*** w55 10/15 p. 624 par. 9 The Triumphant Message of “The Kingdom” ***
The missionaries of Christendom throughout the earth number into the thousands. Despite all these, it is not too much to say that Jehovah’s witnesses are the only ones preaching “this good news of the kingdom.” Why? Because they are the only ones that see the established kingdom in the light of modern events interpreted by Bible prophecy, and they are the only ones with the faith and courage from God to preach it.
There cannot be a more exclusive claim than this. Indeed, Jehovah's Witnesses (over 6 million worldwide in a concerted effort) are preaching "The Kingdom" and "Bible prophecy." Of course, many in "Christendom" would proclaim a similar message. But The Watchtower is very clear in their exclusive distinction:
*** w81 5/1 p. 17 par. 3 If God Has an Organization, What Is It? ***
Let the honest-hearted person compare the kind of preaching of the gospel of the Kingdom done by the religious systems of Christendom during all the centuries with that done by Jehovah’s Witnesses since the end of World War I in 1918. They are not one and the same kind. That of Jehovah’s Witnesses is really “gospel,” or “good news,” as of God’s heavenly kingdom that was established by the enthronement of his Son Jesus Christ at the end of the Gentile Times in 1914. (Luke 21:24)
Though the Society will admit that there are missionaries in Christendom that "preach," they place themselves in stark contrast by the fact that they are the only ones preaching 1914 as Christ's enthronement. In light of this, they emphatically proclaim the nearness of God's judgment on babylon the great (i.e. "Christendom") and the rest of wicked mankind.
But is there even the possibility that non-Jehovah's Witnesses are preaching the gospel? According to The Watchtower:
*** w95 9/1 p. 18 par. 18 Christian Witnesses for Divine Sovereignty ***
18 The worldwide preaching of the good news helps to prove that Jesus’ royal presence has begun. (Matthew 24:3) Further, it is the main means by which “the harvest of the earth” is being reaped, as it points people to the only true hope for mankind, Jehovah’s Kingdom. (Revelation 14:15, 16) Since only genuine Christians share in the preaching of the good news, this important work helps to distinguish the true Christians from the false. (Malachi 3:18)
Since the Jehovah's Witnesses are the only ones proclaiming "the gospel of 1914," then all non-Jehovah's Witnesses are false Christians. They are nothing more than sincere messengers proclaiming a false gospel that will ultimately incur the judgment of God upon themselves and the rest who were deceived by their false gospel.
At this point, i'd like any Jehovah's Witnesses watching this to give consideration to the following video, whereby one of "Christendom's" missionaries preaches what he believes to be the "gospel" to two individuals. In doing so, please think about the following:
1. Is this a false gospel?
2. Is this a false gospel because he neglected to mention 1914?
3. Was it a false gospel because he neglected to mention how "close we are to the end?"
4. Is it a false gospel because he failed to mention that salvation can only be found in being in association with his organization?
5. Is it a false gospel because he never mentioned "Jehovah?"
6. Should he have left out all the stuff about repentance and placing faith in Jesus' atoning work in favor of proclaiming 1914 and "how close we are to the end?"
7. In one encounter, could you as a Jehovah's Witness provide the necessary information whereby one could avoid the impending judgment that could come on that very day?
8. What other approaches did this man use that were wrong and worthy of being called a "false gospel?"
If you would, please watch the following video and provide some commentary on how "Christendom" needs to abandon this message and proclaim the true gospel:
