The Bible makes several references to the method used by the powerful global merchants (bankers/traders) of the Earth. It reveals what method they will use to deceive all of the people of the Earth.
"...For your merchants were the great men of the earth, for by your sorcery all the nations were deceived."
—Revelation 18:23
The word sorcery is the Greek word "pharmakeia" which translates to our modern word pharmacology.
But the practice of pharmacology does not only include putting pharmaceuticals into your body, it also includes putting anything unnatural into your body. This being the case, the Bible would consider amalgam ("silver") dental fillings and vaccines "pharmakeia" as well.
Moreover, the inhalation of foreign substances would also fall under the category of "pharmakeia". This being the case, inhaling aluminum, barium, mercury, and other unnatural substances found in chemtrails would also be considered "pharmakeia".
Is it possible that the spraying of chemtrails all over the world is one of the methods used to dumb people down so they are more easily deceived into accepting the corruption of the final world kingdom ("The New World Order")—The entity some Bible scholars refer to as "The Revived Roman Empire"?
Considering the massive global spraying that is now being witnessed by millions, and considering that mercury (in chemtrails) causes apathy, fatigue, short-term memory issues, and generally makes people unlikely to get involved in solving global issues or to work to rid governments of corruption, the global practice of pharmakeia through chemtrail spraying is a perfect match to this Biblical prophecy.
