The zombie apocalypse

We'd all be psychopaths trying to do two or more different things at once.

Keep god's laws first over man made laws, but don't forget that god commands you to honor the law of the land you live in.
Love one another, but it's totally cool to have slaves.
Let your light shine so others can see your good works, but don't show everyone you are doing good things or you'll be a hypocrite.
Turn the other cheek, but take up your sword.
Don't kill, unless god tells you to sacrifice your own child.
Don't kill, but wipe out every living person in a specific city if god says.
Don't kill, but kill those who commit adultery, but only throw the first stone if you are without sin yourself.

I don’t think that is possible unless you choose one to follow to the letter.
