Christians, would you kill for God?

[Mudhammam]

I recently had a conversation with a Christian over the atrocious morality attributed to God in the Bible. He who told me: "Let me get something straight. I wouldn't kill anybody if I felt the inkling that maybe God wants me to kill them. That's crazy. If I literally saw God and he audibly spoke to me and proved it was him. I'd be crazy not to do what he said." While I commend his efforts as a Christian seeking to live consistently with biblical morality, I had to point out the sickening truth to this confused soul: "So you would murder someone if you thought god genuinely told you to? Well guess what? So do a LOT of people who ACTUALLY DO murder people because they think God told them."

Given that Christians don't actually believe murder is itself wrong (just read the Bible-we're all sinners deserving of death and God is entitled to instruct people to kill others) but only that whatever God tells them is wrong is actually wrong, my question is... Would you, like this other lost Christian, murder if you thought God was instructing you to do so? Would you be a "hero of faith," like Jephthah who murdered his own daughter out of commitment to the Lord? Or would you, as I have to believe I would, face God's wrath and stand up for the principle that human life is valuable and to be appreciated, and disobey God?
