The New Heavens and the New Earth - Are We Expecting a New Creation?

Is there a dismantling of racial, economic and even gender differences? If yes, it seems to lend credence to the idea that everything will be new. When jesus speaks of resurrection reality, he says that they nei marry nor are given in marriage, but are like angels in heaven. So anything we can say about these things now? Or do we simply not know? Well, great question. It obviously relates tangentially to one verse in galatians, galatians three 28, neither jue nor greek slave nor free know male and female. But its obviously much, much wider. Will there be gender related relationships in the new creation? We simply don't know
