Encountering a man blind from birth, the disciples assumed that the cause for his blindness must have been someone’s sin. Jesus, however, told them that his blindness was so that the work of God might be displayed in him. The remedy for our spiritual blindness is receiving spiritual sight as an undeserved gift from the Lord Jesus.
John 9:1-25 ESV
Jesus Heals a Man Born Blind
9 As he passed by, he saw a man blind from birth. 2 And his disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?” 3 Jesus answered, “It was not that this man sinned, or his parents, but that the works of God might be displayed in him. 4 We must work the works of him who sent me while it is day; night is coming, when no one can work. 5 As long as I am in the world, I am the light of the world.” 6 Having said these things, he spit on the ground and made mud with the saliva. Then he anointed the man’s eyes with the mud 7 and said to him, “Go, wash in the pool of Siloam” (which means Sent). So he went and washed and came back seeing.
8 The neighbors and those who had seen him before as a beggar were saying, “Is this not the man who used to sit and beg?” 9 Some said, “It is he.” Others said, “No, but he is like him.” He kept saying, “I am the man.” 10 So they said to him, “Then how were your eyes opened?” 11 He answered, “The man called Jesus made mud and anointed my eyes and said to me, ‘Go to Siloam and wash.’ So I went and washed and received my sight.” 12 They said to him, “Where is he?” He said, “I do not know.”
13 They brought to the Pharisees the man who had formerly been blind. 14 Now it was a Sabbath day when Jesus made the mud and opened his eyes. 15 So the Pharisees again asked him how he had received his sight. And he said to them, “He put mud on my eyes, and I washed, and I see.” 16 Some of the Pharisees said, “This man is not from God, for he does not keep the Sabbath.” But others said, “How can a man who is a sinner do such signs?” And there was a division among them. 17 So they said again to the blind man, “What do you say about him, since he has opened your eyes?” He said, “He is a prophet.”
18 The Jews[a] did not believe that he had been blind and had received his sight, until they called the parents of the man who had received his sight 19 and asked them, “Is this your son, who you say was born blind? How then does he now see?” 20 His parents answered, “We know that this is our son and that he was born blind. 21 But how he now sees we do not know, nor do we know who opened his eyes. Ask him; he is of age. He will speak for himself.” 22 (His parents said these things because they feared the Jews, for the Jews had already agreed that if anyone should confess Jesus[b] to be Christ, he was to be put out of the synagogue.) 23 Therefore his parents said, “He is of age; ask him.”
24 So for the second time they called the man who had been blind and said to him, “Give glory to God. We know that this man is a sinner.” 25 He answered, “Whether he is a sinner I do not know. One thing I do know, that though I was blind, now I see.”
