A Living Sacrifice
proper worship is not only offered in church; we are to worship God with our whole lives. Worship is whatever we do in our bodies, which includes absolutely everything.
Holiness is the fundamental character and to be well-pleasing to God the governing principle of a believer. These qualities have reference to his body as well as to his spirit and show how ethical character belongs to the body and to its functions.
The service here in view is worshipful service and the apostle characterizes it as “rational” because it is worship that derives its character as acceptable to God from the fact that it enlists our mind, our reason, our intellect. It is rational in contrast with what is mechanical and automatic. A great many of our bodily functions do not enlist volition on our part. But the worshipful service here enjoined must constrain intelligent volition.
