The timeline I'm talking about has the tribulation first. People are alive and there are people being killed and martyred. It is 7 years long. This is not when the wrath of God comes...that comes after Jesus returns and the 1000 yrs reign begins. The war of Gog and Magog has not happened yet. That comes before the wrath of God, which is the end because the "valley of decision" is upon them. A new heaven and a new earth is then formed.
During the 1000 yrs, people will be eating, drinking and marrying and having children all during this time. They will learn the truth of Jesus without satan being around to interfere and after the 1000 yrs are finished, satan will be released to go out and deceive the nations again. These are the people that now must serve God or serve satan for the end is soon coming.
