When the children of Israel crossed over the Jordan river, God instructed Joshua to have 12 men gather stones from the middle of the river and build a memorial to the event on the other side.  When people questioned the stones, they were instructed to tell them of the wonderous thing God had done here.

              I have a memorial in my life.  It is not near as grand as a stone monument but it reminds me of a specific prayer God answered at a time I really needed an answer.
