Circumcision of the heart

Romans 2:25-29
25 For circumcision indeed is of value if you obey the law, but if you break the law, your circumcision becomes uncircumcision. 26 So, if a man who is uncircumcised keeps the precepts of the law, will not his uncircumcision be regarded [1] as circumcision? 27 Then he who is physically uncircumcised but keeps the law will condemn you who have the written code [2] and circumcision but break the law. 28 For no one is a Jew who is merely one outwardly, nor is circumcision outward and physical. 29 But a Jew is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the letter. His praise is not from man but from God.

... I pray that my heart be circumcised in the Spirit so that I receive praise from God and not the fleeting praise of man. God has blessed so greatly in salvation and deserves all that we have.
