Nicodemus said to Him, "How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?"

Nicodemus answered and said to Him, "How can these things be?"

The Jews then complained about Him, because He said, "I am the bread which came down from heaven."

The Jews therefore quarreled among themselves, saying, "How can this [Man] give us [His] flesh to eat?"

Therefore many of His disciples, when they heard [this,] said, "This is a hard saying; who can understand it?"

The people answered Him, "We have heard from the law that the Christ remains forever; and how [can] You say, 'The Son of Man must be lifted up'? Who is this Son of Man?"

Then [some] of His disciples said among themselves, "What is this that He says to us, 'A little while, and you will not see Me; and again a little while, and you will see Me'; and, 'because I go to the Father'?"

They said therefore, "What is this that He says, 'A little while'? We do not know what He is saying."

"You will seek Me and not find [Me,] and where I am you cannot come."

But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know [them,] because they are spiritually discerned.
