This PDF was available; however, I find it far from satisfying as it fails to mention the Second Civil War in America and the attack from the outside. Hence, it is incomplete.

Furthermore, I disagree with the assumption inherent in the title of “End Time Prophecies” as it is merely the end of an Earth Age and contains perhaps one or two “days of the Lord” out of a possible six different ‘days of the Lord’ that I detect throughout the Bible.

Nevertheless, here it is in English. [25 Dec 2022]
