Hey PG, checked out your video......good job on it and being open enough to allow him to express his feelings and thoughts without judgement (something he said christianity was plagued with "more than any other group")
Not to be judgmental

but I noticed he liked to talk about how much personal studying he has done but when he used the scripture of "judge not lest ye be judged", he misapplied it.

And as far as christianity being hypocritical, has he paid attention to how intolerant most far left liberals are when it comes to anyone who disagrees with there positions?
Another point, he said he didn't like being "preached to". In my experience that ideology is usually held by people who don't want to be made to feel guilty over the choices and behaviors they adhere to. I mean i can't count the times that I have been in church and the pastor preaches on something that hits close to home. Like the times when I would be struggling with various thorns in my side and the message would be about those very things! Now I could have focused on how uncomfortable that made me feel or I could have used those messages to reevaluate my life and behaviors and used them as a means that that is how the Lord was communicating with me through the message. Rather than get all puffed up and think "how dare they preach on this and judge me", I looked at it a different way and became humbled by this revelation and tried to change my actions to be more biblically centered.
Many times, perhaps even subconsciously, our flesh is looking for a reason to defy the Spirit. If our ears can be tickled in such a way that we feel the church is against us then our flesh will jump on it and use it as a point of contention with the spirit.
This is what I think happened with this man and his connection to his music. The pastor cast a bad light on something he held dear, in this case his metallica music. Basically he, like the rich young ruler, couldn't part with something he desired (his love of the band) to be more committed to Christ. That pastor could have been dead wrong about his connection of the band and that particular song to being satanic....(I don't think he was but thats another topic)....but that really isn't the issue. The issue is that he wasn't able to accept the fact that sometimes he is required by the will of God to deny himself and his personal desires to favor of the will of God.
As a side note, I don't buy for a second that Metallica isn't a band of anti- christianity or anti-religion. If anyone has done any serious inquiry into many metal bands (and other genres) it is clear of there message of how they view organized religion (including christianity) and how they view it as oppressive and controlling. What this man has done was ignore the fact that the bands message is one of independence of religious observance and rather than reject the bands message he fell for it and left the faith. sad.
