The Bible
Matthew 7:24-27
24"Everyone therefore who hears these words of mine, and does them, I will liken him to a wise man, who built his house on a rock.
25The rain came down, the floods came, and the winds blew, and beat on that house; and it didn't fall, for it was founded on the rock.
26Everyone who hears these words of mine, and doesn't do them will be like a foolish man, who built his house on the sand.
27The rain came down, the floods came, and the winds blew, and beat on that house; and it fell--and great was its fall."
