Romans 3:30
Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
Seeing it is one God,.... God is one in nature and essence, though there are three persons in the Godhead, Father, Son, and Holy Ghost; whence it appears, that he that is the God of the Jews, is also the God of the Gentiles, or there would be more gods than one; and that these are justified in one and the same manner, or God must be divided; for God, as he is one in nature, so he is one in will, in his promises, and in the methods of his grace:
which shall justify the circumcision by faith, and uncircumcision through faith. The objects of justification are "the circumcision", the circumcised Jews, and "the uncircumcision", the uncircumcised Gentiles; the circumcision of the one does not forward, and the uncircumcision of the other does not hinder, nor neither of them effect the grace of justification: the justifier of them is one and the same, who is God; and the matter of their justification is the same, which is the righteousness of Christ; and the manner of it, or the means of their comfortable apprehension of it, is the same; for those phrases, "by faith", and "through faith", mean one and the same thing; see Philippians 3:9.
