Romans 3:27-30

Then 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. For 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]. Or is God the God of Jews only? Is He not also the God of Gentiles [who were not given the Law]? Yes, of Gentiles also, since indeed it is one [and the same] God who will justify the circumcised by faith [which began with Abraham] and the uncircumcised through [their newly acquired] faith.
