That verse, which comes from Revelation 6 is a description of the famine which comes early in the Tribulation. According to the NIV study Bible, we read:
"Wheat...barley. One quart of wheat would be enough for only one person. Three quarts of the less nutritious barley would be barely enough for a small family. Famine had inflated prices to at least ten times their normal level."
According to Jesus: "There will be famines and earthquakes in various places" (Matthew 24:7)
"There will be great earthquakes, famines and pestilences in various places, and fearful events and great signs from heaven" (Luke 21:11)
This leads to yet another article predicting this scenario:
Food prices rocket by 50% as global hunger epidemic causes riots and famines
The increase will be triggered by the exploding world population, rising cost of fuel and increased competition for water, according to a leading Government think-tank.
Spiralling food prices will push hundreds of millions of people into hunger, trigger mass migration and spark civil unrest, the report warned.
Global food prices are already at a record high. Last month the price of cereals, sugar and meat soared on the world’s markets after a series of crop failures caused by bad weather.
At the same time, climate change will increase the risk of droughts, floods and crop failures – creating a ‘perfect storm’ of food shortages and above-inflation rises in prices.
Professor John Beddington, the Government’s chief scientific adviser, said the food system was failing.
‘Firstly it is unsustainable, with resources being used faster than they can be naturally replenished,’ he said.
‘Secondly a billion people are going hungry with another billion people suffering from “hidden hunger”, whilst a billion people are over-consuming.’
Worsening famine will be coming on the earth, exactly as predicted by biblical prophecy. Just like the other signs, this one too is marching along - right into the Tribulation.
