Whilst watching TV with a couple I knew, I had a night vision. To my surprise, there were three other spirit beings with me in the living room.

When I confronted them, they introduced themselves to me as the spirits of divorce. They had been inhabiting that apartment for many years, and had caused any married couple that had ever occupied that apartment to divorce.

I drove them away in the name of Jesus. Later, when I interviewed the couple, they told me their marriage was on the verge of collapse. I told them the reason;
They were living with an enemy.

Someone once told me how he developed diabetes. He purchased a home which used to be a hospice. Shortly after moving in, one night, he was asleep when he saw a dark shadowy figure walking towards him. The shadowy figure entered him and soon after that, he developed diabetes.

The traditional Christian view of demons is that they are disembodied spirits that afflict or possess people. The activity of demons however transcends this. Demons can also inhabit buildings, lands or spaces. Ignorance in this area has led to the unrestrained activity of demons in homes etc.

They may be already inside.
