“Therefore, everyone who hears what I say and obeys it will be like a wise person who built a house on rock.  Rain poured, and floods came.  Winds blew and beat against that house.  But it did not collapse, because its foundation was on rock.  Everyone who hears what I say but doesn’t obey it will be like a foolish person who built a house on sand.  Rain poured, and floods came.  Winds blew and struck that house.  It collapsed, and the result was a total disaster.”
(Matthew 7:24-27 -- GW)
