There will be the first resurrection and those who did not take the mark of the beast and were beheaded, get to reign with Christ a thousand years and be priests. Then after the thousand years are up, Death and Hell give up the dead in them and thrown into the lake of fire. Then judgement from the book of life.
The man of Sin, son of perdition must be revealed first before the Gathering together unto Christ (Rapture) 2 Thessalonians 2:1-4. The Antichrist comes first to exalt himself above God, to blaspheme God and to do signs and wonders to deceive people on earth, causing fire to fall from the sky. Then Jesus comes back in the clouds. The days will be shortened lest no flesh would be saved.
