If you believe that faith is everything, and works count for naught, then you elaborate an ancient controversy. And so I suspect neither you or I have the answer to it.
If only Christ's righteousness is acceptable to God, then why did God sacrifice His Son to redeem mankind?
If God Himself submitted to this Sacrifice, then do you think He might possibly have had a more favorable "opinion" of mankind, His creature, than you seem to have? A Sacrifice made for the purpose of renewal and resumption of the "in the Beginning" divine/human communication that existed before Man fell -- and took the world with him?
