Can you include supporting verses please?
Then where did the idea of Christianity come from, wouldn't it still be Judaism? If Jesus just taught the same basic Jewish laws that everyone else was doing for the past 6,000+ years, then why was he so special? If you could just keep the same Jewish laws and be saved, then why did they get all pissed off and kill him? What was the significance of his death according to the text?
Nonsense. Both good and bad things happen in the name of God, and both good and bad things happen that have nothing to do with God.
What is the good of man if it's not defined by the worst of man?
Good is often defined by that which mitigates the bad.
For example, a man sacrificing his life by shielding a child from a bullet. Is it really a "good" thing that a man had to die in order to protect a child?
