Jesus says:
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.
