So, then, if we measure backward down the "First Ascending Passage" to its junction with the "Entrance Passage," we shall have a fixed date to mark upon the downward passage. This measure is 1542 inches, and indicates the year B.C. 1542, as the date at that point. Then measuring down the "Entrance Passage" from that point, to find the distance to the entrance of the "Pit," representing the great trouble and destruction with which this age is to close, when evil will be overthrown from power, we find it to be 3457 inches, symbolizing 3457 years from the above date, B.C. 1542. This calculation shows A.D. 1915 as marking the beginning of the period of trouble; for 1542 years B.C. plus 1915 years A.D. equals 3457 years.Thus the Pyramid witnesses that the close of 1914 will be the beginning of the time of trouble such as was not since there was a nation -- no, nor ever shall be afterward. And thus it will be noted that this "Witness" fully corroborates the Bible testimony on this subject.
I say, let's go to the original "Faithful and Discreet" slave and "Prophet" himself to find how the pivotal year of 1914 A.D. came to be calculated. The reader is then able to draw his own conclusion as to the validity of the WTBTS and its "end time prophecy."
It only seems appropriate then, that the WTBTS's Queens, N.Y. Assembly Hall and the grave of Charles Taze Russell in Pennsylvania are adorned with images and monuments to the WT God.
