Here is another statement by Rutherford about 1925 that I think hasn't been noticed before:
"The old world has ended and is in travail and distress. The greatest crisis of the ages is upon the nations of the earth. Men who think are alive to the fact that the collapse of the old order is at hand . . . . and God's day of judgment has come. Speaking of the day now at hand, Jehovah said through his prophet Joel: "Assemble yourselves, and come, all ye nations, and gather yourselves together round about....Let the nations be awakened, and come up to the valley of Jehoshaphat.... The Lord shall roar out of Zion, and the heavens (ecclesiasticsm) and the earth (organized society) shall shake; but the Lord will be the hope of his people." -- Joel 3:11-16 . . . ."The present order of things cannot survive the conflict for which the nations are preparing and to which they are rapidly rushing, because of the terrible instruments of destruction. W. L. Warden, of the London Mail, says: 'The next war will last but a few days. I mean it literally. And in those few days, with the new air and gas attacks which have been planned by headquarters' staffs, London and Paris will be wiped out in a night.' Jesus described that conflict thus: "Then shall be great tribulation, such as was not since the beginning of the world to this time, nor ever shall be. And except those days should be shortened, there should no flesh be saved.' -- Matthew 24:21, 22.
"The tangible evidence indicates that the great conflict will be within the next two or three years and of short duration. The Scriptures indicate that the trouble will reach a climax in 1925 and quickly burn itself out. The prophets then indicate that those who have faith will cry unto the Lord and He will bring them out of the trouble and into their desired haven of rest. (Psalm 107:25-30) The prophet Haggai states that following this great trouble the desire of the peoples will be realized (Haggai 2:7). That desire is for life, liberty and happiness."
