“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: 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. Wherefore comfort one another with these words.” 1 Thess. 4:16-18.
First heard is the Lord’s shout of victory, then the voice of the archangel, which is the authority of heaven, then the trump of God, which raises the dead. This is the first part of the first resurrection.
Following the rapture will be the judgment seat of Christ for all of the heavenly saints, including all believers who have died from the beginning of the world as well as the living who will have been raptured. How blessed and happy will be this time when rewards are given.
