It's got nothing to do with whether they are Jehovah's witnesses or not. We aren't judged by what we believe. We aren't judged by the doctrines we subscribe to. We are judged by our works. And I could cite numerous passages of scripture which inform us clearly as to what works are acceptable and what aren't. The description of the last judgement in Matthew 21:31 on, is but one such example.
That isn't too say that doctrine and belief aren't important. But never underestimate the love and power of God in converting anyone... Even Jehovah witnesses, Mormons, wow, Even me and you.
are you saved by your works?
