It states (25:8) בתוכם ושכנתי מקדש לי ועשו, "They shall make Me a sanctuary and I will dwell in their midst."
It doesn't state בתוכו ושכנתי, "I will dwell in it." It says בתוכם ושכנתי, "I will dwell in their midst." The sefarim explain this to mean that Hashem dwells within every Yid. There is an aron in every Yid. This is his heart. There are keruvim in every Yid. They are his eyes. And all the limbs of a human being correspond to the utensils of the mishkan. Just as Hashem dwelt in the Mishkan, Hashem dwells within every Yid.
It states (Yeshayah 33:15-16) ודבר צדקות הלך אזנו אטם בשחד מתמך כפיו נער מעשקות בבצע מאס מישרים מצדות ישכן מרומים הוא ,ברע מראות עיניו ועצם דמים משמע נאמנים מימיו נתן לחמו משגבו סלעים , "He who walks righteously and speaks honestly, who scorns oppression, who shakes his hands from taking hold of bribe, closes his ear from hearing of blood, and closes his eyes from seeing evil. He shall dwell on high; rocky fortresses shall be his defense; his bread shall be given [to him], his water sure."
The Metzudas Dovid explains, "If he does all of the above, he will dwell in a safe place, as if he is in a high place and the enemy can't get there."
The Targum Yonason translates it as הוא מקדשא בית משרוהי בית יהי ומנטל רם באתר , "He will dwell in a high place, in the Beis HaMikdash." He is explaining that his own home becomes a Beis HaMikdash.
The Divrei Yisrael zt'l said that the Gan Eden of Bnei Yisrael is in Olam HaBa, and the Gan Eden of Hakadosh Baruch Hu is to be in a Yid, as it states (Vayikra 26:12) והלכתי בתוככם , "I will walk within you."
The Midrash tells us that Hashem wants to dwell among us. He doesn't want to be distant from us. The Midrash explains that this is because Hashem loves the Torah, and He wants to be near where there is Torah. Hashem gave us the Torah, so He wants to be near us.
The Midrash states, "Is there a sale that when you buy an item, the seller comes along with it? But Hakadosh Baruch Hu tells Yisrael, 'I sold the Torah to you, keviyachol, I am sold together with it, as it states לי ויקחו, 'Take Me.' It can be compared to a king who had an only daughter. Another king came and married the only daughter. This king wanted to return to his land and take his wife with him. His father-in-law told him, 'This is my only daughter. I can't be distant from her. But I also can't tell you that you can't take her with you because she is your wife. Do me this favor. Wherever you go, make a small room for me so I can dwell there with you because I can't be without my daughter.' Similarly, Hakadosh Baruch Hu tells Yisrael, 'I gave you the Torah. I can't leave it. I can’t tell you not to take it. Rather, wherever you go, make me a room so I can be there. This is the meaning of the words (25:8) בתוכם ושנכתי, 'I will dwell in your midst.'"
The Beis Aharon zt'l would tell his chasidim to learn this Midrash every year. Wherever we are, and with everything we do, make a place for Hashem to be there, too.
