Joshua and the Battle of Jericho

Well, poor little Joshua has had a rough day so far.  He was crying this morning - very upset that he was still "small".  I reassured him and told him that in due time he would grow up and be as big as his daddy.  However, he continued to sob and said, "But I was big when I was at Jericho!"   Hmmmm........how to explain to this boy that he was NOT the Joshua that lived thousands of years ago and fought the Battle of Jericho!
