Vision is something we do not miss until we can not see things as clearly as we once did.  We are unable to read road signs at the distance that we once comfortably read them and it takes longer to focus on things up close.  These are the early signs of vision change.  Jesus linked vision with understanding in this parable in Mark’s gospel. “Mark 4:12-13 That seeing they may see, and not perceive; and hearing they may hear, and not understand; lest at any time they should be converted, and their sins should be forgiven them. 13 And he said unto them, Know ye not this parable? and how then will ye know all parables?”  A parable is a Kingdom of God view of things using something from our natural world.  The purpose of a parable is to correct the perception of a person because perception often times frames our reality. What is real to you is often based on how you perceive it.  Therefore, if you have poor spiritual vision you miss read many of the road signs of life and sometimes because of poor spiritual vision you are not even sure of the distance needed to get to your destination . The corrective lenses for this vision problem is seeking God through the word and revelation of the Holy Spirit. These two spiritual forces will correct your vision problem and will have you seeing like a son of the Kingdom.
