Okay, I'll guess. It sounds like those born of the Spirit don't have a body of flesh. Is this talking about our spiritual body after we are resurrected?
That's probably dumb since why wold Nichodemus know that?
That is what the Lord Jesus Christ plainly stated. We don't know where they came from, or where they went. He likens people born of the Spirit to the wind. And that idiot that said "wind" is supposed to be "Spirit" thinks the Lord likened those of the Spirit to be like the Spirit. The problem is, the Bible does not say what people want it to say. It is typical of "Pentecostals".
The prophets spoke of it, so Nicodemus should have known. And the Lord Jesus Christ in his typical fashion mocked him for it. The Israelites used bone boxes, expecting their dry bones to live again. The bone boxes are still being found around the old city area of Jerusalem. Including Simon bar Jonah, aka Peter. He is not buried in Rome. He proselytized, as evidence from Paul's letter to the Romans when Paul offers them the Body of Christ.
