Romans 10:13

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 For with your heart you believe and are justified, and with your mouth you confess and are saved.

11 It is just as the Scripture says: “Anyone who believes in Him will never be put to shame.”

12 For there is no difference between Jew and Greek: The same Lord is Lord of all, and gives richly to all who call on Him,

13 for, “Everyone who calls on the name of the Lord will be saved.”

14 How then can they call on the One in whom they have not believed? And how can they believe in the One of whom they have not heard? And how can they hear without someone to preach?

15 And how can they preach unless they are sent? As it is written: “How beautiful are the feet of those who bring good news!”

16 But not all of them welcomed the good news. For Isaiah says, “Lord, who has believed our message?”

17 Consequently, faith comes by hearing, and hearing by the word of Christ.
