Romans 3:27-28

27Then what becomes of [our] boasting? It is excluded [entirely ruled out, banished]. On what principle? On [the principle of good] works? No, but on the principle of faith.

28For we maintain that an individual is justified by faith distinctly apart from works of the Law [the observance of which has nothing to do with justification, that is, being declared free of the guilt of sin and made acceptable to God].
