Is the law holy and perfect according to Les?
Yes. The law is holy and perfect, but it had no power to help mortal man keep it. That was its weakness; it could not impart the power needed, so people in the flesh could not keep it, not even come close.
Les teaches that the law is perfect and holy from God’s point of view, but because man without the Holy Spirit is in his own flesh, he couldn’t begin to keep that perfect law. The law had no power within it to help the law keeper keep it; that was its weakness. Under grace, however, Grace Age believers can have the righteousness of the law fulfilled in them through the power of the Holy Spirit.
