In the past two years I've attended two meetings and one convention. This does not mean I see the Witness organization as 'truth.' But since I've chosen to pursue their history, I have some need to stay current. I associated for some years with Church of God - General Conference [Atlanta]. We parted company amiably. They're Socinian. I am not. But there are many within Abrahamic Faith bodies such as CoGGC that are good people and as true a Christian as anyone else.
I let Witnesses in whenever they call, feeding them cookies or cake and coffee or tea. I listen politely, debate respectfully. If you're asking me what I think of Witnesses, I believe many are fine people, harmless, zealous for what they believe. Do I think the Watchtower is God directed? While I cannot say God does not direct some Witnesses, I do not believe that there is any sort of evidence that the Watchtower is his organization.
I would not discourage anyone from examining Watchtower belief. For some, being a Witness at least keeps them out of trouble. But do I see it as rational, biblical, and God's own? No.
