John 3:3 "I tell you the truth, no one can see the kingdom of God unless he is born again."
Rebirth is not resurrection. Rebirth is to repent to God’s satisfaction, and meet the conditions of entering the blissful heaven, and restore the spiritual body, so that after death, one can can go to the blissful heaven and enter eternal life. Rebirth doesn’t occur after death, but occurs when one is alive.
