The word rapture does not occur in the Bible. The term comes from a Latin word meaning “a carrying off, a transport, or a snatching away.” The concept of the “carrying off” or the rapture of the church is clearly taught in Scripture.
The rapture of the church is the event in which God “snatches away” all believers from the earth in order to make way for His righteous judgment to be poured out on the earth during the tribulation period. The rapture is described primarily in 1 Thessalonians 4:13–18 and 1 Corinthians 15:50–54. God will resurrect all believers who have died, give them glorified bodies (no blood) , and take them from the earth, along with all living believers, who will also be given glorified bodies at that time.
“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.” 1 Thessalonians 4:16–17
The rapture will involve an instantaneous transformation of our bodies to fit us for eternity. “Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.” 1 John 3:2. The rapture is to be distinguished from the second coming.
At the rapture, the Lord comes “in the clouds” to meet us “in the air” (1 Thessalonians 4:17). At the second coming, the Lord descends all the way to the earth to stand on the Mount of Olives, resulting in a great earthquake followed by a defeat of God’s enemies (Zechariah 14:3–4).
The doctrine of the rapture was not taught in the Old Testament, which is why Paul calls it a “mystery” now revealed: “Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.” 1 Corinthians 15:51–52
