SSF,

You can take any text in the bible out of context and make it what you want. Which is what you have done. Thats not the intent of the book. The book should be treated as a whole and using rules of interpretation as proscribed by biblical scholars forces you to keep things in context . You might see it as pointing fingers because someone challenges your worldview in a discussion. On sin in general I suggest you research it for yourself. It will mean more if you answer that question yourself.
