Some of the most complex or hard to understand ideas are understood and accepted by the most uneducated of people. The man born blind in John 9 is a case in point. He was healed of his blindness by Jesus, and knew exactly why.
The man answered, “Why, this is an amazing thing! You do not know where he comes from, and yet he opened my eyes. We know that God does not listen to sinners, but if anyone is a worshiper of God and does his will, God listens to him. Never since the world began has it been heard that anyone opened the eyes of a man born blind. If this man were not from God, he could do nothing.” They answered him, “You were born in utter sin, and would you teach us?” And they cast him out. (John 9:30–34, ESV)
The educated (and to their own minds sinless) religious leaders of the time couldn’t seem to figure it out. More likely they knew but refused to accept. Not so different from so many today who are blind though their eyes work perfectly fine.
Education has a place, but when it feeds an overweening pride it blinds. Here the blind people cast a man who could see out of the congregation (synagogue). We see the same effect today – blind people are casting those of us who can see whole Bible principles out of congregations. So the congregations are made up mostly of blind people. Proof that the religious leaders were not following God’s Word was in the fact they didn’t know from whence Jesus came and refused to follow His teachings.
The blind are convinced they have no sin, and attack any who imply different. The couldn’t biblically dismantle the formerly blind guy’s teaching, so they attacked his character and hit him with the worst they could dish out. Except it didn’t do anything, because he went right back to Jesus and worshiped Him (verse 38).
If your eyes work as they should, worship of Jesus including doing what He did is the natural result. He did what the Father told Him to do, and people who can see are right in line with that. Getting kicked out of the congregation is no indicator of sin or sinlessness. In fact, it might be an indication that your eyesight is very clear.
