14 How 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?

15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings 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.
