In his book unChristian, David Kinnaman states that "We are learning that one of the primary reasons that ministry to teenagers fails to produce a lasting faith is because they are not being taught to think."
This was a major failing of my church upbringing. For teenagers, thinking was discouraged like the plague. The lack of commitment to thinking, I think (there's that word again) went along with the path to salvation, the one that went like this: Confess, repent, accept Jesus/get baptized, livetheChristianlife.
This livetheChristianlife concept was the reason I loved Steve Taylor's "I Want to Be a Clone" so much.
"I've learned enough to stay afloat/But not so much I rock the boat"
The idea was that too much thinking would upset the faith altogether.
I figure that our God, who CREATED us, can withstand some critical thought. I once told a teenager who had some doubts that his God wasn't big enough. Our God *is* big enough, and if we can really, really think, it can help us find more and more gems in scripture.
This isn't to say that a simply intellectual approach is all that is needed. But it cannot be ignored.
