There is no doubt that demons are active in human affairs.
I am reading an interesting book by Fathe Gabriel Amorth who was the chief exorcist for Rome. It is available on Amazon :
“Än Exorcist tells his story”
Thanks. I will check it out. This world is a battlefield and boot camp for souls. The only reason anyone could not see that is because of the veils of darkness that those demons hold over peoples minds through their unforgiving judgments.
