The Jews therefore answered and said unto him, "What sign showest thou unto us, seeing that thou doest these things?"
Jesus answered and said unto them, "Destroy this temple, and in three days I will raise it up."
The Jews therefore said, "Forty and six years was this temple in building, and wilt thou raise it up in three days?"
But he spake of the temple of his body. When therefore he was raised from the dead, his disciples remembered that he spake thus; and they believed the scripture, and the word which Jesus had said.
The Visit of Nicodemus.
Now when he was in Jerusalem at the passover, during the feast, many believed on his name, beholding his signs which he did. But Jesus did not trust himself unto them, for that he knew all men, and because he needed not that any one should bear witness concerning man; for he himself knew what was in man.
Now there was a man of the Pharisees, named Nicodemus, ruler of the Jews; the same came unto him by night, and said to him, "Rabbi, we know that thou art a teacher come from God; for no one can do these signs that thou doest, except God be with him."
Jesus answered and said unto him, "Verily, verily, I say unto thee, Except one be born anew, he cannot see the kingdom of God."
Nicodemus saith unto 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?"
Jesus answered, "Verily, verily, I say unto thee, Except one be born of water and the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh: and that which is born of the Spirit is spirit. Marvel not that I said unto thee, 'Ye must be born anew.' The wind bloweth where it will, and thou hearest the voice thereof, but knowest not whence it cometh, and whither it goeth; so is every one that is born of the Spirit."
