What was the law like from God's point of view?
From God's point of view, the Law was perfect and was the very mind of God. It was not weak or beggarly in itself. Its inability came from man's side, because the Law had no power to help him keep it, but God's own assessment of the Law was perfection.
Les explains that when the Law is analyzed, it was perfect—the very mind of God. It was perfect from God's point of view. The contrast is man's standpoint: the Law was something he could not keep. It was weak and beggarly because, even though it was perfect from God's point of view, man could not keep it since there was no power in the Law to help him. Les illustrates this by recalling that God gave the Law to Moses on cold stone, not a beautiful piece of lambskin. Stone is not cuddly; it is cold and not something you can just bring to yourself. That was the Law: cold, and beggarly, Paul says.
