Life is full of things that we "have to do." Not just working, but brushing our teeth, washing dishes, taking showers, going food shopping, and sleeping. When I get out of work in the afternoon, I'm not any more "free" than I was when I was being paid to serve people coffee. I still "have" to do a lot of things. Life is just one "have to do" after another. But to do all of the "have to dos" joyfully and to the Lord is freedom. All actions become sanctified.
