I have just left the org. after 26 years. I would like to make the point that the reason it is hard to leave the org. is because there have been good and faithful slaves mixed with the "evil" slave. For instance, Russell did not want an organization that is ordering you what to believe and how to dress, etc. He was given truths from the bible that the other religions honestly don't have. Such as that Jesus isn't God, no hellfire, no immortality of the soul, no priests, no man to be called father, the ransom, the paradise earth, kingdom being a government, etc. The other religions are really in darkness as to doctrinal issues. So in comparison, JW's seems to be the true religion. Also I believe Ray Franz and some of the others that got disfellowshipped were faithful slaves. But with the wheat growing in among the weeds, it's hard for your wife to understand that the org. is evil now. Like this scripture...
Math. 24:48 But if ever that evil slave should say in his heart, My master is delaying, and should start to beat his fellow slaves and should eat and drink with the confirmed drunkards, the master of that slave will come on a day that he does not expect and in an hour that he does not know. etc.
Maybe you could approach your wife with the angle that the organization does have truths that no other religion comes close but like all good things, man corrupts it because of their need for power. What do you think???
