Some Basics

What IS the Rapture? 
The Bible tells us that before the great Tribulation comes upon the earth, the Lord will remove his believers from the earth.

"For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord. Therefore comfort one another with these words."
Thessalonians 4:16-18

The source of the word "Rapture" 
In the Greek translation of the Bible, the words "caught up" are the word "harpazo," which means to sieze, catch away, pluck, pull, take by force.

When the Bible was translated into Latin in the 4th century, the Latin word used for "caught up" is raptere, "to seize, snatch, tear away." It's from "raptere" that we get the term "Rapture."

Whom Is He Coming For? 
An ominous warning here. Not everyone is taken, as is gleaned from the parable of the five wise and the five foolish virgins. That's another study. The point here is this: he's coming for those who are eagerly watching for him. More often, conversation is about who the Antichrist might be. Jesus is coming for those who are eagerly waiting for HIM, not for the Antichrist.
"To those who eagerly wait for Him He will appear a second time, apart from sin, for salvation." Hebrews 9:28

As Christians we are not to look for the Tribulation, or for the Antichrist, but for "His Son from heaven who has delivered us from the wrath to come."
Ist Thessalonians 1:10

Jesus is the pattern 
As it happened to Jesus, so will it happen to us. Those who have been conformed to his death, will also be conformed to His resurrection. Jesus is the pattern. We were shown a picture of the Rapture at the Rapture of Jesus. Are you surprised to hear that Jesus was Raptured?

"And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel, who also said, 'Men of Galilee, why do you stand gazing up into heaven? This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven.''' Acts 1:10-11
