Only the saints go into eternity, and go bodily after resurrection at the second coming. The wicked are slain at that time and stay in the ground dead until after the 1000 years while the saints are in heaven. Satan is alone on earth for the 1000 years (bound in the pit). All else are dead. God returns to earth after the millennium in the new jerusalem with the saints. The wicked are raised in the resurrection of the damned. Their judgement will be reveiwed by the saints during the 1000 years when the books will be opened, so we know why loved ones are not there. The wicked resurrected surround new jerusalem and are destroyed in hellfire along with the old earth and all sin including Satan. God creates a new earth.
