Well if you read things in context, you would know that the works that Paul is referring to are OTHER CHRISTIANS.
As far as the Law of Grace...have you not read that it is written, the Law came through Moses, but Grace and truth came through Jesus Christ. and the Law of Grace is not a codex of rules. It is to love one another as Christ has loved us.
SO did you sacrifice any bullocks at church today, or did Christ fulfill the sacrificial law for you.
Last post to you, because you don't bother to read.
