1. The Jehovah's Witness religion will still be here, long after you and I are dead. A little group of Christians in 36 AD started a movement that has lasted up to our current day. Jehovah's Witnesses are not going away, not matter how much you desire them too. Voltaire said Christianity would be extinct with in one hundred years of his time. Voltaire was much smarter than either one of us, he badly underestimated people's desire for hope, and a longing for meaning in life.
2. How long is the shelf life? Naysayers thought Mormons would last no longer than a decade, Joseph Smith had a very interesting background, Brigham Young and Joseph Smith Jr, the Republican presidential candidate is a Mormon! Joseph Smith started in 1820, we are in the year 2012, Mormons are still running strong after 200 years, the Watchtower had some strange ideas (not as weird as Mormons), given the long run of the Mormon church, JWs will make it to another hundred years. Rome attempted to dismantle early Christians, trying to strike terror into Christians backfired, shelf life of Christianity, almost two thousand years now and no end in sight.
3. Most of the followers of Jesus Christ for the first three hundred years did not have a high education. Our times are cake walk compared to the economic struggles, political attacks, martyrdom endured by early Christians. JWs will get by just as well, they be enjoying a fulfilling life of wealth, we are aware of the correlation between higher education, wealth and happiness.
4. Christians for close to Two Thousand Years have been thinking the "End is near", countless Christians over this period have lived simple lives, other Christians who made it big have donated huge amounts to charity. The "End" has not come, Christendom evolved into believing Christ would reward them at death. You can hope the Organization will crumble but there are to many diehards who don't find enlightenment or comfort knowing there is no hope.
5. "We feed people for 100 years" Parts of Christendom believe they have been feeding their sheep since Pentecost, close to two thousand years. Terry you can hope the Society will crumble but history reveals groups live on past our lives. The crazy beliefs Russell and Rutherford were teaching one hundred years ago are gone, a more sanitized version now exist. The Watchtower will become more friendly as the system of things continues.
6. "Events driven" religions like the Society will add people when wars, chaos, masscres take place. Chaos, massacres, injustice is good business for the church, atheism won't plug the emotional bleeding our Americans are feeling in Colorado. I can't imagine myself telling a victim of this tragic event something like "your child is gone forever, you won't see them again!" the killer robbed them of their child, and we can give them hope or rob them of it. If you were to deliver a funeral talk for one of the victims, the talk being for the living, how would you word it?
