Simon is Sammy and Miriam’s friend who writes a letter to share the stories he heard Jesus tell about his Kingdom.  The rich man whose riches were lost, the blind men both falling in a ditch, and the girl with a large chip of wood in her eye trying to remove a speck of sawdust from her friend’s eye were all stories teaching about God.  Our treasure should be in Heaven and a blind man can’t keep his blind friend from falling into a ditch!
