15 And how can men preach unless they are sent? As it is written, “How beautiful are the feet of those who preach good news!” 16 But they have not all obeyed the gospel; for Isaiah says, “Lord, who has believed what he has heard from us?” 17 So faith comes from what is heard, and what is heard comes by the preaching of Christ.

18 But I ask, have they not heard? Indeed they have; for

“Their voice has gone out to all the earth,

and their words to the ends of the world.”
