This, then, is our Lord’s return at the end of the tribulation to harvest the bodies of the saints who die during the tribulation (Rev. 14:13+) so as to reunite them with their souls, which, up to this point, will have been under the altar before God (Rev. 6:9+). This reaping is the gathering of the harvest into Christ’s barn (Mat. 13:30). . . . The living redeemed will still be on earth, but the bodies of all deceased saints will have been resurrected and taken to Heaven. This addresses the state of all the saved during the tribulation.1The saints which remain alive at the end of the Tribulation participate in the Sheep and Goat Judgment and enter the Millennial Kingdom in their natural bodies (Mat. 25:31-34).
