Don't think of this as just a book. Think about it as sitting down with an incredible person who has been through horrendous pain, and yet trusted God and was used by God in incredible ways before, after, and through it.
In My Father's House doesn't go into the details of what happened to her and her family during World War II. Corrie assumes that if you're reading this book, it's because you're familiar with her story, and therefore she mentions how she hid Jews and spent time in concentration camps only in passing, and only to make clear how her earlier experiences prepared her for those times.
This book did not meet my expectations; it exceeded them. I thought it would primarily be about Corrie's earthly father, and how as a loving believer, he laid the foundation for the ministry that Corrie would engage in. It does include that, but that's not what the book is about. I also expected that Corrie would use this dynamic with her father as an illustration of growing up in her heavenly Father's house, and how if we trust Him, we can have assurance of His love and plan no matter what we go through. And this is much more closer to the theme of Corrie's book, but even this doesn't quite capture it.
Corrie's book is how God works through everything, not just her earthly father, but literally everything, so that God would grow us into who He would have us to be. Even as she was cold and alone in prison cells, she was in her Father's house, and she could rest in Him. We often get so bent of out shape if the tiniest things don't go our way, but Corrie's story reminds us that God is always there and calls us to loving obedience and trust.
