"And you will hear of wars and rumors of wars. See that you are not troubled; for all these things must come to pass, but the end is not yet. For nation will rise against nation, and kingdom against kingdom." (Matthew 24:6-7)
The wording implies an expected increase in conflicts due to the stresses of the time leading up to the end. In other words, amplified contention is a precursor of the end time.
A primary means of repression throughout history has been economic in nature. If a person or a group can be kept at the subsistence level—that is, financially able to afford only the bare necessities of life—he or it can be controlled. For instance, a man who must work from sunup to sundown to make enough to feed himself and his family does not have time to further his education, start a business, travel to see how others live, or collude with neighbors to rebel against his rulers. Essentially, such a person is a slave, a serf, a pauper, and those in authority have little trouble holding his nose to the grindstone day after day after day. Either he plods on, or he and his dependents starve.
Westerners usually think of famine in terms of mass starvation in remote, Third World countries. In our mind's eye, we see stick-thin, little children with distended bellies and bones clearly visible under their skin, flies buzzing around their gaunt, staring faces. We imagine interminable lines of such people, bowl or cup in hand, waiting to receive their daily ration of grain or milk. Others we envision lying in the dirt without the strength even to walk.
But there is another kind of famine, not as severe but ultimately just as calamitous. It is the famine of protracted undernourishment, one that weakens the body, making it sickly and short-lived, and crushes the spirit, causing hopelessness and apathy.
This famine will not be just physical but spiritual, as well. So make sure what you believe in is not built on sand, that the roots hold.
