Romans 3:29-31

29Or 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,

30since 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.

31Do we then nullify the Law by this faith [making the Law of no effect, overthrowing it]? Certainly not! On the contrary, we confirm and establish and uphold the Law [since it convicts us all of sin, pointing to the need for salvation].
