Romans 2:25-29

Romans 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.

Paul is dealing with the Jew, who was apt to think that he must have a preference beyond the Gentiles on account of his circumcision.

Romans 2:26. Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision? And shall not uncircumcision which is by nature if it fulfill the law, judge thee, who by the letter and circumcision dost transgress the law? For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: 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.

If this principle were fully recognized everywhere, it would certainly put an end to all that notion of sacramentarianism which some men hold. It is not the outward, not the external, not the form and ceremony; it is the inward work of the spirit; it is holiness and change of heart. Let none of us ever fall into the gross error of those who imagine that there is attached to certain ceremonies a certain degree of grace. It is not so. He is not a Christian which is one outwardly, he is a Christian who is one inwardly.

This exposition consisted of readings from Psalms 110:1; Romans 2:25; Romans 3:1.
