Jesus Christ said,

"I tell you the truth, no one can see the kingdom of God unless he is born again. (John 3:3).

Nicodemus asked, "How can a man be born when he is old?"

"Surely he cannot enter a second time into his mother's womb to be born!" (John 3:4).

Jesus answered, "I tell you the truth, no one can enter the kingdom of God unless he is born of water and the Spirit. (John 3:5).

Jesus said, You should not be surprised at my saying,

'You must be born again.' (John 3:7).
