Sanctification Questions: Grace and Law

After Paul proclaims Justification by Faith Alone in Christ Alone and its guarantee unto glorification in Romans 1-5, he parenthetically deals with the questions of Sanctification that will likely be asked. "If I am justified by Christ's works alone by grace that is greater than my sin, why do I care about sin at all now?" "If Christ has fulfilled the Law of God in my place, why do I care about the Law at all now?"

Paul uses four questions in all to discuss the relationship of sin and grace in Romans 6 and then sin and the law in Romans 7. In summary, we find motivation and obligation to grow in sanctification because those who are justified in Christ have a New Identity in Christ, a New Master of Christ, a New Relationship with the Law, and a New Struggle with the Law.
