Servant of Corrupt gods/Dr Pat Holliday/Dr Sabrina Sessions/Marshall Perot

Can an entire population of a nation become demonically possessed?  Maybe we should rephrase this question:  Can an entire population of unsaved people become demonically possessed?

Occultist, Ruth Montgomery coined the term “Walk Ins”. These explanations were given to her by her spiritual demonic guides [Demonic spirits]. “All believers in the New Age believe in reincarnation, defined as the belief that "we do not really die"; rather, our souls supposedly leave our dead bodies and go into a supernatural state whereby they wait for the next incarnation cycle. Some occultists believe that each soul can choose the time of their next incarnation into a human body at birth, while others believe there is a set cycle by which reincarnation occurs.”  

 ”Walk-ins are defined as "souls who have earned the right, through many lifetimes of spiritual growth, to return directly to the earth plane as adults" (Montgomery, [New Age Writer] "Herald of a New Age", page 202). 3 In other words, these souls in the reincarnation holding cycle want to return to earth in an adult body, rather than incarnating in the body of a baby. Montgomery's Guides reveal that these souls are "not yet perfected souls, but are high-minded beings intent on aiding their fellow humans, and tens of thousands of them are already here..."
