I would say the world is losing faith so something like a spiritual possession sounds Cooky to most . But if we believe the gospel we have to acknowledge evil
Sprits influence metal behavior I think of one violent and crazy man who nominee could approach
was possessed with many a legion of demons afterwards when Jesus drove them out , the man had returned to his right mind and wanted to go with Jesus
“And when he was come out of the ship, immediately there met him out of the tombs a man with an unclean spirit, Who had his dwelling among the tombs; and no man could bind him, no, not with chains: Because that he had been often bound with fetters and chains, and the chains had been plucked asunder by him, and the fetters broken in pieces: neither could any man tame him.
And always, night and day, he was in the mountains, and in the tombs, crying, and cutting himself with stones.
But when he saw Jesus afar off, he ran and worshipped him, And cried with a loud voice, and said, What have I to do with thee, Jesus, thou Son of the most high God? I adjure thee by God, that thou torment me not. For he said unto him, Come out of the man, thou unclean spirit.
And he asked him, What is thy name? And he answered, saying, My name is Legion: for we are many. And he besought him much that he would not send them away out of the country.
And they come to Jesus, and see him that was possessed with the devil, and had the legion, sitting, and clothed, and in his right mind: and they were afraid.
And when he was come into the ship, he that had been possessed with the devil prayed him that he might be with him.”
Mark 5:2-10, 15, 18 KJV
seems as if there is definitely a connection to behavior and spirit it seems wonderful that this man who everyone had given up on so as to chain him and keep Him away found Jesus even in his torment Jesus is really wonderful
