The Guatemalan poor have no land, so they gather a mob and all move in at once onto unoccupied land. These squatters are called “invaders,” and their removal from private property frequently leads to blood-shedding. They cling desperately to a place they wish to call home without having any right to be there.
This is a Biblical comparison, not a political commentary. Demons are invaders. They have no right, but they simply move in, through sin, and occupy the human heart and mind. They must be opposed and evicted with force. They cling desperately to the spot they have laid claim to.
When you pray, it is no grandmotherly knitting. It is doing violence to the kingdom of Hell. It is demanding they obey the rightful law of God, forcing them to submit to God’s superiority. And from the days of John the Baptist until now the kingdom of heaven suffereth violence, and the violent take it by force. — Matt. 11:12 KJV.
