Note what the Reasoning book said about the Rapture in 1984:
Rapture
Definition: The belief that faithful Christians will be bodily caught up from the earth, suddenly taken out of the world, to be united with the Lord “in the air.” The word “rapture” is understood by some persons, but not by all, to be the meaning of 1 Thessalonians 4:17. The word “rapture” does not occur in the inspired Scriptures...
Will all faithful Christians be taken miraculously from the earth by the Lord before the great tribulation? Matt. 24:21, 22: “Then there will be great tribulation such as has not occurred since the world’s beginning until now, no, nor will occur again. In fact, unless those days were cut short, no flesh would be saved; but on account of the chosen ones those days will be cut short.” (This does not say that “the chosen ones” will all have been taken to heaven before the great tribulation, does it? Rather, it holds out the prospect to them, along with associates in the flesh, of surviving that great tribulation on earth.)
The latest WT articles say, the ones that have so far caused such a stir among us: All faithful anointed ones who are still on earth after the initial part of the great tribulation has passed will already have received their final sealing. Then, as indicated in Jesus’ prophecy about the great tribulation, they will be gathered to heaven. I rest my case!
