I wanted to comment very briefly on Deuteronomy 29:29 and its connection to the Tabernacle (Mishkan). Let's take a look at the verse:
YLT Dt 29:29 'The things hidden are to Jehovah our God, and the things revealed are to us and to our sons--to the age, to do all the words of this law.
As you can see, this verse implies that Tabernacle is for us and our sons, forever. Torah gives us very clear instructions about Tabernacle and provides all details for us to build it. It was revealed to us, so it is ours. Not God's or some messiah's. Nobody is going to rebuild the Tabernacle for us, except ourselves. So it is up to us to rebuild it.
