From Scripture

                             John 9:1 -41
                             A blind man sees the truth
                             God's power is so great that he can take ordinary materials like dirt and water and perform miracles.  A blind man came to Jesus made a paste out of clay and saliva and spread it on the man's eyes.  Then he encouraged the man to wash to cleanse the dirt from his eyes so he could see.  Sometimes God makes us uncomfortable before revealing his truth to us.
                             This miracle sent the Pharisees into a tizzy and this is how we can tell that they were false shepherds.  Seekers of the truth ask questions sincerely, with a willingness to find God.  The Pharisees were so anxious to hold on to their positions that they made silly conclusions such as, if this man were from God he wouldn't heal on the Sabbath.  In fact, they led people away from Jesus ---- a very serious error.
                             The man believed in Jesus because he saw the truth and believed in it.  When we seek God sincerely with a willingness to obey him, he will always lead us to the truth.
