Matthew 7:24-27
24. Therefore everyone who hears these words of Mine and acts on them, may be compared to a wise man who built his house on a rock. 25. 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. 26. 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. 27. The rain fell, and the floods came, and the winds blew and slammed against that house; and it fell — and great was its fall.
