Did G-d presently do an action in preparing the Land of Israel to eventually absorb the people of Israel, or did G-d just verbally designate the Land of Israel to eventually absorb the people of Israel?

If G-d did an action, why is not clearly stated in the verse?

If G-d's action was only in the celestial realm, nevertheless, should this not have a visible effect on its terrestrial counterpart?

Does the existence of the heavenly Temple depend upon a present existence of the earthly Temple?

Lastly, in cases where "mere designation" is a "significant matter" would this apply even if the designation was through mere speech, or is an action necessary?

These are the questions the Rebbe will clarify in this sicha.
