Romans 2:13, 27

For it is not those who merely hear the Law [as it is read aloud] who are just or righteous before God, but it is those who [actually] obey the Law who will be justified [pronounced free of the guilt of sin and declared acceptable to Him].

Then he who is physically uncircumcised but keeps [the spirit of] the Law will judge you who, even though you have the written code and circumcision, break the Law.
