and to give relief to you that are afflicted with us, when the Lord Jesus is revealed from heaven with his mighty angels in flaming fire,
when the Lord Jesus shall be revealed from heaven with his mighty angels: The words "when...shall be revealed" (apokalupsis) refer to "manifestation, appearance" (Thayer 62-2-602). Just as Jesus ascended to Heaven and the clouds took Him out of sight of all the people, He shall likewise return in the clouds to appear before the entire universe for the final judgment (Acts 1:9-11).
