It is still him or her who will go to Heaven or not.
How God changes our flesh, does not change what we are.
A evil person after death is still evil.
Yes, ' chosen ' males or females go to heaven, but the majority of mankind will remain here on earth. You're right, death does Not change who we are at the time of death.
Those who are resurrected to heaven are classed as saints or holy ones.
As Romans 6 vs7,23 mentions: the dead are freed or acquitted from their sins.
So, except for those committing the unforgivable sin - Matt 12:32; Hebrews 6: vs 4 to 6 - the rest will have a resurrection - see Acts 24:15 - because both the righteous and unrighteous will be resurrected. Those judged as evil or wicked will be destroyed forever - Psalm 92:7
Being freed or acquitted from sin - Romans 6:7 - does Not mean now innocent, but as a governor can pardon a person so the crime charges No longer stick, Jesus can pardon a person so the sin charges No longer stick. This opens up the door, so to speak, for the possibility of total compassion on the part of Christ taking place during his 1000-year kingdom rule over earth when there will be a healthy physical resurrection of the dead who will be restored back to life on a paradisaic earth with the possibility of living forever on earth. -Psalm 37:11,29
