Romans 10:14-17

But before people can ask the Lord for help, they must believe in him; and before they can believe in him, they must hear about him; and for them to hear about the Lord, someone must tell them; and before someone can go and tell them, that person must be sent. It is written, “How beautiful is the person who comes to bring good news.” But not all the Jews accepted the good news. Isaiah said, “Lord, who believed what we told them?” So faith comes from hearing the Good News, and people hear the Good News when someone tells them about Christ.
