Matthew 7:24-27  NAS

"Therefore everyone who hears these words of Mine and acts on them, may be compared to a wise man who built his house on the rock.  And the rain fell, and the floods came, and the winds blew and slammed against that house; and yet it did not fall, for it had been founded on the rock.  Everyone who hears these words of Mine and does not act on them, will be like a foolish man who built his house on the sand.  The rain fell, and the floods came, and the winds blew and slammed against that house; and it fell -- and great was its fall."
