The Rapture is a word to which some critics object because they say it isn’t in the Bible. In fact, it is in the Latin translation of 1 Thessalonians:4:17. The Latin rapturos means an ecstatic catching away, as does our English word. In any language, that is exactly what the Bible declares will occur when Christ returns to take His own to His Father’s house of many mansions. Such was our Lord’s promise, and He will not fail to keep it.
The hope of the Rapture is a teaching which is unique to Christianity. On that basis alone, it is a far more important doctrine than most Christians acknowledge. For anything that lessens Christianity’s uniqueness weakens its foundation and increases the danger of confusion and compromise.
