10:12 For there is no difference between Jew and Greek. The Jew objected to salvation, instead of by the law. Paul has just shown that righteousness could not be obtained by the law, secondly, that the prophets had predicted salvation by faith. But the Jew is now supposed to object that this salvation was for Jews only, yet Paul is preaching it to the Gentiles. Hence he declares that it is for Greek (Gentile), as well as Jew, as shown by the passage just quoted in Ro 10:11. It says, Every one that believeth, etc. (Isa 28:16). He further shows in Ro 10:13 that
the same Lord over all is rich unto all that call upon him, of whatever race, by a second quotation from the prophets, found in Joe 2:32.
10:12 The same Lord of all is rich - So that his blessings are never to be exhausted, nor is he ever constrained to hold his hand. The great truth proposed in Ro 10:11 is so repeated here, and in Ro 10:13, and farther confirmed, Ro 10:14,15, as not only to imply, that whosoever calleth upon him shall be saved; but also that the will of God is, that all should savingly call upon him.
10:12-17 There is not one God to the Jews, more kind, and another to the Gentiles, who is less kind; the Lord is a Father to all men. The promise is the same to all, who call on the name of the Lord Jesus as the Son of God, as God manifest in the flesh. All believers thus call upon the Lord Jesus, and none else will do so humbly or sincerely. But how should any call on the Lord Jesus, the Divine Saviour, who had not heard of him? And what is the life of a Christian but a life of prayer? It shows that we feel our dependence on him, and are ready to give up ourselves to him, and have a believing expectation of our all from him. It was necessary that the gospel should be preached to the Gentiles. Somebody must show them what they are to believe. How welcome the gospel ought to be to those to whom it was preached! The gospel is given, not only to be known and believed, but to be obeyed. It is not a system of notions, but a rule of practice. The beginning, progress, and strength of faith is by hearing. But it is only hearing the word, as the word of God that will strengthen faith.
