we (JWs) are the ONLY ones who obey Christ's command to preach the Good News of God's Kingdom, and worship his God & Father!
LOL ! First of all Martian, what's this "WE" business? Second of all, JWs are incredibly naive about the act of "preaching". Preaching is not merely the act of door-to-door canvassing and placing literature. It encompasses so many different ways. The church I attend has many different ministries in which it performs. They go into hopspitals, orphanages, and prisons. Oh, and guess what. People do it out of pure desire; not out of compulsion for turning in time. They also perform charatble acts for people, as described in the book of James. You have read the book of James haven't you?
Also, I would suggest you go to a library and check out some books on Christian history. There were missionaries and Bible study groups in places like China long before the Watchtower Society even came onto the scene. Missionaries were translating Bibles into African dialects before C.T. Russell was even born.
You may want to read the book of Galatians where Paul warns people not to follow new Gospels. When an organization preaches that salvation can only be attained through an organizational membership, that Jesus is mediator to only 144,000, and that people must accept a huge sectarian doctrinal package before they can undergo Christian baptims, they are guilty of preaching a new Gospel. But I guess we are supposed to be impressed by the fact that JWs go door-to-door and pass out Awake articles on Kangaroos and pineapple growing.
