Romanos 10

12 For there is no difference between the Jew and the Greek, for the same Lord over all is rich unto all that call upon him.

13 For whosoever shall call upon the name of the Lord shall be saved.

14 How then shall they call on him in whom they have not believed? and how shall they believe him of whom they have not heard? and how shall they hear without a preacher?

15 And how shall they preach if they have not been sent? as it is written, How beautiful [are] the feet of those that announce the gospel of peace, of those that announce the gospel of that which is good!

16 But not everyone hearkens unto the gospel. For Isaiah says, Lord, who has believed our report?

17 So then faith [comes] by hearing, and [the] ear [to hear] by the word of God.
