As believers, we have died with Christ and have been raised with Him as well into newness of life. Paul's point is to show us that we are new creatures, no longer descended from Adam, the man of sin, but from Christ, the Righteous One. As new creatures, we are part of the Body of Christ, and having died, we are no longer subject to sin. This is how Paul answers the original question in verse 1, asking, "Shall we continue in sin?" That is, is it now acceptable or good to continue violating the Law?

The answer is obviously NO.
