Romans 10:14-17

But how will people call on Him in whom they have not believed? And how will they believe in Him of whom they have not heard? And how will they hear without a preacher (messenger)? And how will they preach unless they are commissioned and sent [for that purpose]? Just as it is written and forever remains written, “HOW BEAUTIFUL ARE THE FEET OF THOSE WHO BRING GOOD NEWS OF GOOD THINGS!” [Is 52:7] But they did not all pay attention to the good news [of salvation]; for Isaiah says, “LORD, WHO HAS BELIEVED OUR REPORT?” [Is 53:1] So faith comes from hearing [what is told], and what is heard comes by the [preaching of the] message concerning Christ.
