Six days you shall labor and do all your work. But the seventh day is the sabbath to the Lord your God; you shall not do any work. Exodus 20:9-10
Jesus said to them, "The sabbath was made for humankind." Mark 2:27
I find it amazing that God cares enough for each one of us that he not only gives us guidance and promises, but also gives commands. God knows us better than we even know ourselves. Often one can get involved in a project or task and forget what time it is. Or, maybe one feels the need to work more to earn more no matter what to provide for the life's necessities.  God knows everything about us; therefore, he even instructs us to rest on one day out of seven.
Rest: different things to different people. To one a good book and and a cup of coffee while sitting in a lounge chair might mean rest. To another, travel might fill the bill. Maybe fishing, hiking, or rock climbing may fill the need for outdoor relaxation. Then there is always a nap or watching a favorite team play a sport. You add what fills your need for relaxation. Whatever it is, just know that God is commanding us to take a break from our everyday tasks to restore our bodies, minds, and spirits. Rest is a freedom that each one of us deserves.
We have just celebrated Christmas. For many, this is a time of hectic busyness. Still, we must remember that God expects us to take a moment, no, a day, here and there to rest and collect ourselves. God cares more for us than we can comprehend. His word brings freedom and blessing rather than burdens. Let us heed his command and remember the value of rest. 
Dear Lord and Savior, Jesus Christ, 
Thank you for caring unconditionally for each one of us, your children. You have led us by sharing both promises and commands as guidance for our lives. Give us wisdom to know the freedom of living within your word. Help us to do what is good and right, and to even remember to rest. Help us always to trust in you.  Amen.
