as he says in Hosea, I will call them my people, who are not my people; and her beloved, who is not beloved:

For there is no difference between Jew and Greek: for the same is Lord of all, rich unto all that call on him.

For every one who may call on the name of the Lord shall be saved.

Then how can they call on him on whom they have not believed? and how can they believe on him of whom they have not heard? and how shall they hear without a preacher?
