(Faith comes from what is preached, and what is preached comes from the word of Christ.)
If your lips confess that Jesus is Lord and if you believe in your heart that God raised him from the dead, then you will be saved. By believing from the heart you are made righteous; by confessing with your lips you are saved. When scripture says: those believe in him will have no cause for shame, it makes no distinction between Jew and Greek: all belong to the same Lord who is rich enough, however many ask his help, for everyone who calls his name will be saved.
But they will not ask his help unless they believe in him, and they will not believe in him unless they have heard of him, and they will not hear of him unless they get a preacher, and they will never have a preacher unless one is sent, but as scripture says: The footsteps of those who bring good news are a welcome sound. Not everyone, of course, listens to the Good News. As Isaiah says: Lord, how many believed what we proclaimed? So faith comes from what is preached, and what is preached comes from the word of Christ.
Let me put the question: is it possible that they did not hear? Indeed they did; in the words of the psalm, their voice has gone out through all the earth, and their message to the ends of the world.
The word of the Lord.
