I also found an interesting statement made in the Watchtower of September !st, 1989 page 19 paragraph 7 and it says,
7 Only Jehovah?s Witnesses, those of the anointed remnant and the "great crowd," as a united organization under the protection of the Supreme Organizer, have any Scriptural hope of surviving the impending end of this doomed system dominated by Satan the Devil. (Revelation 7:9-17; 2 Corinthians 4:4) They will make up the "flesh" that Jesus Christ said would be saved through the worst tribulation of all human history. As it was in the days of Noah, said Jesus, so it would be in the day when He would be revealed. Inside the ark that took many years of organized effort to complete, only eight human souls survived the global Deluge. They survived as a united family group. (Matthew 24:22, 37-39; Luke 17:26-30) Noah?s wife corresponds to the bride of Christ, and his sons and daughters-in-law to Jesus? present-day "other sheep," who have grown into an increasing great crowd, the final proportions of which we do not now know. (John 10:16) For survival into the Millennium under the Greater Noah, Jesus Christ, they have to remain organized with the anointed remnant, "the chosen ones" on account of whom the days of the "great tribulation" will be cut short.?Matthew 24:21, 22.
hope this also assists you.
