are you really trying to say the bible(as that where all Christianities teachings come from) original teachings were unity and peace?? you cannot be serious
Deuteronomy
God really lays down the law in Deuteronomy. And he insists that you follow it, exactly as written without adding to or subtracting from it. The law applies to everyone for all time. No excuses. (See
28:15-68 for a list of things God will do to you if you refuse to obey.)
Of course the first thing you'll have to do is kill people. Lots and lots of people.
Revelation
Everything in Revelation should probably be highlighted, because it's all violent, cruel, or absurd in one way or another. But that would make it too hard to read, and it's hard enough as it is.
Revelation has my vote for the worst book in the Bible. And since the Bible, Quran, and the Book of Mormon are the three worst books ever written, that's saying something.
