John 9:1-5
The first lesson to be learned from this miracle is that sinful man cannot frustrate God. Rather, God accomplishes His purposes sovereignly, saving by grace those whom He chooses to call to Himself. Even man's hatred cannot frustrate God, seen clearly in this miracle story. Jesus seems undisturbed by the religious leaders' attempt to stone Him, an action that would have created great turmoil in the Temple precincts. Yet, a moment later, after Jesus had removed Himself, we find Him stopping beside a blind beggar sitting near the Temple gate. In a similar situation, most of us would scarcely have seen the beggar, being more concerned with being pursued and distancing ourselves from the enemy. Not Jesus!
He had God's perspective and acted accordingly. Therefore, instead of complying with the prohibitions of sinful men, Christ simply perseveres in His task and begins to elect some to salvation. As Paul writes of God in Romans 9:15, "I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion."
The poor blind man symbolizes the state of the lost apart from the creative and transforming power of Christ. On the one hand, the rulers of the people, the Pharisees, can see physically but are spiritually blind. On the other, the blind man cannot see physically, but Christ makes him see both physically and spiritually. By the end of the story, we find him worshipping Jesus as the Son of God.

The Miracles of Jesus Christ: Healing a Man Born Blind (Part One)

Sinful man cannot frustrate God, who sovereignly saves those He chooses by grace. Undisturbed by religious leaders attempting to stone Him, Jesus removes Himself and stops beside a blind beggar near the Temple gate, seeing him with God's perspective. This poor blind man symbolizes the state of the lost apart from Christ's transforming power. Unable to see, seek, or find Jesus, nor procure help, the blind man pictures the spiritual condition of most. Just as He came to His own who did not receive Him, Christ begins calling out a new people, first exemplified in this man. This sixth miracle illustrates Jesus as the Light of the world, giving physical and spiritual sight, testifying to His Deity and Messiahship, while the Pharisees remain spiritually blind.
