One time I was trying to pray, and I felt it was not going any higher than the roof. Something was hindering me, terribly. So I asked the Lord what it was that was keeping me from getting thru. Immediately, I saw a dark form in the room. It had no face, and no substance. It was an intensely dark nothingness. But it had the shape of a person.

I was terrified, and asked the Lord why that demon was there. Immediately, I saw a Barbie doll. And I knew.

When I was a little girl, I became very attached to my Barbie dolls. I would make clothes for them, and they were intentionally immodest. I played dating with Ken. I imagined all kinds of impure things with those dolls. From that point, I became obsessed with impurity, in my thought life.

When I became a Christian, I tried to get rid of those thoughts. It was a horrible battle. And I never completely won. Many times, I would slip back into that impure mindset. And I would slide far away from God.

That day, when I saw that demon, I knew that I had a stronghold in my life, that needed to be broken. I had given a place to the devil.

Parents, I implore you: do not allow your little girls to play with Barbies! It can destroy their precious souls!

('I played with Barbies when I was a little girl and I never had the problems you mentioned you had while playing with them.')

I mean that to allow a child to play with a doll that is shaped so as to appeal to a playboy mentality, is just plain wrong. It puts a stumblingblock in the way of that little one. Perhaps not every girl will come under demonic influence thru that doll. But many, many do. I have known some of them. Boys get a great charge out of those sexual dolls. I have also seen little boys get overly attracted to those dolls, and it awakens something in them that is wrong. Should Christians parents take the chance, just to avoid "legalism"?

The Barbie doll was inspired by and modeled after a German prostitute doll named Lilli. That should tell you enough.

If you really want to know more, just Google "Jack Ryan" who was the creator of the Barbie doll, and you will find out more than you would ever want to know about the mentality behind her creation.
