In the book, Burning Down The Shack, James De Young gives a startling revelation regarding the theological moorings of Paul Young, author of The Shack.
In April of 2004 De Young attended a Christian think tank and there Young presented a 103-page paper which presented a defense of universal reconciliation, a Christian form of universalism—the view that at some point every person will come to a right relationship with God. If they do not do this before they die, God will use the fires of hell to purge away any unbelief (notice the issue is not our personal sin but our unbelief). Eventually even Satan and his fallen angels will be purged of sin and all of creation will be fully and finally restored. This is to say that after death there is a second chance, and more than that, a complete inevitability, that all people will eventually repent and come to full relationship with God. De Young believes that Young’s belief in universal reconciliation is absolutely crucial to anyone who would truly wish to understand The Shack.
