Which annotated Bible do you use?
judging
Since both Jude ('Show mercy to those who doubt') and Jesus disagree, I'm strongly inclined to chalk 2 John 2 up to human fallibility. The direct teachings of Jesus are obviously pretty important to Christianity.
conversion
Sure they would, but it's not like they can force me to believe. They'd only make me miserable.
conversion 2
I'd probably go with living as I always do, which is pretty closely in line with the Bible and involves no human sacrifice, in order to demonstrate that I can be happy, healthy, and completely un-struck-down despite not making daily blood offerings. I am not a great people person though, which means that that wouldn't really be part of my expected task in the church.
miracles
I have heard stories from close friends about miraculous healings, including one that completely nonplussed the doctors, if that helps. I tend to be conflicted about those stories though, because on the one hand I've never known these friends to lie, but on the other I've never read any reliable news reports on this kind of thing. Maybe people wave it off as sensationalist trash if they want to report it? No real idea.
Re: reproducibility, it seems to me that if there was anyone with as much power in the Spirit as Moses kicking around, they would be blowing scientists' minds left and right, but no-one has had that kind of faith in reliably recorded history.
fighting
Jesus is directly quoting Micah, a prophet who spoke about the end times. This is presumably because his arrival was the first step in the coming of the end, although by no means the last.
The upbraiding of the cities is in reference to the majority of the people inside not believing Jesus, at which he was understandably pissed. This kind of relates to the earlier quote about Moses; people can be really dumb. Oobviously, if someone has heard about Jesus and chosen to ignore him then they are going to be uncomfortable on judgment day.
Also, I agree that a religion with no teachings would be easy to follow. It would also essentially be meaningless.
