A person is an idiot if he or she believes any bible teachings.
Nothing of the speculation based on any religious doctrine can be proven.
The Watchtower, now called JW Org, stands as a monument to the stupidity of believing interpretations of Bible readings. It has wasted the lives of millions of JWs who hang on every word they have been taught only to be given a new set of false promises each generation.
Had it been true, the promises would have come true and the teachings would never have to change.
Not one of the promises of Jehovah's Witnesses has ever come true because they are not based on evidential truth. The Bible and its contents were selected as propaganda to control the mass of people, particularly in the dying days of the Roman Empire. The poor and uneducated being the most susceptible.
The Bible has always been a propaganda tool, it is not divine, it is not "truth".
Wakey wakey Jehovah's Witnesses!
