With in the scriptures there are different occasions where Our Lord refers to the eyes being opened.   The first occasion is in the book of Genesis, whereby Adam and Eve had their eyes opened and knew they were naked.  (the Old Testament)

The next is in the occurance of the conversion of Saul to Paul.   (The New Testament)   In both cases we can see Our Lord proves our sinfulness blinds us.

In fact the ‘truth’  is sin is blindness.   In we see in two different perspectives.    One when we choose to be spiritual the other when we choose the flesh.   Gods awareness in both occurances is why we have Jesus Christ.   He is the ‘truth’.   Unfortunatley, it takes great courage to, ‘look at the truth’ and desire to remain in the truth.    Jesus states, “I am the way, the truth and the life.”   He refernces this countless times.   The parable is, that to come to Christ is to come into the light. Christ is the light of the world.   In the ocurrance of ‘Oringial Sin, ‘  darkness, which is sin, covered the world.

 If only the world would see  through the ‘eyes of Christ’ then it would  be  in the light again.  

 Until the world claims Jesus as the light of the world and welcomes Him as the King of Kings and Lord of Lords that He is, only then can the darkness leave the earth.

Since Jesus is the light, His reflection of each of us, and His desire to perfect us in His image is constant.   For to stay in the light is essential.   We can only achieve the light constantly, by choosing to refrain from the darkness, which is sin.

Darkness, and sin being the same, because they are the core of Satans desires.   The sin that people choose ‘blinds them spiritually’.   When the spirit is in sin, it is not in the light.  Though stating the obvious, many do not realize to maintain a higher spiritual realm, they must refrain from sin.   Sin, in all the books of the Bible, is constantly trying to deter us from the light of the world, who is Jesus Christ.   So, when one is ‘walking in darkness’ He has not been  made ‘anew’ in the light of Christ.   For to come to Christ and love Christ is to embrace Christ, His teachings, His life, and His desires.   For He and the Father are One in the Holy Spirit. 

Thereby the Holy Trinity is then a constant presence within us when we embrace the love of Christ our Lord and Savior.

17″I have delivered you from this people and from the nations, 18) to open the eyes of those to whom I am sending you, to turn from darkness to light and from dominion of Satan to God; that through their  faith in me thay may obtain the forgiveness of their sins and a portion among God’s people”. 

Book of John, Chapter 12: 44-48  Jesus Proclaimed aloud:

44)”Whoever puts faith in me believes not so much in me as in him who sent me;   45)and whoever looks on me is seeing him who sent me.   46)I have come to the world as its light, to keep anyone who believes in me from remaining  in the dark.  47)If anyone hears my words and does not keep them, I am not the one to condemn him, for I did not come to condemn the world but to save it.   48) Whoever rejects me and does not accept my words already has his judge, namely, the word I have spoken- it is that which will condemn him on the last day.   49)For I have not spoken on my own; no, the Father who sent me has commanded me what to say and how to speak.   50)Since I know that his commandment means eternal life, whatever I say is spoken just as he instructed me.”

Book Of John: Chapter 8 Verses  31-32  

31)Jesus  then went on to say to those Jews who believed in him:

“If you live according to my teaching, you are truly me disciples; 32)then you will know the truth and the truth will set you free.”
