Charlene, there’s a New Heaven and New Earth coming; for the first Heaven & Earth will pass away. Isaiah says we will not remember this Heaven & Earth; neither will it enter our hearts. There God will be with us, literally. Therefore, without ever remembering this Heaven & Earth neither will we ever remember this life. It will be as though we’ve been with God from everlasting to everlasting. Personally, I have no problem not ever remembering this life. It would be depressing and tearful. And you know God wipes all our tears away. He will not have pain, sorrow, regret, hate, death etc. For the former things will pass away. We will truly be His sons & daughters.
Now, I do not know if He will grant us the gender we identify with the most. But, He does give us the desires of our hearts; and with God all things are possible.
