I don't know about disappointed...he sound more bemused to me. Going to a church no more makes you a Christian than going to a garage makes you an automobile. Christianity, like "choice", is a verb.
I consider myself fairly literary and sophisticated, and I can't make out what this article is trying to say. Look at it one way, the author mocks a personal decision to follow Christ. Put another way, he seems to be presenting the view that his faith superiors would look at this attempt to kindle the Spirit in a youth as some kind of "cult programming". (Visit the webpage for the cartoon illustration of a small boy held upside down by a weightlifter.)
Seems to me that whatever means God wants to use to reach into the heart of a young man and tell him he needs to decide for himself if he wants to follow Jesus Christ would be viewed as a good thing. Well, based on the Biblical command to be "either cold or hot" in your Christian faith.
I should have included, “God has no grandchildren.” Every generation makes it’s own decision as to walk into the open arms of Jesus Christ, or walk the other way. As a parent, the author cannot make his son a Christian. His son has to do that, and I would have congratulated him wholeheartedly about his decision as to where he wants his life to go than condesendlingly chuckle it off. But I guess that kind of firm and encouraging story wouldn’t get published on a big website with colorful pictures of a cute little boy hanging upside down from a scary looking weightlifter.
