Please recall that there are distinct epochs we are told about (with little enough detail to make it all mysterious) in the future.
There is Yemos Hamoshiach, which we are arguably already in the first stages of, at least according to R’ Shlomo Zalman Auerbach and many others.
There is the idea of Ketz Hayomim, the end of days, the conclusion of history, the fulfillment of the role of Am Yisroel in creation,
There is the idea of tchiyas hameisim, the resurrection of the dead, which would happen around the time of ketz hayomim,
And then there is the often confused concept of Olom Haboh, which in normative use refers to the reward a neshama gets after its temporal life is ended, but which has sometimes been conflated with some of the elements of our “end times”.
The truth is that we know little enough and the only certainty we have of any of the details of it is in our bitochon.
