Genesis 2: 1-3 (NSRV)

[1] Thus the heavens and the earth were finished, and all their multitude. [2] And on the seventh day God finished the work that he had done, and he rested on the seventh day from all the work that he had done. [3] So God blessed the seventh day and hallowed it, because on it God rested from all the work that he had done in creation.

Even God took a rest after completing a job that He was proud of.  Are you proud of the work that you are doing?  That is why we are all here, to do the work that God purposed us for.  So get your rest, but only after doing the work that honors God's purpose for your life.
