The system of this world, in its silent language, goes on teaching us a great lesson. Here, again and again, we see the phenomenon of the darkness of the night coming and enveloping the light of the day. Here, every day, the day dawns and dispels the darkness of the night. By analogy, if a group or community is enjoying pomp and glory, it should not harbour the misunderstanding that its pomp and glory will never come to an end. Similarly, if a group or community is oppressed, it should not think that it will remain oppressed forever. God who, in the realm of the heavens, causes the light to be plunged into darkness, and who then restores it, can certainly cause similar events to occur in the world of human beings also. There is no power that can prevent Him from doing so.
