Romans 10:8; Romans 10:17-18

8 But what saith it ? The word is nigh thee, even in thy mouth, and in thy heart: that is , the word of faith, which we preach ;
17 So then faith cometh by hearing, and hearing by the word of God. 18 But I say , Have they not heard ? Yes verily, their sound went into all the earth, and their words unto the ends of the world.
