If we want Hashem to dwell in the midst among us klal yisroel his holy loving nation then we need to live up to the means of living on the level of ruchnius and frumkeit to be deserving and to be holy enough to have Hashem dwell in our midst.
I.e. how can a person expect a person to dwell in his home filled with non tznuis magazines and an atmosphere of a non jewish home of sports and TVs etc… With not kosher things to see?
How can a loving nation klal yisroel expect Hashem to dwell in our midst when we are filled with running after every desire and pleasure non stop and using non kosher smartphones with tons of tumah posted on it etc….
These are just a few examples but each person privately should be blessed to know exactly what they need to remove from themselves to be blessed to have Hashem dwell in his midst of his physical home where he lives and his spiritual home and life w4-7
