Don't know. When was it published? That statement is true however. I know people born then who are alive today, and the age of Satan's rule will end very shortly according to the things that Jesus said to watch for, and according to Revelation to John. What was the publication date?
I assume that you are falsely claiming that statement to be a prophecy. No, it's stating the understanding of the scriptures. It is God Himself who makies prophecies, through various people. He no longer does that, and hasn't since the last of the apostles died.
