“Therefore the neighbors and those who previously had seen that he was blind said, ‘Is not this he who sat and begged?’ Some said, ‘This is he.’ Others said, ‘He is like him.’ He said, ‘I am he.’ Therefore they said to him, ‘How were your eyes opened?’ He answered and said, ‘A Man called Jesus made clay and anointed my eyes and said to me, “Go to the pool of Siloam and wash.” So I went and washed, and I received sight.’ Then they said to him, ‘Where is He?’ He said, ‘I do not know.’” John 9:8-12.
“And He said to them, ‘You are from beneath; I am from above. You are of this world; I am not of this world. Therefore I said to you that you will die in your sins; for if you do not believe that I am He, you will die in your sins.’” John 8:23-24.
“I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world.” The Jews therefore quarreled among themselves, saying, ‘How can this Man give us His flesh to eat?’ Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you.” John 6:51-53.
“Therefore, when the Lord knew that the Pharisees had heard that Jesus made and baptized more disciples than John (though Jesus Himself did not baptize, but His disciples), He left Judea and departed again to Galilee. But He needed to go through Samaria.” John 4:1-4.
“Now this is the testimony of John, when the Jews sent priests and Levites from Jerusalem to ask him, ‘Who are you?’ He confessed, and did not deny, but confessed, ‘I am not the Christ.’ And they asked him, ‘What then? Are you Elijah?’ He said, ‘I am not.’ ‘Are you the Prophet?’ And he answered, ‘No.’” John 1:19-21.
