'Keep the Law' in the Bible

Circumcision [the sign of the covenant of Abraham] is indeed of value if you practice the Law; but if you habitually break the Law, your circumcision has become uncircumcision [it is meaningless in God’s sight].

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.
