John 9:35-39

When Jesus heard what had happened, he found the man and asked, “Do you believe in the Son of Man?” The man answered, “Who is he, sir? I want to believe in him.” “You have seen him,” Jesus said, “and he is speaking to you!” “Yes, Lord, I believe!” the man said. And he worshiped Jesus. Then Jesus told him, “I entered this world to render judgment—to give sight to the blind and to show those who think they see that they are blind.”
