We are to count ourselves dead to sin but that doesn't mean we are free from sin. Paul also stated:
Paul knew very well that we as Christians serve the law of sin.
Quite frankly I find Christians who state that they are not subject to sin or do not have sin quite puzzling. I only have to look inside my heart to see corruption. It refreshes me to know that God is taking care of "the mess in the attic" but I'm also well aware of my own inadequacies. As Paul states, thanks be to God that we can serve the law of God because of Christ. All one has to do is look inside themselves to see their own corruption. And that's the very heart of what being a Christian is all about.
Misusing Paul to have a good excuse to still sin. Obviously Paul is talking about before salvation.
you are simply wrong...
1 John 3:7-15
King James Version (KJV)
7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
