Expositor's Bible Commentary Commentary John 9:35

"Jesus heard that they had cast him out; and finding him, he said, Dost thou believe on the Son of God?" — John 9:35 (ASV)

In contrast to the negative result of rejection is the positive result of Jesus’ response. “Found” implies that Jesus looked for the man so that he might confirm his faith. The question “Do you believe in the Son of Man?” is a summons to commitment, demanding a personal decision in the face of opposition or rejection. Since the healing of the man occurred after Jesus’ first interview, he would not have recognized Jesus by sight; and the question, couched in the third person, would not instantly identify the questioner as the object of faith.
