Even so, the apostle John seems to close the gap on that, especially in Revelation.
Yeah, but even within Christianity, certainly within the Anglican communion, there's a lot of questions over some of the assumptions present in just that short sentence. I doubt it would even occur to you to question them. That's fundamentally going to be the gulf between your interpretation of scripture and JWs' too. It would be the same sort of response as if you tried to explain Yahweh being Jesus to a Gnostic. They'd think you were slightly dotty and terribly deluded. And vice versa. :) How it goes, isn't it?
