When I was a 19-20 years old still considered youth at church....
One of the Girls is church that was H.G. filled: she would shout dance and pray in tongues all the time.
Then one day at her house her family and I was setting around the dinning room table, her mother asked "what's was wrong"?, then mother said "something inside you is getting made ain't it?"
The girl said "yes, mom you are scaring me."
So mom said "let's pray." We prayed and the girl "Roberta" took off shouting like she always had and went into the living room.
I walked in there to and watched as her mom was rebuking a spirit out.
Roberta was freaky looking at this time, and in a growling voice said, "You can't have her, she's mine." and the I heard speak in a wicked sounding dialect of tongues.
I then called the Pastor to get over here.
Pastor showed up, looked at Roberta sitting in a chair, studied her and said, "Roberta", and she was back to normal.
And the he prayed with her back thought to the H.G.
I was very confused.
I asked my pastor how can this happen to a H.G. filled Christian?
He told me that Roberta had a lot of confusion in her life.
I did not know it but she had a weakness and sin in her life.
My Pastor said the devil used this confusion as an open door.
