This is to cast a critical eye on living by the Law of the Old Testament, thinking that it will result in success and the kind of righteousness the commands in the Law portray: the NewTestament scriptures paint a picture of that being a failed approach and in fact the way to end up with a righteous life like the Law portrays is to first keep the sayings and commands Jesus preached (albeit He included some of the Law commands in that but went beyond others like replacing 'eye for eye' with 'turn the other cheek') resulting in birth of spirit, then keeping His commands still and His truth that you come to know during the rebirth by Spirit. The result is you protect yourself from wrong doing as empowered by the Spirit to do so. This is a successful approach and tesults in a righteousness which fulfills that seen in the Law.
