Paul continues to demonstrate why the grace of God does not incite more sin. In this section, we see that living under grace doesn't mean that we are free to sin. It means that we have been freed from our old master in order to serve our new one. Believers are free from the dominion of sin and now serve Christ. This doesn't mean that believers no longer sin but they are no longer obeying the master of sin, now there is a fight that takes place - and the end of this fight is eternal life for believers.
