Doug Wilson decries modern evangelical tendencies to trivialize the sacredness of the Christian faith. That books such as The Shack could ever become so influential and widespread among evangelicals says a whole lot about our failure to “take every thought captive to obey Christ” (2 Cor 10:5).
I remember one time I was at a conference where the group I was with was sharing the venue with another group. So one time I sat in on the chapel services of that other group, and they began singing “Spring Up, O Well,” which was fine with me. But since the song involved water, somebody had developed hand motions, and jumpy-up-and-down-motions. So there was this room full of adult Christians jumping up and down while they were singing, splish splashing along. But then they got to a verse where it was all about the blood of Christ instead of water, and they continued right on with the hand motions and the jumping, and the only thing missing was the rubber ducky, and nobody blasphemes like an evangelical can.
