Born again does not mean being acceptable to Christ as a Christian. The term Christian was first used to mean any person who follows Christ. Certainly those in the New World, on earth, will follow Christ. When Christ spoke about born again he used a metaphor, the wind. And Christ said that people don’t know where the wind comes from or where it goes. He said that because the wind is invisible. He used that metaphor because he was implying that born again people will have another type of body that can go where humans cannot, into the invisible dimensions he called heaven. And people on earth would not see where they went.
Paul said baptism in Holy Spirit was only a token (sign), like a partial payment, of what was to come-see 2 Corinthians 1: 21,22 and Ephesians 4:30. Being born again with a body that can travel to the dimensions of heaven is what Paul meant by what was to come, in “the day of redemption.” Being baptized in Holy Spirit means a person is chosen by God. But being born again means those people actually receive those special bodies-per Christ’s words to Nicodemus.
Another thing I think JWs get wrong is saying (what they call) spiritual bodies are not material in nature. How would they know that? Scriptures don’t claim it. Scriptures state those bodies have substance. Those bodies might be made of elements mankind is not aware of. There is no way to tell what they are made of this side of heaven.
Christ’s Words
John chapter 3 :
3Jesus replied, “Truly, truly, I tell you, no one can see the kingdom of God unless he is born again.a”
4“How can a man be born when he is old?” Nicodemus asked. “Can he enter his mother’s womb a second time to be born?”
5Jesus answered, “Truly, truly, I tell you, no one can enter the kingdom of God unless he is born of water and the Spirit. 6Flesh is born of flesh, but spirit is born of the Spirit. 7Do not be amazed that I said, ‘Youb must be born again.’ 8The wind blows where it wishes. You hear its sound, but you do not know where it comes from or where it is going. So it is with everyone born of the Spirit.”
9“How can this be?” Nicodemus asked.
10“You are Israel’s teacher,” said Jesus, “and you do not understand these things? 11Truly, truly, I tell you, we speak of what we know, and we testify to what we have seen, and yet you people do not accept our testimony.
12If I have told you about earthly things and you do not believe, how will you believe if I tell you about heavenly things?
