After the conclusion of the Great Tribulation, Jesus will return with the saints to reign on the earth for one thousand years.
Meanwhile, during the Tribulation, there are things going on in Heaven. The saints will go before the judgment seat of Christ, where our works will be judged. Next is the marriage supper of the Lamb. This will be a celebration, not because we are skipping the Tribulation, but because we are in the presence of the Lord.
Finally, we will be preparing for war. As part of the armies of heaven, we are going to be training and preparing to return with Him and establishing the Millennial reign.
