Römer 4:9

Cometh this blessedness then, &c.--that is, "Say not, All this is spoken of the circumcised, and is therefore no evidence of God's general way of justifying men; for Abraham's justification took place long before he was circumcised, and so could have no dependence upon that rite: nay, 'the sign of circumcision' was given to Abraham as 'a seal' (or token) of the (justifying) righteousness which he had before he was circumcised; in order that he might stand forth to every age as the parent believer--the model man of justification by faith--after whose type, as the first public example of it, all were to be moulded, whether Jew or Gentile, who should thereafter believe to life everlasting."

St. Paul observes in this paragraph when and why Abraham was thus justified; for he has several things to remark upon that. It was before he was circumcised, and before the giving of the law; and there was a reason for both. I. It was before he was circumcised, Rom 4:10. His faith was counted to him for righteousness while he was in uncircumcision. It was imputed, Gen 15:6, and he was not circumcised till ch. 17. Abraham is expressly said to be justified by faith fourteen years, some say twenty-five years, before he was circumcised. Now this the apostle takes notice of in answer to the question (Rom 4:9), Cometh this blessedness then on the circumcision only, or on the uncircumcision also? Abraham was pardoned and accepted in uncircumcision, a circumstance which, as it might silence the fears of the poor uncircumcised Gentiles, so it might lower the pride and conceitedness of the Jews, who gloried in their circumcision, as if they had the monopoly of all happiness. Here are two reasons why Abraham was justified by faith in uncircumcision: - 1. That circumcision might be a seal of the righteousness of faith, Rom 4:11. The tenour of the covenants must first be settled before the seal can be annexed. Sealing supposes a previous bargain, which is confirmed and ratified by that ceremony. After Abraham's justification by faith had continued several years only a grant by parole, for the confirmation of Abraham's faith God was pleased to appoint a sealing ordinance, and Abraham received it; though it was a bloody ordinance, yet he submitted to it, and even received it as a special favour, the sign of circumcision, etc. Now we may hence observe, (1.) The nature of sacraments in general: they are signs and seals - signs to represent and instruct, seals to ratify and confirm. They…
