*** You Can live Forever (1982, 1990) p.255 ***
Do not conclude that there are different roads, or ways, that you can follow to gain life in God's new system. There is only one. There was just one ark that survived the Flood, not a number of boats. And there will be only one organization—God's visible organization — that will survive the fast-approaching "great tribulation." It is simply not true that all religions lead to the same goal... You must be part of Jehovah's organization, doing God's will, in order to receive his blessing of everlasting life...
The above is vague for sure, but this one is a LITTLE more clear with things. This was the closest I found Elsewhere. (thanks to blondie here)
Jehovah uses this organization because it is meek and teachable and is not set and bound in its viewpoints. It is an organization that looks to Jehovah for guidance and direction and watches his maneuvering of matters on the world scene and the outworking of events that fulfill prophecy and it lines up its views in accord with these things. It is willing to change and keep up with the developing conditions, to keep up with the light as the light is revealed brighter and brighter. That is why Jehovah can use this organization, and certainly the facts show that he has been using it and is continuing to use it. He is bringing the increase. He is using this organization to preach the good news of the established Kingdom in all the inhabited earth. Prophecies are being fulfilled upon this group. We are counseled to remain close to the organization, for even if the organization does have views that are later changed, our safety lies in remaining within the organization and changing with it when the light increases and new truths are discerned.
No other organization has shown this flexibility to alter its views, to keep up with the changing times, to be alert to the increased light that comes from Jehovah from the temple, for other groups are bound by their centuries-old creeds. Rather than a stumbling stone, the Society's readiness to alter its views when necessary should be a source of comfort and encouragement, an assurance that there will be continual advancement and increase in learning, an ever-brightening light as we approach closer to the perfect day with its noonday brightness. A false religion may have some truth in it, but it never gets rid of its many falsehoods and the truth it does have continues to be contaminated. With Jehovah's organization the beliefs can be established from the Bible, and when some erroneous view does creep in it is soon ferreted out and discarded.
