Romans 10:11-14

10:11 For the scripture says, “Everyone who believes in him will not be put to shame.” 10:12 For there is no distinction between the Jew and the Greek, for the same Lord is Lord of all, who richly blesses all who call on him. 10:13 For everyone who calls on the name of the Lord will be saved.

10:14 How are they to call on one they have not believed in? And how are they to believe in one they have not heard of? And how are they to hear without someone preaching to them?
