I don't know about you but I'm tired of asking people, "How you doing?" and hearing the same one word answer, "Tired!" Here's a novel idea. If you are tired, rest! .
It isn't a suggestion it's actually a command. In fact God set the example, "He completed his work on the sixth day and on the seventh he rested." I don't know if it is a sin or not to not take a day off, but I can tell you from experience and studies it is not smart.
It is proven that you can actually get more done in six days with a day off to rest than you can in seven if you work straight through. Did you know that God even required farmers to give the ground a rest. It makes sense that if God rested and he demanded the ground be given a rest its probably a good idea for you and me.
Enough said, when are you going to take some time off?
