Romans 10:9-10, 16-18

If you openly declare that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For it is by believing in your heart that you are made right with God, and it is by openly declaring your faith that you are saved.

But not everyone welcomes the Good News, for Isaiah the prophet said, “LORD, who has believed our message?” So faith comes from hearing, that is, hearing the Good News about Christ. But I ask, have the people of Israel actually heard the message? Yes, they have: “The message has gone throughout the earth, and the words to all the world.”
