If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved.
For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved.
As Scripture says, “Anyone who believes in him will never be put to shame.”
For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on him,
for, “Everyone who calls on the name of the Lord will be saved.”
How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them?
And how can anyone preach unless they are sent? As it is written: “How beautiful are the feet of those who bring good news!”
But not all the Israelites accepted the good news. For Isaiah says, “Lord, who has believed our message?”
Consequently, faith comes from hearing the message, and the message is heard through the word about Christ.
But I ask: Did they not hear? Of course they did: “Their voice has gone out into all the earth, their words to the ends of the world.”
Again I ask: Did Israel not understand? First, Moses says, “I will make you envious by those who are not a nation; I will make you angry by a nation that has no understanding.”
And Isaiah boldly says, “I was found by those who did not seek me; I revealed myself to those who did not ask for me.”
