Mark 2:27 Then he said to them, ‘The Sabbath was made for man, not man for the Sabbath.
God made the Sabbath for us and for a reason. He did not have some spare time to take a day off; God started the Sabbath for our good.
Working your socks off to try and make a success of your business or to earn more money is not going to be good for your health; it may fill your pockets but at the cost of your wellbeing!
God knows this and so made the Sabbath so we would take time off to be closer to Him. He did not make it just so we would take time off but so we would enjoy our time off with Him!
