John 9:35-38 HCSB
35 Jesus heard that they had cast him out, and having found him he said, “Do you believe in the Son of Man? ” 36 He answered, “And who is he, sir, that I may believe in him? ” 37 Jesus said to him, “You have seen him, and it is he who is speaking to you. ” 38 He said, “Lord, I believe,” and he worshiped him.
The formerly blind man comes to the understanding that his healing is from the Lord. Seeing and listening to Jesus, he believed and worshipped God.
