A Living Sacrifice
When I was coming up, this just meant no smoking, drugs and alcohol (drunkenness), and no premarital sex. Those things are absolutely important and are certainly applicable, but what else are we doing to our bodies?
What are our eating habits like? What is our exercise routines? What are we adorning ourselves with? How much rest and sleep are we getting? I know we as wives and moms serve our husbands and families, but that is not an excuse to neglect our bodies. Can we make sacrifices in physical areas that are pleasing to God?
Are we doing in the body what will help us in the spiritual? Are we offering our bodies by taking care of them, so that we can do Kingdom work here on earth?
The point is this, it's going to be awfully hard to serve God spiritually if our physical man is on the fritz! Let's take care of our bodies, offering them to God by the very things we do in them, so that He can use us to the fullest!
