Romans 10:14

“How then shall they call on him in whom they, have not believed? etc..] The apostle having observed, that whoever, Jew or Gentile, believe in the Lord and call upon his name, shall be saved; and that the same Lord was ready and willing to dispense his grace, without any difference to them; suggests, that it was therefore absolutely necessary, that the Gospel should be preached to the Gentiles, as well as to the Jews; that it was the will of God it should be; that what he and others did, was by a divine commission; that they were sent by the Lord to preach the Gospel to them; that hearing they might believe, and so call upon the name of the Lord, and be saved; and therefore the Jews ought not…”

“How then shall they call on him in whom they have not believed? and . . . believe in him of whom they have not heard? and . . . hear without a preacher? and . . . preach except . . . sent?--that is, "True, the same Lord over all is rich unto all alike that call upon Him.

His doctrine was, that faith in Christ was essential to justification and salvation; and that this was needful for all; and that, without this, man must perish. The objection was, that they could not call on him in whom they had not believed; that they could not believe in him of whom they had not heard; and that this was arranged by God himself, so that a large part of the world was destitute of the gospel, and in fact did not believe; Romans 10:16-17. The objection had particular reference to the Jews; and the ground of injustice which a Jew would complain of, would be, that the…”

“10:14 It is natural to presume that the pronoun they refers to “all who call on him” from 10:12 or “everyone” from 10:13. While this verse probably does refer to all people, it also continues the accusation against Israel from 10:2-3 (see 10:18). Paul argues that Israel was in a position to know what God was doing through Jesus Christ, so they were culpable for their failure to understand or accept it. Israel was guilty both of failing to understand God’s plan in light of Christ (10:3-4) and of focusing so much attention on the law that they missed Christ when he arrived (9:30-32).”
