14 How then will they call on him in whom they have not believed? And how are they to believe in him uof whom they have never heard?3 And how are they to hear vwithout someone preaching? 15 And how are they to preach unless they are sent? As it is written, w“How beautiful are the feet of those who preach the good news!” 16 But xthey have not all obeyed the gospel. For Isaiah says, y“Lord, who has believed what he has heard from us?” 17 So zfaith comes from hearing, and hearing through the word of Christ.
