I have been thinking about this posting on oldtruth.com. Many in the seeker movement believe that you must lure people into the church with cool music and videos and then God will work on their hearts. It is my firm conviction that many who say that to save the world the church must look like the world are well-meaning - I really do respect their desire to reach their unsaved neighbors, and indeed wish that all reformed believers were as zealous - but just as "zeal without knowledge" (Romans 10:2) is not good, I believe that many of them really do not know whereof they speak. How many of these seeker/emergent folks are anywhere from 20-somethings to 40-somethings and have spent virtually their entire lives in the church? I think that most (not 100%, but I believe the vast majority) have lived in somewhat sheltered Christian communities their entire lives, and are, quite naturally, reacting against both perceived and real problems in the church.
As someone who was on the outside for my entire adult life until God sovereignly chose to save me at the age of 35, I can tell you that I would not have been taken in by worldly music, videos, and self-help sermons, nor by cussing preachers. Believe me, I knew cussing plenty well: my friends and I did enough cussing for all the cussing preachers out there put together.
While I might have been willing to attend such a worldly church - for awhile anyway, until I got bored or had something better to do on Sunday mornings - what brought me to Christ was several people who, without being judgmental of me, were different. Although on most occasions they didn't rebuke my profanity, they were always strangely silent when we were using it. I'll always remember one guy who made one single, soft-spoken remark after one particularly vile thing I said: "That's kind of gross if you think about it." He probably does not remember saying that, but 20 years later I still remember it clearly.
What converts people? The Holy Spirit working through the word of God and examples of changed lives around them. Not churches copying the world.
