John 9:15
Then again the Pharisees also asked him how he had received his sight. He said unto them, He put clay upon mine eyes, and I washed, and do see. Then again the Pharisees also asked him how he had received his sight. He said unto them, He put clay upon mine eyes, and I washed, and do see.
The man born blind had been brought before the Pharisees, and when they questioned him again about how he had received his sight, he answered plainly that Jesus had put clay upon his eyes, and he had washed, and now he sees. The healing he described had taken place on the Sabbath. His plain, direct answer stands as wonderful evidence of the healing itself and of the truth of Christ's divine mission and the transformation He works.
It was a gracious, compassionate act to save and to relieve human suffering. It was given even though the man did not yet know who Jesus was, and he learned Jesus' identity only when Jesus revealed Himself to him as the Son of God. The restored man was one whom Christ compassionately sought to save, though in self-righteousness the Pharisees despised him and treated him with hatred.
The repeated questioning exposes the Pharisees as willfully spiritually blind by choice, making no effort for enlightenment and remaining in darkness. They were hardened by prejudice, unbelief, envy and jealousy over Christ's popularity and His refusal to accept their ideas, hating Jesus for fear He would be honored above them. Their jealousy and unbelief kept them from accepting what the miracle revealed about Jesus' divine mission. They sought to deepen their own blindness and to close the healed man's eyes by smothering his testimony. Their reaction was divided and shaped by hatred of Jesus: some condemned Him as a Sabbath-breaker for supposedly breaking the Sabbath, while others, moved by the miracle, asked whether a sinner could do such works.
