Anshei Knesset HaGedolah revolutionized Judaism, making it into a religion that could survive Galut, without the Land. At the same time, something essential was lost: Nevuah.
The massive Teshuva that will be, will be towards a Judaism that has Nevuah. Nothing less will do. It will be a Teshuvah to the time before Anshei Knesset HaGedolah. A Teshuva towards a G-d that "existed" before, in Bayit Rishon, and has been waiting ever since, for His People to return.
Now we have returned, under influence of the Bnei Yosef. It is time to complete our return and become Bnei David.
