Romans 10:15

12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, and is rich to all who call on him.

13 For, "Whoever will call on the name of the Lord will be saved."

14 How then will they call on him in whom they have not believed? How will they believe in him whom they have not heard? How will they hear without a preacher?

15 And how will they preach unless they are sent? As it is written: "How beautiful are the feet of those who preach the gospel of peace, Who bring glad tidings of good things!"

16 But they didn`t all listen to the glad news. For Isaiah says, "Lord, who has believed our report?"

17 So faith comes by hearing, and hearing by the word of God.

18 But I say, didn`t they hear? Yes, most assuredly, "Their sound went out into all the earth, Their words to the ends of the world."
