He who hears these words of Mine, and acts on them, shall be compared to a wise man, who built his house on the rock. The rain fell, the floods came, the winds blew and slammed against that house; yet it did not fall, for it had been founded upon the rock. But he who hears these words of Mine and does not act on them shall be compared to a foolish man who built his house on the sand. The rain fell, the floods came, the winds blew and slammed against that house; it fell— and great was its fall...” (Matthew 7:24-27)
