That would be Satan who did that one Jesus didn't come to kill but the die for all of our sins on the cross. Im Christian don't turn the Bible the Word the Jesus around to make any one else the writer.
They wouldn't because Christ wouldn't do that to anyone, because Christ loves everyone. Atheists have a right to their own opinion, and if you do want to persuade anyone to look into Christianity this is certainly not the way to go about it, it makes Christians look kind of silly to be asking a question like this?
No, I would think a nut job stabbed me that also thinks he is Jesus. I would be twice as scared because now I would know that I'm up against a real crack pot.
