I do not recommend this book.
It reeks of sensationalism, not of revelation. It upholds biblical truths, but also introduces many unnecessarily gory expositions, that will entice gasps and ensure book sales, but not necessarily bring people closer to God. In fact, I have seen some fall into terror and disgust thanks to this book, rather than repentance, faith, and love for God.
I bought this book because it was recommended by someone that had supernatural and demonic experiences and testimony with psychedelic drugs. I myself had experiences like that, so I had interest in listening what others had to say from their experiences. But either these things are very different for each individual, and extremely hard to discern, or there is also some degree of lying and/or deception involved.
I do not know if Mary K. Baxter has genuine saving faith, if she is a signs-and-wonders idolater; only God knows her heart and her personal challenges. But I do believe this book comes from a place between her personal imagination, and a general understanding of the gospel.
Who knows, maybe she even thinks she is doing us a favor, by claiming to have received direct revelation, so that then maybe many shall believe. But I suspect this book does more harm than good, and paints us Christians as mere crazy mystics chasing after visions, rather than lovers in reverence of the one true God.
From an artistic perspective, taking the book as if it were a work of fiction, it is also quite repetitive. The suffering, torture, and putridness of it all is shocking, but in a distasteful cheap kinda way. If you want darkness and supernatural shock, go read H.P. Lovecraft instead. If you want imaginative explorations of what hell might look like, go read Dante’s Inferno, or C.S. Lewis’ The Great Divorce. Those are great literature, and make no false pretenses of being special revelation.
