Intra Muros recounts a vision or experience of life after death given to Rebecca Ruter Springer during a severe illness. She was unconscious for only a number of days, but the vision or experience covered a period of years. She did not claim to have died or have a near death experience. On reflection, she came to understand the short book as a series of truths about heaven.
Intra Muros includes some of her personal insights and encouragement. She did not describe her work as “prophecy” or infallible, but rather she intended it as comfort. As she noted, she wrote the book with “the hope that it may comfort and uplift some who read, even as it did, and as its memory will ever do, for me. I submit the imperfect sketch of a most perfect vision”.
