Disarming the Spirits

It happened in Nepal when a new missionary to the area went into a darkened local spirit house and saw a man chanting while hovering and spinning in the air at the same time. When the missionary entered, the shaman, who was hovering in the air while spinning and chanting, spoke authoritatively and told all those present that this one was a messenger of the Christian God and warned the missionary to go. The inference being that the shaman had ultimate power and the missionary should leave. The new missionary wisely interpreted this as a power encounter over who had the right to be called the Most High God. He then spoke out in a voice that all could hear and in Jesus Name he “disarmed or came against the power that held the shaman up” whereupon the shaman crashed to the ground. Now who is in control?
