are the work of God, you should thank those demons that have come to bless in the name of God.
Everything God created is good ... you do not eject the creation of God ....
Finally, avoid calling a pastor, it will not remove any demon, and instead, end up financially abusing you.

Am just concern if God actually gave us the power 2 cast out demons and if demons realy need casting out.

Demos are spirits who have lost thier bodies thats why they desperstely look for human bodies to dwell. They dont belong to this plain .they Should be CAST OUT!
