Romans 2:25

25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.

Ver. 25. If thou keep the law ] Which thou art thereby bound to do, either by thyself, or by thy surety Christ Jesus.

Thy circumcision is made uncircumcision ] Thou art no whit privileged by it. Unregenerate Israel is to God as Ethiopia, Amos 9:7 .
