Romans 2:25-29

2:25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision. 2:26 Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision? 2:27 And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law? 2:28 For he is not a Jew, which is one outwardly; neither [is that] circumcision, which is outward in the flesh: 2:29 But he [is] a Jew, which is one inwardly; and circumcision [is that] of the heart, in the spirit, [and] not in the letter; whose praise [is] not of men, but of God.

3:30 Seeing [it is] one God, which shall justify the circumcision by faith, and uncircumcision through faith.
