1Thessalonians 4:16-18 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.
‘To meet the Lord in the air.’ – Ten purposes of the rapture: To receive saints to Himself as promised (4:17; John 14:1-3; Eph. 5:27). To resurrect the dead in Christ from among the wicked dead (4:14, 16-17; Php. 3:11; Rev. 20:4-6). To take saints to heaven to live in the New Jerusalem and receive rewards (4:17; 3:13; John 14:1-3; 2Cor. 5:10; Heb. 12:22-23; Rev. 19:1-10; 21:9-10). To change bodies of saints to immortality (4:16-17; 1Cor. 15:35-58; Php. 3:21). To present saints before God (4:17; 3:13; John 14:1-3; Jude 1:24; Rev. 19:1-10). To make saints whole in body, soul, and spirit (4:16-17; 5:23; Php. 3:21). To receive the fruit of the early and latter rain (Jas. 5:7; John 14:1-3). To cause the saints to escape the tribulation of Revelation 6:1-19:21 (4:16-17; 5:9; Luke 21:36; Rev. 4:1). To remove the hinderer of lawlessness (2Thess. 2:7; Rev. 4:1). To permit the revelation of the Antichrist (2Thess. 2:7; Rev. 4:1).
‘And so shall we ever be with the Lord.’ Saints will be with Christ in heaven during the tribulation (2Thess. 2:7; Rev. 4:1); will accompany Christ to earth at Armageddon (Zech. 14:1-5; Matt. 24:29-31; 25:31-46; Jude 1:14; Rev. 19:11-21); will live in the new Jerusalem in heaven but reign on earth with Christ during the Millennium (Rev. 20:4-10; 21:9-10; Heb. 12:22-23); will move with their residence, the New Jerusalem, to the earth to live on the New Earth forever (Rev. 21:1-27; 22:1-21).
