I do wish I could find a Christian who has read the Bible enough to know that on death all thoughts perish - and therefore a dead person cannot know, feel or experience anything!
All of history's dead are still in their graves and will stay there until Jesus and his angel army arrive at the height of Armageddon, Then he will resurrect 144,000 true Christians to help him govern Earth during the 1000 year millennium.
After the millennium Satan and his two gangs of fallen angels will be released from the pit inside Earth and allowed to travel earth trying to recruit new followers. This is shown in the pope's throne. Any new followers will be the tares who despite living with Jesus for 1000 years still harbour the possibility of being sinners. Some tares will join Satan but just when he is gloating he will be seized and tossed in the lake of fire while all his angel gangs, the demons of the Nephilim and the tares will be totally annihilated.
This is what the Bible says but I've yet to meet a minister who preaches it!
