John 9:5
Jesus repeats the claim "I am the light of the world" which he stated in John 8:12, "I am the light of the world.  Whoever follows me will not walk in darkness, but will have the light of life."  John 1:9 says "The true light, which gives light to everyone, was coming into the world."  The rest of the passage explains that He made the world, but it didn't know Him.  Even His own people didn't know Him, but to those who believed Him to be the true light, He gave the right to become children of God.  John 3:19-21 tells us the judgment of the world is because people loved darkness and hated the light because the light exposed their wickedness.

The events recorded in John 9 display these truths.  The man was blind not because of sin, but so the light of the world could be displayed through him.  The man who was previously blind accepted Jesus for who He was.  Look at the progression of the man's claims about Jesus in John 9:11, 17, 25, 30-33, 35-38.  The Pharisees said Jesus was not from God (v 16) even though they admitted he healed a man born blind (v 26), and they didn't disagree when the blind man told them this had never happened before (v 32). He was correct in that no one in the OT was ever healed of blindness.

Jesus' statement in John 9:39, "For judgment I came into this world, that those who do not see may see, and those who see may become blind."  Since Jesus is the true light of the world, only those in the light see.  In John 9:40 some Pharisees question Jesus' statement by asking "Are you saying we are blind?"  Jesus' answer is since you say you see, your guilt remains.  They willfully refused to see even when the Light of the World gave sight to a man born blind.  They loved their darkness and self-interest more than the light.   Matthew 6:22-23 addresses their problem, "The eye is the lamp of the body.  So, if your eye is healthy, your whole body will be full of light, but if your eye is bad,  your whole body will be full of darkness.  If then the light in you is darkness, how great is the darkness."  How "bad" were the eyes of the Pharisees?  How great was their darkness?

Thank You, Jesus, for eyes that see "You are the Christ, the Son of the living God."  

Proverbs 6:16-19
As I read this list of what the LORD hates and are an abomination to Him, I am struck by what He hates.  He hates the sinful use of my eyes, tongue, hands, heart, and feet.  The last two things on the list, a false witness and a man who stirs up dissension are done with the tongue, usually a lying tongue.  How amazing is the human body with all its various capabilities for evil or good!

Our eyes can be haughty or bountiful (Proverbs 22:9); my tongue can lie or heal (Proverbs 12:18), my hands can shed blood or make rich (Proverbs 10:4), my heart can devise evil plans or give life (Proverbs 14:30) and my feet can rush to evil or be beautiful as they bring good news (Isaiah 52:7).

Lord God, thank You for the physical body You have given me.  May my body be a living sacrifice, holy and acceptable to You as my spiritual worship.  Holy Spirit, please teach me to use all of my physical gifts for good and not evil.
