I loved this article  by Steve Camp.  It's plenty long, but SO good.  If you disagree with the fact that we are totally depraved and unable to choose Christ, you may disagree with the premis that we can't insist that the world (still in it's oblivious to sin state) hold to our moral compass.  Not that anyone is saying we should ignore sin or not call it what it is, but what good does boycotting Walmart do?  Sure, they are very pro gay rights, along with a whole host of other things that doesn't line up with biblical principles.  Who says they are supposed to conform to what the bible says is right?  They are the world..... we aren't to conform to them, no one said anything about them supposed to conform to us.  If it makes you feel better, boycott them, but insisting that ALL christians should avoid Walmart because they are evil.... well, can't say I can agree.  Stand up and say sin is sin... Be holy because God is holy.  Don't listen to Madonna because she preaches filth, understand that Oprah is dead wrong about everything.  But don't expect the world to follow your lead.  We, who are bought and paid for by the blood of Christ alone, for the Glory of God alone,  are the strangers and aliens in this land.
