Rapture comes from the Latin word, rapio, which means “a snatching away.” The Rapture, then, is the time when the Lord comes in the clouds of glory, bodily (see Acts 1:11), to take out of this world — also bodily — all those who have died in Christ and who are still living as believers in the Savior. First Thessalonians 4:16-18 describes it: 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 [the dead in Christ] in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
But your dead will live; their bodies will rise. You who dwell in the dust, wake up and shout for joy. Your dew is like the dew of the morning; the earth will give birth to her dead. Go, my people, enter your rooms and shut the doors behind you; hide yourselves for a little while until his wrath has passed by.
