Observe the sabbath day and keep it holy, as the Lord your God commanded you. Six days you shall labor and do all your work. But the seventh day is a sabbath to the Lord your God; you shall not do any work--you, or your son or your daughter, or your male or female slave, or your ox or your donkey, or any of your livestock, or the resident alien in your towns, so that your male and female slave may rest as well as you. Remember that you were a slave in the land of Egypt, and the Lord your God brought you out from there with a mighty hand and an outstretched arm; therefore the Lord your God commanded you to keep the sabbath day.
 

Is not the command to rest and remember on the Sabbath partly a command to labor on the other days?  For this labor on the other six days is the fulfillment of the command which comes down to us from the dawn of man: “in toil and by the sweat of your face you shall eat” (Genesis 3.17-19)

Toiling and sweating on the six days causes us to remember our fallen condition: that we are not yet with Christ.  It is a redeemed labor, however, and so can bring us joy.  But it is also a constant reminder of our days in Egypt, of our days of servitude to the world from which we have been liberated: ‘Remember that you were a slave in the land of Egypt, and the Lord your God brought you out from there’ (Deuteronomy 5.15)

Rest and remembrance, then, is what we look forward to on the Sabbath.  Rest and remembrance await us after this life.  Can remembrance be possible without rest?  Is rest meaningful without remembrance?  Indeed, it seems the best, most refreshing rest comes when it is accompanied by remembrance.  It seems what we speak of here is recollection, that state by which we keep ourselves in the presence of Christ, or shall we say offer ourselves to him in obedient submission to the Father’s will that we labor, rest and remember the salvific action of the Son, who out of all things acts out of, and for, love.
