Question

With God’s help,
Rabbi, I wanted to ask:
In the penitential prayers, that great ideal of the end of days is mentioned, in which “their burnt offerings and their sacrifices shall be accepted on My altar,” and “for My house shall be called a house of prayer for all peoples.”
What do you think will exist in that state? In what will that acceptance that the burnt offerings and sacrifices express find expression? Will it have some concrete expression? If so, will that expression be on the subjective plane of each and every religious person, and presumably also on the collective plane of each nation? Or also on the physical plane?
For example, is this aspiration really toward some kind of spiritual ecstasy for all humanity? Or more than that? What is that state of “the earth shall be full of knowledge of the Lord as the waters cover the sea”?
 
To the best of my knowledge, in response to questions like these you usually say something like: I don’t know, or we’ll wait and see, or something of that sort. But even so, I assume that you do in fact have some kind of understanding hidden behind these words, and that it does not amount merely to translating them into other words.
