Romans 10:11

8 But what saith it? The word is nigh thee, in thy mouth, and in thy heart: that is, the word of faith, which we preach:

9 because if thou shalt confess with thy mouth Jesus [as] Lord, and shalt believe in thy heart that God raised him from the dead, thou shalt be saved:

10 for with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.

11 For the scripture saith, Whosoever believeth on him shall not be put to shame.

12 For there is no distinction between Jew and Greek: for the same [Lord] is Lord of all, and is rich unto all that call upon him:

13 for, Whosoever shall call upon the name of the Lord shall be saved.

14 How then shall they call on him in whom they have not believed? and how shall they believe in him whom they have not heard? and how shall they hear without a preacher?
