What is considered Jewish observance? Most people will answer prayer, Torah study, Keeping Shabbos, etc. How about exercise or going to work? These mundane activities are generally not considered to be part of the service of G-d. However, the Mishkan (Tabernacle) in the desert taught us an important lesson. Divine service does not only include 'holy' activities, but it also includes the physical and mundane activities that we engage in.
