Sefer Beis HaBechira on RaMbaM pages 97, 5, 98. Do we build the Beis HaMikdash as the RaMbaM holds or does Hashem biuld it as RaShI and Tosefos hold. Four or five answers: 1) We put up the doors and the rest comes from heaven. 2) Zachu from heaven, Lo Zachu we have to build it. 3) We do the Mitzva of building the physical Beis HaMikdash, and the heavenly house is added (spiritually) above and beyond what we build. Like the fire from above which is added to the fire built by people on the Mizbeach. 4) We build the parts we can make sense out of from Yechezkel, the rest comes from heaven. 5) Korbonos (our Job) vs. the Shechina (Hashem’s job).
