“It was God himself who directed the details of the Tabernacle. We are beings made by God with the ability to sense our environment. God speaks to us through our senses.”

Reason less and focus on scripture more. God does not care about externals - it is what is in our hearts that matters.
Acts 17:24 (NIV)
24 The God who made the world and everything in it is the Lord of heaven and earth and does not live in temples built by human hands.
Yet in Hebrews we are told to keep the fellowship with other believers as well.
It is not God that needs externals, it is us. That is why Scripture itself tells us that He commanded that the Tabernacle and its worship be something beautiful.
