I came across this page the other day - from The Watchtower 1967 May 1st article: page 262:
Where Are We According to God’s Timetable?
THE END OF 6,000 YEARS (May1st 1967 p262)
In examining these Scriptural facts, something else also captures our attention. According to Bible chronology, we are already over fifty-two years into the wicked system of things’ “time of the end.” That time began in the autumn of 1914 C.E., at the termination of the “appointed times of the nations,” and it is already far advanced. Jesus said that “this generation” that saw the beginning of this time period in 1914 would also see its end. The generation that was old enough to view those events with understanding in 1914 is no longer young. It no longer has many years to run. Already many of its members have died. But Jesus showed that there would still be members of “this generation” alive at the time of the passing away of this wicked system of things in both heaven and earth. (Luke 21:32, 33) How much longer will it be, then, before God takes action to destroy the wicked and usher in the blessings of his Kingdom rule?
Interestingly, the autumn of the year 1975 marks the end of 6,000 years of human experience. This is ascertainable from reliable chronology preserved in the Bible itself. What will that year mean for humankind? Will it be the time when God executes the wicked and starts off the thousand-year reign of his Son Jesus Christ? It very well could, but we will have to wait to see. Yet of this we can be certain: the generation that Jesus said would witness those events is nearing its close. The time is close at hand. On God’s “timetable” we are in the closing days of a wicked system of things that will soon be gone forever. A glorious new order is immediately before us. This is, therefore, good reason for Christians everywhere to rejoice. Yes, they rejoice because fulfillment of their prayers for the kingdom of God is now at hand.—Luke 21:28.
Therefore, keep in mind the admonition of the Lord Jesus when speaking of our day: “Keep awake, then, all the time making supplication that you may succeed in escaping all these things that are destined to occur, and in standing before the Son of man.” (Luke 21:36) The prophecy is sure; the time is short.
Wow, it must be really, really close now!
