A Modern Parable

A wise man built his house on an old  WW2 pillbox. The 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 pillbox. 

However, a foolish man, built his house on the sand. The rain came down, the floods came, and the winds blew, and beat on that house; and it fell—and great was its fall.

With apologies to St Matthew
