Sin must no longer rule in your mortal bodies, so that you obey the desires of your natural self. Nor must you surrender any part of yourselves to sin to be used for wicked purposes. Instead, give yourselves to God, as those who have been brought from death to life, and surrender your whole being to him to be used for righteous purposes.” (Romans 6:12–13, GNB)

Paul tells the church in Corinth that when anyone comes to faith in Christ they are “a new creation, old things have passed away, all things have become new” (2 Cor 5.17).  He works out what the actually looks like here in Romans.  There is a putting off and there is a putting on.

Putting off:  We put off sin as our master – Since Christ is our master, both sin and Christ cannot reign in our lives, it must be one or the other.  Paul says to put off sin as a constraining power in our lives.

Putting on: We surrender our whole being to God “to be used for righteous purposes.  Sin has been cast off, rather than surrender to sin [as we had been doing before we were saved] we yield to the power and direction of God in our lives.

As Bob Dylan once wrote:  “You’re gonna have to serve somebody.  It may be the devil, it may be the Lord, but you’re gonna have to serve somebody.”  We’d like to convince ourselves that we are the masters of our own fate and we only serve ourselves, but of course we are wrong.  Before we come to Christ we are enslaved completely by sin. Freedom from slavery is possible…in Christ, but we’re serving one or the other.
