“Do not let any part of your body become an instrument of evil to serve sin. Instead, give yourselves completely to God, for you were dead, but now you have new life. So use your whole body as an instrument to do what is right for the glory of God” (Romans 6:13)

Stop trying to break a sin-habit and focus on giving that part of your life to God. Draw on the spiritual life of Christ that abides within believers. The Christian is not focused on no longer sinning, but living righteously for God.
