20 His parents answered [them] and said, We know that this is our son, and that he was born blind; 21 but how he now sees we do not know, or who has opened his eyes we do not know. He is of age: ask him; he will speak concerning himself. 22 His parents said these things because they feared the Jews, for the Jews had already agreed that if any one confessed him [to be the] Christ, he should be excommunicated from the synagogue. 23 On this account his parents said, He is of age: ask him.

Commentary on John 9:18-23
(Read John 9:18-23)
The Pharisees vainly hoped to disprove this notable miracle. They expected a Messiah, but could not bear to think that this Jesus should be he, because his precepts were all contrary to their traditions, and because they expected a Messiah in outward pomp and splendour. The fear of man brings a snare, Proverbs 29:25, and often makes people deny and disown Christ and his truths and ways, and act against their consciences. The unlearned and poor, who are simple-hearted, readily draw proper inferences from the evidences of the light of the gospel; but those whose desires are another way, though ever learning, never come to the knowledge of the truth.
