14 How then shall they call on Him in whom they have not believed? And how are they to believe in Him of whom they have not heard? And how shall they hear apart from a preacher? 15 And how shall they preach unless they are sent? Just as it is written:

"How beautiful are the feet of those who preach the gospel of peace,

of those preaching the gospel of good things!"

16 But they have not all obeyed the gospel. For Isaiah says, "Lord, who has believed our report?" 17 So then faith comes by hearing, and hearing by the word of God.
