Romanos 10

12 And there is no distinction of Jew and of Greek; for the same Lord of all is rich into all, that inwardly call him.

13 For each man, whoever shall inwardly call the name of the Lord, shall be safe.

14 How then shall they inwardly call him, into whom they have not believed? or how shall they believe to him, whom they have not heard? How shall they hear, without a preacher?

15 and how shall they preach, but they be sent? As it is written, How fair be the feet of them that preach [or evangelize] peace, of them that preach good things.

16 But not all men obey to the gospel. For Isaiah saith, Lord, who believed to our hearing?

17 Therefore faith is of hearing [or by hearing], but hearing by the word of Christ.
