Now it is clear that no one is justified [that is, declared free of the guilt of sin and its penalty, and placed in right standing] before God by the Law, for “The righteous (the just, the upright) shall live by faith.”

You have been severed from Christ, if you seek to be justified [that is, declared free of the guilt of sin and its penalty, and placed in right standing with God] through the Law; you have fallen from grace [for you have lost your grasp on God’s unmerited favor and blessing].

I have confidence in you in the Lord that you will adopt no other view [contrary to mine on the matter]; but the one who is disturbing you, whoever he is, will have to bear the penalty.
