We do not trash the Law. We see the Law is all it's glory and as the highest bar that God has set for man. God Himself not only said no one reaches that that standard, He sent His only Son to measure up to that standard, and to bear the curses of not measuring up to that standard. Anyone who claims they are righteous in any way according to the Law God gave to show how unrighteous man is, and especially after He gave His Son, then gave the Spirit to those who would BELIEVE
shame on all of you who use the Law which was added because of transgressions, to show us how fall we fall short, to build yourself up in some way nearing the righteousness of the Son of God who was with God in the beginning and is God.
The Law is finished. the Law and the prophets were until John. Now we see Jesus. the jewel and fulfillment of everything God gave to man. Including The Law. Not one of you will be found righteous in God's sight according to any portions of any Law.
Your righteousness will be found granted or declared or imputed to by God Himself by your faith in His own testimony about how He alone has reconciled fallen man to Himself.
Jesus is His Name.
