Job,career or survival?

In the book of Genesis it describes how man 's fall effected his work. It is by the "sweat of our brow" we earn our livelihood. Work is now toil and struggle. But, we had somehow been told that work is to be our identity. Should we return to the notion that work is what we do and Christ is our identity. But we are also told to do our work as unto the Lord as our calling. So, we pour ourselves into our work without losing our identity. Just pray we have work to occupy till He comes.
