The prophetic revelations, according to Johnston, were eventually fulfilled when the Berlin Wall fell on November 9, 1989, and the disintegration of the Soviet Union occurred on December 31, 1991, eight and 10 years respectively after he received the revelations.
Johnston also claimed that he received a revelation in 1981 that Russia would rise again after the fall of the Soviet Union and that the re-emergence of Russian power would be followed by the death of Fidel Castro.
He then recorded the most chilling part of his prophecies, which are now causing a stir in conspiracy theory blog circles.
Johnston predicted that the death of Fidel Castro will be followed by the complete collapse of the U.S. economy.
According to Johnston, God revealed the following to him.
"When you see that the Berlin wall comes down and when you see the Soviet Union take a severe blow then it makes a recovery, and then you see the death of Fidel Castro; then shall come the collapse of the economic system of the United States."
Other revelations he claimed he received in the 1990s included a devastating Russian nuclear strike against New York and Chinese invasion of the U.S. West Coast.
According to believers, the fact that Johnston predicted correctly that the fall of the Berlin Wall would be the first in a chain of events that would lead to the disintegration of the Soviet Union and the subsequent re-emergence of Russia under Putin raises the alarming possibility that the rest of the prophecies, including the prediction of the collapse of the U.S. economy, will be fulfilled.
Believers argued that when Johnston received the alleged prophetic revelations in 1981 -- that the Berlin Wall would fall and the Soviet Union collapse -- the USSR was still very strong and stable and political analysts had not anticipated the earth-shaking events that occurred between 1989 and 1991.
The apparent accuracy of Johnston's prediction of the collapse of the Soviet Union after the fall of the Berlin Wall drew attention to his prophecies, believers claimed. Even more people began paying attention to his blog after Russia re-emerged as a significant player in global politics under Putin following the annexation of Crimea in March 2014 and the crisis in Eastern Ukraine.
Johnston's prediction that Russia will make a recovery after the fall of the Soviet Union has been fulfilled under the presidency of Vladimir Putin, according to believers. Russia under Putin has successfully challenged the West in Eastern Europe and the Middle East, believers point out.
The recent fulfillment of the prophecy that Fidel Castro would die after the re-emergence of Russian power forces the world to pay attention to the last chilling part of Johnston's prophecy, believers claim.
"As you know Fidel Castro is now a very old man in his 80's and his health is not well," Johnston had written in a post to his blog.
"Cuba could very soon see the death of its long time Dictator," he concluded.
With Castro's death on Friday, November 25, 2016, Johnston's followers are anticipating the fulfillment of the last part of his prophecies, which is the predicted complete economic collapse of the United States.
Conspiracy theorists, especially supporters of the U.S. President-elect Donald Trump, have expressed concern on multiple forums that Johnston's prophecy could mean that disaster would befall the U.S. economy under President Trump.
"I believe Castro's death indicates we have entered the danger zone when our economic system will collapse," writes believer James Bailey on Z3News.com, a Christian website.
"As the world's largest economy, a collapse here would bring a global economic collapse," Bailey continues. "Even without this prophetic sign, there is growing evidence of great trouble in our financial system. Our federal government has now accumulated an unprecedented $20 trillion in debt and it is growing faster than ever before. Our system has been on life support since the 2008 collapse of the housing market, surviving only because of massive infusions of capital from the Federal Reserve Bank. However, their ability to continue producing dollars out of thin air can only continue as long as other nations are willing to continue using U.S. dollars are their reserve currency for International trade, but that support is waning, especially in major emerging markets like Brazil, Russia, India, China, and South Africa."
