And as He [Jesus] passed by, He saw a man blind from birth. And His disciples asked Him, saying, Rabbi, who sinned, this man or his parents, that he would be born blind? Jesus answered, neither has this man sinned nor his parents, but he was born so, that the works of God might be manifested in him.
In Verse 1 footnote 2 of the study Bible (which has a nifty online version that you can use) I referred to in my earlier post, the blindness referred to in verse 1 is actually representative of form of death in this book of John, which is mainly about all the kinds of death that can come in to our relationship with the Lord, and on the positive side, all the kinds of healing life that can meet any man’s need. Those who are experiencing blindness, and are unable to know the Lord need “the illumination of the gospel of the glory of Christ” to shine on them (2 Cor. 4:4).
When the light shines on us through the Word, it brings peace and it brings the gospel of the glory of Christ into us for us to know, and for others to be able to read. We are living letters of this gospel (2 Cor. 3:3 – Since you are being manifested that you are a letter of Christ ministered by us, inscribed not with ink but with the Spirit of the living God; not in tablets of stone but in tablets of hearts of flesh), and quite importantly, our individual gospel of what the Lord has done within us to restore us to life is in verse 3; whenever we realize we have a major failure or we wonder why we are a certain way, or why someone who might refuse to believe in God suddenly does, it is so that the works of God might be manifested in him to the glory of God, which is the radiant expression of Him alone.
