Spiritual matters will never be resolved with bickering back and forth on forums. Spiritual matters can only be resolved with the spirit. Our earth is filled with people ranging from spiritually dead to enlightened. This site also seems to have that same range with reviewers--prideful scripture citing, name calling, and cruel accusations.
Ms. Fenimore had this experience. It was real. Whether a vision or literal, does not matter. When Moses spoke to God, was he really talking with a burning bush? We are taught truths by means that enable us to understand, but always, our understanding is dependent on where we stand.
C.S. Lewis described being in a dark shed and observing a shaft of light penetrating a hole in the wooden door. From were he stood, he could see dust and fine particles floating, swimming, and swirling in the air. What he saw was truth, limited by his perspective and from where he stood. But as he positioned himself up near the hole in the door, a view of the beautiful outdoor world of grass and flowers and trees opened unto him. Interestingly, from both positions he viewed the same light (or truth), but observed different results. Some in this world are content to see the dust and argue there is nothing more. But those that want to see greater truth must align themselves spiritually. The choice is ours.
Years ago, my wife saw a talk show where Ms. Fenimore was telling her story. Later that day, my wife told me of Ms. Fenimore's experience. I felt the spirit whisper to me that it was a true experience. I wasn't seeking this revelation. It just came. Then just two weeks ago, my son came home telling me that one of his former friends that had been kicked out of junior high had committed suicide. The rumor turned out to be false, but reminded me of Ms. Fenimore's story heard some ten years earlier. So I googled NDE/suicide and found this book--didn't know it even existed before then.
I have since read BTD and once again felt the holy spirit witness to me. I believe it! Whether it's literal or visionary does not matter. The message is the same, and anyone that will humble themselves and spiritually align themselves can also know it's a true message. Others may be content with the specks of dust (truth) but please don't tell me that's all there is. This book opens up a world that we would not have seen without the courage of Ms. Fennimore and her willingness to share.
