I'll leave the "godspeed" discussion up to you guys... I have but one thing to say about the JW's (well, two things):
1. If we spent half as much time developing and adopting the systematic approach to witnessing they did, and then actually implemented it, we'd be a lot further along as a body than we are. Furthermore, half of the JWs would probably be Christians if we were about our Father's business (the way they are) instead of our own.
2. Has anyone noticed that there's only ONE denomination of Jehovah's Witnesses? One organization. They don't have the 7th Day JWs, the JW Hall of Jehovah, the Apostolic JWs, the JW Baptist Hall, JW Methodist Hall, JW United Methodist Hall, and all that... they are ONE body of believers. They are united. They all teach, believe, talk, and do the same thing. They are consistent. Pose any question and you'll get the same answer from any of them anywhere in the world. They are on one accord.
So say what you wanna, but they're doing something right, even if it's for the wrong cause. Right or wrong, we can definitely learn something from them.
