John 9:2-3; John 9:18; John 9:20; John 9:22-23

2 And his disciples asked him, saying , Master, who did sin , this man, or his parents, that he was born blind? 3 Jesus answered , Neither hath this man sinned , nor his parents: but that the works of God should be made manifest in him.
18 But the Jews did not believe concerning him, that he had been blind, and received his sight , until they called the parents of him that had received his sight .
20 His parents answered them and said , We know that this is our son, and that he was born blind:
22 These words spake his parents, because they feared the Jews: for the Jews had agreed already, that if any man did confess that he was Christ, he should be put out of the synagogue. 23 Therefore said his parents , He is of age; ask him.
