"The KM encouraged the placing of the special October 8, 1966 issue of Awake!, which considered the topic "Why Does God Permit Wickedness?" This issue contained the article "How Much Longer Will It Be?" in answer to the question "when will God bring an end to wickedness?" Under the subheading "6,000 Years Completed in 1975," it reasoned that the millennium would be the last 1000 years of a 7000-year rest day of God. On pages 19-20 it said:
The Bible shows that when God began to shape the earth for human habitation, he worked for six "days," or time periods. From the indications in God's Word, each was apparently 7,000 years in length. Then Genesis 2:22 states, Jehovah "proceeded to rest on the seventh day from all his work that he had made." This seventh day, God's rest day, has progressed nearly 6,000 years, and there is still the 1,000-year reign of Christ to go before its end. (Rev. 20:3, 7) This seventh 1,000-year period of human existence could well be likened to a great sabbath day, pictured by the sabbath day God commanded ancient Israel to keep after working for six days. (Ex. 20:8-10; 2 Pet. 3:8) After six thousand years of toil and bondage to sin, sickness, death and Satan, mankind is due to enjoy a rest and is in dire need of a rest. (Heb. 4:1-11) Hence, the fact that we are nearing the end of the first 6,000 years of man's existence is of great significance.
Does God's rest day parallel the time man has been on earth since his creation? Apparently so. From the most reliable investigations of Bible chronology, harmonizing with many accepted dates of secular history, we find that Adam was created in the autumn of the year 4026 B.C.E. Sometime in that year Eve could well have been created, directly after which God's rest day commenced. In what year, then, would the first 6,000 years of man's existence and also the first 6,000 years of God's rest day come to an end? The year 1975. This is worthy of notice, particularly in view of the fact that the "last days" began in 1914, and that the physical facts of our day in fulfillment of prophecy mark this as the last generation of this wicked world. So we can expect the immediate future to be filled with thrilling events for those who rest their faith in God and his promises. It means that within relatively few years we will witness the fulfillment of the remaining prophecies that have to do with the "time of the end."
Continuing the theme of urgency, the December 1966 KM said (p. 4): "Never have we felt the nearness of Armageddon and the urgency of our work as we do now."
