WPNT(i)
8 So what does it say? “The message is near you, in your mouth and in your heart” (that is, the message of faith that we proclaim):
9 That if you confess with your mouth, “Jesus is Lord”, and believe in your heart that God raised Him from the dead, you will be saved.
10 Because with the heart one believes into righteousness, and with the mouth one promises into salvation.
11 Because the Scripture says: “Everyone who believes on Him will never be put to shame”;
12 because there is no distinction between Jew and Greek, since the same Lord of all is rich to all who call upon Him;
13 because: “Everyone who calls on the name of the LORD will be saved.”
14 How then will they call on Him in whom they have not believed? And how can they believe on Him of whom they have not heard? And how will they hear without someone proclaiming it?
15 And how will they proclaim unless they are sent? As it is written: “How timely is the arrival of those who bring good news of peace, of those who announce the good things.”
16 (However, they did not all obey the gospel; because Isaiah says: “LORD, who has believed our message?”)
