Awake, 10/8/1968, p. 14, The seventh one-thousand year period could be likened to the seventh day, the sabbath of that week. 2 Pet. 3:8. How fitting it would be for God, following that pattern, to end man's misery after six thousand years of human rule and follow it with His glorious Kingdom rule for a thousand years!... This would leave only seven more years from the autumn of 1968 to complete 6,000 years of human history. That seven-year period will evidently finish in the autumn of the year 1975."
Kingdom Ministry, 3/68, p. 4, "Just think, brothers, there are only about 90 months left before 6,000 years of man's existence on earth is completed. Do you remember what we learned at the assemblies last summer? The majority of people living today will probably be alive when Armageddon breaks out, and there are no resurrection hopes for those who are destroyed then. So, now more than ever, it is vital not to ignore that spirit of wanting to do more."
Kingdom Ministry, 6/69, p. 3: "In view of the short time left, a decision to pursue a career in this system of things is not only unwise but extremely dangerous... Reports are heard of brothers selling their homes and property and planning to finish out the rest of their days in this old system in the pioneer service, this is a fine way to spend the short time remaining before the wicked world's end."
Paradise Restored to Mankind by Theocracy! pp. 364-365: "Jehovah, the God of the true prophets, will put all false prophets to shame either by not fulfilling the false predictions of such self-assuming prophets or by having His own prophecies fulfilled in a way opposite to that predicted by the false prophets. False prophets will try to hide their reason for feeling shame by denying who they really are. "
