Romans 10:15-18
10:15 And how are they to preach unless they are sent? As it is written, “How timely is the arrival of those who proclaim the good news.”
10:16 But not all have obeyed the good news, for Isaiah says, “Lord, who has believed our report?”
10:17 Consequently faith comes from what is heard, and what is heard comes through the preached word of Christ.
10:18 But I ask, have they not heard? Yes, they have: Their voice has gone out to all the earth, and their words to the ends of the world.
