[22:01, 1/1/2019] Jacob Appiah Sarpong:
During the 1,000 years, the saints and Christ will be in heaven, 1Thess 4:14-18 (14. For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. 15. For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. 16. For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17. Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18. Wherefore comfort one another with these words.).
This will be the beginning of heavenly journey. With this, we know that during the 1,000 years popularly referred to as the millennium, Christ reigns with His saints IN HEAVEN not on earth. It is after the 1,000-year period that Satan would be loosed out of his prison on earth and goes to deceive the resurrected wicked people who did not deserve to go to heaven with Christ at His 2nd coming, to take over the Holy City when fire from God devoured them to suffer the 2nd death. Events in Rev 20 clearly show heavenly scenes of Christ and His saints actually reigning and to whom judgement was given v4. It is after the 1,000 years and the completion of the judgement by the saints that Satan and the wicked destroyed.
