It was foretold here:
What is taking place today throughout the world economy is a clear, advance warning signal that we are nearing the end of the present economic systems on earth. While temporary measures by some governments may halt, or even reverse, the trend for a short while, these will do no good in the long run. Why not? Because present world conditions, including the economic uncertainties, provide unmistakable evidence that the entire world system, not just the financial part of it, has entered its time of the end. ...
... The "last days" were foretold to culminate in a "great tribulation such as has not occurred since the world's beginning until now, no, nor will occur again." (Matt. 24:21) That tribulation will clear the earth of the economic factors that have brought and continue to bring hardships upon millions. In fact, all human governments and their monetary systems will be replaced by one government-a righteous administration in the hands of the self-sacrificing Son of God, Jesus Christ.-Isa. 9:6, 7; Dan. 2:44.
When the "great tribulation" strikes, even the most stable of the world's monetary systems will be unable to buy protection. The situation will then parallel that of the inhabitants of Judah and Jerusalem in the seventh century B.C.E. Regarding them, the prophet Ezekiel foretold:
"Into the streets they will throw their very silver, and an abhorrent thing their own gold will become. Neither their silver nor their gold will be able to deliver them in the day of Jehovah's fury."-Ezek. 7:19.
So the danger in which we find ourselves today is far graver than the collapse of all national currencies. Bible prophecy clearly establishes that the generation now living faces an unequaled "great tribulation," at which time only an approved standing with God will be of any real value. (Matt. 24:34) People everywhere should therefore think seriously about what they can do to survive that destruction. Are you endeavoring to build up a record of fine works with the Creator so that you may be among those hidden in the day of his fury?
