BLOW THE TRUMPET IN ZION!

For The Lord Himself will come down from heaven with a shout of command, with the voice of the archangel and with the (blast of the) Trumpet Of God, and the dead in Christ will rise first.

Then we who are alive and remain (on earth) will simultaneously be caught up (raptured) together with them (the resurrected ones) in the clouds to meet The Lord in the air, and so we will always be with The Lord! Therefore comfort and encourage one another with these words (concerning our reunion with believers who have died).
I Thessalonians 4:16-18
