Matthew 7:24-29; Luke 6:47-49. Therefore everyone who hears these words and does them shall be likened to a wise man who built his house upon the rock. And the rain came down, and the floods came, and the winds blew and beat upon that house, yet it did not fall, for it was founded upon the rock. And everyone who hears my words and does not do them shall be like a foolish man who built his house upon the sand. And the rain came down, and the floods came, and the winds blew and beat upon that house, and it fell, and great was its ruin. And it came to pass, when Jesus had finished these words, the crowds were astonished at his teaching.
