aposhitayid, what are you trying to say that it’s ok to say tzaddikim, or in this particular case, the Lubavitche Rebbe, runs the world? That is a fallacy and sorry to be blunt but it is apikorses to believe that.
A tzaddik can be goizer and Hashem will be makayim but only if it His will to do so. Hashem is in full control, He is the One who runs the world. There were many great tzaddikim who were goizer things that never happened, ultimately everything is in the hands of Hashem.
