Romans 10:
14 How then shall they call on him in whom they have not believed? and how shall the believe in him of whom they have not heard? and how shall they hear without a preacher?
15 And how shal they preach, except they be sent? as it is written, HOW BEAUTIFUL ARE THE FEET OF THEM THAT PREACH THE GOSPEL OF PEACE, AND BRING GLAD TIDINGS OF GOOD THINGS!
16 But they have not all obeyed the gospel. For E-sa'-ias saith, LORD, WHO HATH BELIEVED OUR REPORT?
17 So then faith cometh by hearing, and hearing by the word of God.
Matthew 7:
24 Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
25 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
26 And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:
27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.
