The proclamation of the law makes me aware that I am born of a branch that is already cut off from the source of life.a branch that has already violated the perfect law of being .that has already interrupted that perfect life bringing flow causing its severance and ultimate death.
Thus the law brings to my knowing that I am doomed ,both in being grown from a branch already cut off from life and in the truth that I myself by willfully action did violate that same perfection and so all that comes forth from me also will end in that same death. It also makes me aware that even if I did not yet wilfully violate that perfect law of being in its perfect and harmonious flow of life,I am born of a corrupted seed already tainted by that violation and thus lays in me the full propensity and desire to so violate that perfection even if I never chose that propensity.
So.. through the declaration of the perfect righteousness of God It is unambiguously made known to me ,that through and through..I am condemned .The most wretched of men.
And without hope in the world.for no action taken by the violator can undo that which is violated .
No more can my helpless state be remedied by myself,then can a branch of a tree ,cut off and laying upon the ground ,pick itself up and graft itself back into the tree of life from whence it came.
I ,like it,am altogether helpless.and doomed to eternal death.
So,for the sinner,now made aware of their state the usefulness of that perfect law made known is righteous and perfect in proving me sinful and condemning me .
Thus ,I am condemned ,before I knew of it(in sin did my mother conceive me) in the revelation of it (for God is declared righteous and I,a sinner) and in the continued knowledge of it.
And there ends the usefulness of the perfect law of God in regard to my eternal state .for its usefulness in its unbroken state is eternal life buts it's declaration on tablets of stone to those who have broken it,has ,in every conceivable and perfect way,fulfilled the purpose of its declaration.
It has proven God's righteousness and proven my lack of righteousness.
It has fully proven the woeful state of impending death in which the cut off branch already exists .it has shown me that I am already dead (cut off,severed from the vine of life)in sin.I am already fallen.
And where the law is perfect in doing so.it ends its usefulness of life toward me ,in that,it condemns me and there ,leaves me.
