If you have not seen this fabulous, 3 hour debate between Christian Apologist James White and (former? Sort of?) Jehovah’s Witness Gregg Stafford, you simply must. Hands down, the best interaction I’ve seen between these two groups so far. Well worth the time.
And for your debaters, there is much to be learned for the two different cross-examination strategies deployed here. Take lots of notes; it starts at at 1:32:27.
They get into a fiery disagreement over Revelation 4 and 5. I’m doing some work in John’s gospel right now, but if I can find the time I’ll try to get up some more information on that.
