I woke up feeling pretty cruddy; I'm fighting a chest cold. Probably from being so busy before I left and then traveling.
I'm often amazed that God built a day of rest into each week. It's one of those things that really helps me to conceptualize that He really cares for us and knows what we need even more than we do.
We all recharge in different ways, but we do need to recharge or our bodies start drawing energy from alternate sources, which aren't as good for us.
I'm grateful for the Sabbath and a God that loves us enough to account for our needs.
