Kent Brandenburg is someone that I rarely agree with. I once was a fundamentalist as he is. But I still share some concerns that they have about worldliness. I don't always agree on their specifics of what constitutes worldliness. But here he gives good reasons why not to have a Facebook account. Certainly, some of these reasons can be applied to other orbits of the Internet (I don't even believe in Powerpoint Preaching).
Facebook (and addiction to it) is pervasive in the Evangelical church. My first concern about it happened when I attended seminary. Yes, I said seminary. I noticed that scores of seminarians were addicted to it -- spending 2–5 hours a day on it. I have no idea how they managed their studies by being consumed by this social network. I never asked. But maybe I should have. That was over three years ago. I cannot imagine how more prevalent it is today. Should seminaries crack down on facebook addiction with students? Should God's people finance tens of thousands of dollars to send their young men to seminary so they can play on facebook all day and night?
I think we can have a beneficial discussion on this topic. What are your thoughts after you have read all of Kent's reasons.
