A good number of comments on this thread suggest that many bible versus can be safely discarded or outright ignored based on criteria such as a mass killing. I don't understand this thought process, because you would know nothing about Jesus if it were not for that book. So how can it be anything other than all or nothing?
The bible states that Jesus studied the old texts thoroughy and endorsed the principals and laws of the OT rather than rejecting any of it. So when he makes the statements:
"Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill." - Matthew 5:17
"It is easier for Heaven and Earth to pass away than for the smallest part of the letter of the law to become invalid." (Luke 16:17 NAB)
It's a leap of logic to say that he didn't mean the to include the expressions of Jeremiah, Ezekial (quoted at the outset) and others.
I get the sense from some of the comments so far from those who profess belief in the bible and Jesus, somehow doubt that he is capable of such mass slaughter, yet alone destined for such slaughter in the realm of bible lore. Yet this is what's said of him in Rev, not so warm and fuzzy.
Then I saw heaven opened, and behold, a white horse! The one sitting on it is called Faithful and True, and in righteousness he judges and makes war. 12 His eyes are like a flame of fire, and on his head are many diadems, and he has a name written that no one knows but himself. 13 He is clothed in a robe dipped in[a] blood, and the name by which he is called is The Word of God. 14 And the armies of heaven, arrayed in fine linen, white and pure, were following him on white horses. 15 From his mouth comes a sharp sword with which to strike down the nations, and he will rule them with a rod of iron. He will tread the winepress of the fury of the wrath of God the Almighty. 16 On his robe and on his thigh he has a name written, King of kings and Lord of lords. - Rev 19:11-16
Blaming humans for not warning the wicked before a mass annihilation which they have no idea of when it's coming (2,000 years and counting) is just beyond the pale of twisted, sick and evil. Furthermore, I've pondered for many years that if god were to kill all the bad people how is anyone to have confidence that it will be any better than it is now? The god of the bible's track record on new beginnings doesn't inspire any confidence. There is a reason 1/3 of the angels left and the Isrealites refused to do it his way. I think being a witness provided a taste of what the thought controlled paradise might be like.
I'm happy that many believers can still believe and be peaceful and happy despite what the immense guilt the bible ladens on. Jesus load is not light, just ponder how foolish his advice in Matt 6:33 is in practice. I tried for 30+ years and could no longer stomach it, uncertainty, ambiguity, and lack of tangible evidence, is a terrible foundation for a relasionship. Since I've stopped worrying about trying to please the ever watchful high command I have never been happier. If there is a diety out there that does requires worship from humans than it needs to do a much better job of explaining things to earn it IMO.
Lastly, regarding the point about people that don't really believe in the god of the bible not having the right to discuss these topics is nonsense. When arguing about god, the implied meaning from the non-believers side is simply the the concept of god. It's much like going into J.R. Tolkien's world and discussing the characters like Sauron (as Beks alluded to).
