“Let's Say 1914 Was The Establishment of God's Kingdom....what is the significance?”
Um, where is it? There would only be a significance if there were any such kingdom to be observed. To quote a line from a famous movie, Jerry Maguire (1996): “Show me the money!”
This “invisible kingdom” is really just another psychological mechanism for control, just like all the other imaginary concepts religion uses, such as hellfire, purgatory, limbo, heaven (sometimes with “72 virgins,” depending on which side of the world you live), Valhalla (Norse mythology), “enlightenment”/Nirvana (Buddhism), etc. It’s always the same thing: something invisible (of course!), or at least only visible to “special” people with “special” glasses or something (think Joseph Smith of the Mormons, native Indians hopping around the campfire strung out on “magic” mushrooms, African “holy men” wildly bouncing around to banging drums bombed out on rum and Coke or whatever in a “spiritual” trance, etc.).
Sigmund Freud could see through the modus operandi of religion as an anthropological/sociological phenomenon. His opinion was that religion was a “neurosis” – a figment of human imagination arising from “repressed feelings of human dependency on a father figure.” Looks like nothing but of sleight of hand there. So, I guess folks who are bend on “seeing” and reporting on the invisible goings-on of the big “upstairs” of the netherworld are just basically kind of, well, nuts – especially when they keep getting things wrong all along!
