Pastor Toller’s spiritual anguish, I think, is an exaggeration of a malaise that afflicts much of the church and society. It is not a lack of faith (either for Toller or the church at large). We become so overwhelmed by the griefs and pains of life that we feel paralyzed to address the deep needs of the world around us.
For Marguerite in the film, her fear and depression are overwhelming. Even the people around her and their love and attention cannot bring her out of her “slough of despond”.
Our ability to think, talk, reason, question, and make sense of the world wouldn’t exist if not for the brain. And yet, with all the scientific advancements in our technologically rich society, we still don’t know very much about it. But perhaps that is changing.
