12For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
13For whosoever shall call upon the name of the Lord shall be saved.
14How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
