"From a human standpoint, we will never say that we have the right religion or that someone else has it, but we will go to the Bible, share what the Bible has to say and we'll leave it up to the individual to determine who has the truth."
Let me help a brother here. Quotes taken from jwfacts.com:
"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? Actually, no more so than when the Israelites in Egypt claimed to have God's backing in spite of the Egyptians' belief, or when the first-century Christians claimed to have God's backing to the exclusion of Jewish religionists." Watchtower 2001 Jun 1 p.16
"There are billions of people who do not know Jehovah. Many of them in ignorance practice things that God's Word shows to be wicked. If they persist in this course, they will be among those who perish during the great tribulation." Watchtower 1993 Oct 1 p.19
