Romans 2:25 in the World English Bible
For circumcision indeed profits, if you are a doer of the law, but if you are a transgressor of the law, your circumcision has become uncircumcision.
Context
24 For the name of God is blasphemed among the Gentiles through you, as it is written.
25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
26 Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision?
