I enjoyed reading these. http://mrabear.blogspot.com/ and its comments. Brian, what I like most is how you are able to fight both sides. Its pretty incredible how you challenge the Christian.
I would disagree with the issue on black and white, I think that things are a lot more black and white than we would like to think. I agree with you Brian that Christians are prone to postmodern relativism in the name of Love and not hurting other peoples feelings.
Also, the issue with being led by the Holy Spirit is this; how do we know that the spirit that is leading us is Holy and not Demonic, Selfish, Pleasure seeking, etc; at times Demonic spirits, selfish spirits, can seem very Godly? The answer is in scripture. Paul tells us to test all spirits according to scripture. We never can have any assurance that the Holy Spirit is leading us apart from scripture.
Our current Christian culture is not about glorifying God anymore. Instead it has become a therapeutic prosperity doctrine. Here is what I mean; we present Christ as a way to improve your income, your marriage, your depression, your parenting, etc. So in the end Christ is just a means to something greater rather than Christ being the one who is Great. The bible calls that idolatry. We make comments like, "we need to defend ourselves; stick up for ourselves; we deserve the opportunity to do that, have that, want that; we shouldn't be a doormat." However the one we serve was a doormat; he was a despised, homeless, poor, virgin, who was beaten and killed but yet didn't defend himself at all. That's the Jesus who we serve, that's the Jesus who we worship.
Lets remember this: "JESUS IS THE PRIZE AND NOT THE MEANS TO THE PRIZE. HE IS MOST GLORIFIED WHEN WE ARE MOST SATISFIED IN HIM. "
