It's still a fact once 6000+ happens it's the 7th day not the 6th day.
The 7000 year plan is simply a very old mathematical error.
The 7,000 years of this present creation are signed in the heavens and in the Living Oracles committed only to the namesake people of the New Creation Man [Israel is that name], to rehearse until all is fulfilled.
There is also a week of 700 years of ordinary days oracled in the Word.
In the Law/Torah/Living Oracles, there are 140 Jubilee Years of 50 years each, making 140 to the completion of this present creation, at the end of the 7,000 years.
Noah and Methuselah preached for 120 years, which was wisdom doubled [to that which is, as is said in Job], in that it prophesied the end of this present creation at the end of 120 Jubilee years from then.
This present creation is one millennial week, after which is that "Great Day", the 8th Day, and the New Beginning oracled in the Law/Torah/Living Oracles.
The 7th millennial day of this present creation is the Sabbath rest of this present creation, which is oracled in the Law and the prophets. That Sabbath is prophesied by prophets of Israel, esp by Isaiah, and by the prophet Enoch, the seventh from Adam.
What is most interesting in God's 700 year weeks is that they "STOP" being numbered or counted after the resurrection of the LORD, and begin being counted again, after the Gentile Church is removed from the midst of the earth, and God turns to restore the kingdom to Israel [as is promised in Scripture], through and by the period of the Great Tribulation.
This 700 year week is learned from the book of the prophet Enoch, the seventh from Adam [which is canon in the Ethiopian Orthodox Church], in the dream visions. In the dream vision, Enoch writes the oracle of the 10 weeks of 700 years each, making again, 7,000 years, but in those weeks, when the "STOP" happens, Israel loses any mention, and is not mentioned again until after that "STOP" is ended, and then the signs begin again, in Israel, for Israel. Until that happens, there are no signs for this generation but "Jesus Christ and Him crucified", for the preaching of the Gospel in the Gentile Church age.
Then, Israel's ten weeks of 700 years each,begin being counted again, and continue right past the 7th millennium, on into the 8th millennium, the New Creation.
