History is not endless.
"He is the first" so he is beginning of the history and "He is the last" so he is at the end of history.
If he is the beginning and he is at the end then he will connect them both. So there is a nexus connection between the beginning and the end.
The first page of history is connected with the end of history. To understand how history will end? first, we have to also study the beginning of history.
In order to study the world today and penetrate its reality (political reality, economic reality, monetary reality, and military reality) you have to see the world with your internal eye, not external observation.
