What does John 9:34 mean?
These scribes and Pharisees have attempted to debunk Jesus' latest miracle. They've interrogated the man who was born blind (John 9:13) and subsequently healed (John 9:6–7). They've questioned the man's parents (John 9:18). They've taken a second look at the healed man's testimony (John 9:24). That second exchange led to embarrassment for the religious leaders. The formerly blind man's sincere-but-sarcastic responses showed these men were nothing more than religious hypocrites. They claimed not to know where Jesus was from; the healed man said Jesus' miracles were evidence enough of who He was (John 9:25). The scribes and Pharisees claimed Jesus was a "sinner;" the healed man pointed out that a "sinner" wouldn't have access to God's power (John 9:30–33).In response, these men once again resort to a typical reaction: personal attacks (John 9:28). In logic and debate, this is known as an ad hominem, which literally means "to the man." This is where one side insults or disparages the person rather than dealing with the issue itself. Here, the scribes and Pharisees dismiss the once-blind beggar with yet another insult. These same men used insults instead of reason (John 8:48) against Jesus, as well. In fact, their verbal abuse resembles what they said to Jesus in questioning His birth (John 8:41). This healed man is experiencing the same kind of hatred, from the world, which Christ Himself received (John 15:18–21).
This man's experience is a living parable for what it means to convert to Christianity. He is given a "sight" he never before possessed (John 9:1–2), by someone he had never before known (John 9:11–12). The only thing he knows for certain is the effects of this change on his own life (John 9:25). Then, when he stands up for the truth of his own experience, the world insults and abuses him (John 9:28, 34), much the same way it did Jesus.
In the next passage, this blind man will finally see Jesus, who had sent him off to complete the healing miracle by washing his eyes (John 9:6–7). Jesus will fill in the last gaps in this man's knowledge, resulting in his salvation (John 9:38).
John 9:13–34 describes the Pharisees' reaction to Jesus' healing of a man born blind. Rather than being swayed by an obvious sign of divine power, they look for excuses and criticisms to discredit the miracle. They interrogate the man's parents, who timidly defer back to their son. The healed man knows nothing more than this: ''though I was blind, now I see.'' His matter-of-fact responses to the Pharisees highlights their obvious prejudice. As a result, they excommunicate the healed man from the synagogue. Jesus will meet with the man in the next passage to give more context for the miracle.
Jesus encounters a man who has been blind his entire life. Consistent with notions of that era, the disciples assume the disability is due to some specific sin: either the man's or his parents'. Jesus challenges this idea and heals the man. His restoration leads to interrogation. The Pharisees try to discredit Jesus' miraculous work. The healed man's simple, straightforward perspective embarrasses the religious leaders, who excommunicate him in frustration. Jesus meets with the healed man, explaining more about His identity and the purpose of His ministry. Jesus also reminds the Pharisees that those who ought to know better, spiritually, will be held more accountable as a result.
