The Question of Morality

I have given this a little bit of thought, no a lot, but a little. Here is what the real difference between Christian Morality and Secular Morality in stark contrast.

Lets assume for a moment that God truly reveals himself in such a way as no one can deny his existence. God has come to earth and shown beyond any reasonable doubt that he is in fact the God of the bible and he exists. He then promptly issues the following command;

“In the cities of the nations the Lord your God is giving you as an inheritance, do not leave alive anything that breathes. Completely destroy them, the Canadians, and Mexicans, as the Lord your God has commanded you.”

With no other information available, other than what I have provided, what do you do?

• The Christian response should be, "Yes master, let me go get a baseball bat and a couple of guns.".
• The Secular Humanist, Atheist if you will, should respond with; "Hold on a minute, what the fuck!, NO!"

Don't give me any bullshit about "God wouldn't do that!", the guy has a track record, he has done this in the past, since he is timeless and unchanging, there is no reason to believe he would not do it in the future. Lets be real, Revelations points to a very bad end for humanity. So the real question is, what is the truly moral thing to do here? Does faith and obedience justify the deaths of millions of people? Is defying the ultimate authority really a good idea?

My thought experiment for the day.
