1 As he went along, he saw a man blind from birth. 2 His disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?”
3 “Neither this man nor his parents sinned,” said Jesus, “but this happened so that the works of God might be displayed in him.
In order to understand this verses in it`s proper context you have to look at what Jesus actually ment when he said “But this happened”.
The first time you read this verses you may probably think that “but this happened” is refering to why the man was blind. But is that what Jesus really ment? Or did Jesus mean the the actual meating with the blind man, when he was saying “this happend”?
10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
God have ordained good works for us to walk in. It was not the blindness that manifested the good works of God but the healing! So we can conclude that when Jesus said, “but this happened” it was the works of God that could be displayed through the blind man. It was one more opportunity to reveal Gods love and goodness to the fellowman.
Jesus continues with the following verses to make his point even clearer:
4 As long as it is day, we must do the works of him who sent me. Night is coming, when no one can work. 5 While I am in the world, I am the light of the world.”
As long as it is day – As long we/Jesus are in the world we have the opportunity to do good, only then!
Night is coming, when no one can do the good deeds of god – When we are no longer in the earth (dead) we do not have the opportunity to manifest the goodness of God to others.
Our days on earth passes and will never return. We need to take every opportunity to manifest the goodness of God.
