John 7:36

Nicodemus answered and said unto him, How can these things be?

Ye shall seek me, and shall not find me: and where I am, thither ye cannot come.

Many therefore of his disciples, when they had heard this, said, This is an hard saying; who can hear it?

Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother’s womb, and be born?

The Jews therefore strove among themselves, saying, How can this man give us his flesh to eat?

The Jews then murmured at him, because he said, I am the bread which came down from heaven.

The people answered him, We have heard out of the law that Christ abideth for ever: and how sayest thou, The Son of man must be lifted up? who is this Son of man?

But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
