What JWs don't want you to know prior to joining

Watchtower, the alleged and self appointed representative of God (they call him Jehovah) preach that salvation is reserved exclusively for its Jehovah's Witness members. A vital part of of being a Jehovah's Witness it be to part of the Watchtower organization as the only one recognized by God that can provide them with protection from destruction - of course claimed by Watchtower.

Here are some extracts from Watchtower that make their self proclaimed stand clear.

"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." Watchtower 1989 Sep 1 p.19
"Similarly, Jehovah is using only one organization today to accomplish his will. To receive everlasting life in the earthly Paradise we must identify that organization and serve God as part of it." Watchtower 1983 Feb 15 p.12
"Is it presumptuous of Jehovah's Witnesses to point out that they alone have God's backing?

Watchtower 2001 Jun 1 p.16

(2 Peter 2:5) In these last days of the present system of things, Jehovah's people are making known Gods righteous standards and are declaring good news about the possibility of surviving into the new world. (2 Peter 3:9-13) Just as Noah and his God-fearing family were preserved in the ark, survival of individuals today depends on their faith and their loyal association with the earthly part of Jehovah's universal organization." Watchtower 2006 May 15 p.22 "Are You Prepared for Survival?"

You are unlikely to hear this straight from a Jehovah's Witness as they appear to get some rather severe stage fright when confronted with these Watchtower publications but never distance themselves from these claims either. Where possible they will ignore you or change the subject when the issue is raised. The reality of the position will become clear after you become a member.
