Even Everyday Life is Sacred
Numbers 3:3

    These are the names of the sons of Aaron, the anointed priests, whom he consecrated to minister as priests.

"Consecrated" means literally "He filled their hands".

            "Anointed" means to be rubbed, or smeared.  The anointed has been marked for special use, with the gifts and powers needed to fulfill the call. (consider 1 John 2:27)  Consecration could be the corresponding life, symbolically given to them in that their hands are filled with the time, experience and work that is part of their calling.  It is similar to the idea of one's destiny being symbolized by the filling of one's cup, and idea that should be remembered when we take Holy Communion.

            Setting aside that relationship between laity and clergy and looking at this in terms of the life of a Christian being a sort of priesthood; it seems that the consecration is their duties as priests, but also the notion that everyday life, which often consists of duties, is sacred and part of what "fills our hands".  We are not part of the family or the priesthood of Aaron, but if as Christians we are, in a way, anointed and consecrated then can we not look at the prayer and work of our days as sacred, the stuff that was "placed in our hands"?  That could be a motivation to follow the command that we do everything, even the everyday work, as if we are working directly for Christ Himself  (Colossians 3:23).

1 John 2:27  But the anointing which you have received from Him abides in you, and you do not need that anyone teach you; but as the same anointing teaches you concerning all things, and is true, and is not a lie, and just as it has taught you, you will abide in Him.

Colossians 3:23  And whatever you do, do it heartily, as to the Lord and not to men.
