The 2007 book The Shack, by William Paul Young, and the 2017 movie based on the book, have become immensely popular. Some 20 million Americans have read the book. Many high-profile figures have endorsed the novel and movie and have given rave reviews of a story dealing with suffering and the Bible. For many, The Shack might be the only Christian-themed exposure they ever have to Christianity. Hence, it’s important to have some degree of familiarity with the message the story conveys. In this booklet, Dr. Larry Spargimino examines the theology behind The Shack.
