But that Awake! article clearly states "Does this mean that the above evidence postively points to 1975 as the time for the complete end of this system of things? Since the Bible does not specifically state this, no man can say."
So why write and elude to it, again and again ?
My understanding, is that each time they allued to 1975, they also mentioned and pointed out that it does not necessarily mean the end will come then. It only means that 6,000 years of man's existance on earth will end in 1975. Even after the Freedom Sons book came out, Franz said that no one should be saying anything about 1975. And you were even allow to reject the chronology presented. Note what these WT publications stated: WT - 10/15/66 - "Rejoicing 'Over God's Sons of Liberty' Spiritual Feast"
At the Baltimore assembly Brother Franz in his closing remarks made some interesting comments regarding the year 1975. He began casually by saying, "Just before I got on the platform a young man came to me and said, ?Say, what does this 1975 mean? Does it mean this, that or any other thing??" In part, Brother Franz went on to say: ?You have noticed the chart [on pages 31-35 in the book Life Everlasting?in Freedom of the Sons of God]. It shows that 6,000 years of human experience will end in 1975, about nine years from now. What does that mean? Does it mean that God?s rest day began 4026 B.C.E.? It could have. The Life Everlasting book does not say it did not. The book merely presents the chronology. You can accept it or reject it. If that is the case, what does that mean to us? [He went into some length showing the feasibility of the 4026 B.C.E. date as being the beginning of God?s rest day.]
?What about the year 1975? What is it going to mean, dear friends?? asked Brother Franz. ?Does it mean that Armageddon is going to be finished, with Satan bound, by 1975? It could! It could! All things are possible with God. Does it mean that Babylon the Great is going to go down by 1975? It could. Does it mean that the attack of Gog of Magog is going to be made on Jehovah?s witnesses to wipe them out, then Gog himself will be put out of action? It could. But we are not saying. All things are possible with God. But we are not saying. And don?t any of you be specific in saying anything that is going to happen between now and 1975. But the big point of it all is this, dear friends: Time is short. Time is running out, no question about that.
WT 5/1/68 "Making Wise Use of the Remaining Time":
Does this mean that the year 1975 will bring the battle of Armageddon? No one can say with certainty what any particular year will bring. Jesus said: "Concerning that day or the hour nobody knows." (Mark 13:32) Sufficient is it for God?s servants to know for a certainty that, for this system under Satan, time is running out rapidly. How foolish a person would be not to be awake and alert to the limited time remaining, to the earthshaking events soon to take place, and to the need to work out one?s salvation!
WT - 8/15/68 - "Are You Looking Forwarded to 1975?":
30
Are we to assume from this study that the battle of Armageddon will be all over by the autumn of 1975, and the long-looked-for thousand-year reign of Christ will begin by then? Possibly, but we wait to see how closely the seventh thousand-year period of man?s existence coincides with the sabbathlike thousand-year reign of Christ. If these two periods run parallel with each other as to the calendar year, it will not be by mere chance or accident but will be according to Jehovah?s loving and timely purposes. Our chronology, however, which is reasonably accurate (but admittedly not infallible), at the best only points to the autumn of 1975 as the end of 6,000 years of man?s existence on earth. It does not necessarily mean that 1975 marks the end of the first 6,000 years of Jehovah?s seventh creative "day."
