Read Romans 2:25 Using Other Translations
For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
For circumcision indeed is of value if you obey the law, but if you break the law, your circumcision becomes uncircumcision.
The Jewish ceremony of circumcision has value only if you obey God’s law. But if you don’t obey God’s law, you are no better off than an uncircumcised Gentile.
